How I miss Brasil, this was probably the most incredible experience of my life.  I have never had so much fun working on projects, learning, and laughing so much in my entire life.  The times I shared with my fellow FIU PIRE students and the CS people at UFF will always be in my heart. (wow that is sappy) now for some great pictures.

 

 

Oh I forgot to mention my first love in Brasil.  THE FOOD!

Seriously the food.

 

Also the drinks.

 

....After our lunch, Zaidi, Seijiro and I went to the "Maracana" one of Rio de Janeiro's famous landmarks. I have been dying to go to this place for years, and to finally be given the opportunity to experience a soccer game at "Maracana" was amazing. We arrived earlier than what we should have, one of the PIRE students thought the game started at 4:30pm which in reality started at 6:30, so we had to wait for almost 3 hours for the game to start. In the mean time we took some pictures out the stadium

 

At 4:30, they started letting people inside the stadium, we still had 2 hours left for the game to start, so we walked around and started taking pictures of inside the stadium 

 

Now the game finally started and let me tell you, it was one hell of an experience. I've been to many soccer games in Miami, and nothing an compare to the atmosphere of the Maracana. We decided to sit on the Flamengo side, the fans their were rowdy, jumping up and down, banging the drums and singing through out the entire game. The game was a nail bitter, the final score of the game was Flamengo 2, Botafogo 2, it ended in a draw.

 

Now as Americans we are addicted to cell phones.  Often we talk until we see the other person.  Constantly we see ourselves talking on the cellphone while we drive, walk, eat, and sometimes we even fall asleep while on the phone.  How do we break this addiction to survive in Brasil?

 

We buy a cell phone.

 Brasil and the cell phone industry

Now in Brasil cell phones are slightly different.  In the USA everyone has a cell phone, which puts a lot of capital into the infrastructure, which in return lowers the price of cell phone plans.  This then fuels our need to TALK ALL THE TIME.  Brasil does not have this infrastructure, so in return their prices are a lot higher.  So less people talk on the phone, thier efficiency is incredible.  Their manorisms will definately be adopted when it comes to cell phone efficiency.

The best option for fellow PIRE adventurers is to get a prepaid cell phone.  As Americans we are already familiar with the prepaid cell phone plans, but there is a catch in Brasil.  Due to the crime and the usage of criminals in prepaid cellphones, you must have a valid Brasilian ID to get a prepaid phone or SIM chip.  Somehow you need to buddy up with a Brasilian and convince him that you REALLY are a good guy and don't partake in criminal activity.

Carriers in Brasil

The best one I would recomend would be VIVO, they seem to have the best prepaid plan along with the best service.  The sales people aren't bad to look at either.  Most places with a cellular credit card machine can recharge your minutes with ease.  They run in packages of R$17 R$26 and R$60.  But be careful these calls are expensive and will not last long.  The actual cell phones for the base model can cost as little as R$49 to R$69.  For me, my purchase was one of these phones.

 

 

The best method would be to unlock a phone from the USA and purchase a chip.  Vivo keeps it exciting by giving you great graphics with your purchase. Most blackberries and Iphones can be unlocked and used with this chip.

 

For people that are in my situation, I purchased a cheap cell phone.  This is my glorious phone in action.

Yes my project finally got a name,  here is the abstract for it.

France is well known for its wine culture. In the Triskell research  team, it is usually the case that if a team member is leaving, he or she will host a little farewell party with some wine and traditional snacks, and all other members, including professors and staffs,  are invited to enjoy the wine and food. It is also the opportunity for networking and cultural exchange. During our stay here, we are fortunate to participate in such an event. It was great, pictures tell~

 

   

As an importang part of our PIRE experience, wenkend trips are always enjoyable and help us relax from the week. We spent the last weekend in Paris~ Unfortunately the weather was not that nice, we were walking along the Seine River in the rain on Saturday and climbed the Effiel Tower (around 700 steps!). The exercise kept us warm, though~  Then we went to Notre Dame. The design of the cathedral is really fancy and detailed! It is just  so delicate and eye catching!  During the time we went there, some religious activities were going on, people were singing songs and candles were lit up. All over the church, there are sculptures and things like such.
 
The next day we went to the Museum of Louvre and museum of D'orsay, saw the Mona Lisa and Van Gough's art pieces. You know how huge those museums so, and we just had to rush from place to place.
 
Another thing I want to metion is the arc of triumph: very magnificent monument~. We climbed up to the tower and enjoyed the view of Paris from the center of the radiant square~ Twelve avenues radiate from the square, all of which are named after famous people or battles.

 

 

 

WEEKLY STATUS REPORT
Sean Leslie
July 28, 2008

 

ACTIVITIES:
This past week we have been trying to fix various errors while working with spotty internet access. We also have been getting ready to go home and started getting information together to wrap up the project in general. A few changes to the namelist variable input page were made last week as well. While adding drop-down boxes to some variable with a fixed number of values was doable having them inside of if/else blocks was causing an issue we were unable to identify. A solution was chosen just to have regular input fields replace the combo boxes. Work was also done on creating java code that would parse a namelist file and take the values provided in the file and place them in the database. This required some critical thinking as the data fields did not have to appear in any particular order, or even appear at all. The string parsing works but requires testing on tomcat in order to be incorporated into the site.

 

We met with Dr. Duran and showed him what we had done so far. I also got to sight and have a 1 to 1 question answer session with him. We discussed various aspects of our project as well as WRF and grid-enabling it in general. It was a pleasure working with Dr. Duran he was helpful and responded to our questions in an honest and timely manner. If he could suggest a solution to a problem he would provide us with some web resources to look into the solution further, and if he could not help us he would tell us upfront. He proved to be a valued resource as we worked through problems while working in UdG.

ACCOMPLISHMENTS:
The namelist variable edit page can recall data from the database and add it to its fields, as well as submit data from its fields to the database.

 
ISSUES/PROBLEMS:

• I have been trying and failing to get winSCP working on my laptop. I have given up since we should be able to get this working from campus no problem.
• Having only one machine with winSCP means that only one of us could upload and debug at a time. It would have been great to have all of these tools installed and tested prior to getting to Mexico.

 

PLANS:
Short Term:

• Finish putting some aspects of the site together. Incorporating the work Seychelles and Elias have done with our own.
• Implement interaction with JFM
• Visualization

Long term:

• Finish up project documentation.
• Write a paper.

 

 

ACTIVITIES:

This past week we worked on getting Aprof to function properly on MareNostrum.  We amended Aprof’s source code to fix the way that it inputs data.  We amended Amon’s source code to account for the different version of Linux that is installed on MareNostrum in comparison to GCB and Mind.  We developed a script to combine the Amon outputs from each node into one file and to properly configure the data into a Aprof readable format.  We, also, worked to generate predictions using Dimemas and received a demonstration from the Dimemas developer. Personally, I worked extensively on my 2^nd REU Progress presentation and a bit on my Linux studies as time allowed. 
 

ACCOMPLISHMENTS:
In this part, please only mention your significant accomplishments that you have not reported previously. Note that you do not have to have an accomplishment each week.

-Aprof source code successfully amended

-Aprof functioning properly-Amon source code successfully amended

-WRF v. 2.2 compiled on Mind
 

ISSUES/PROBLEMS:
In this part, please mention the minor and major problems that you are facing in your research.

-We are still faced with some decisions on what we are going to do about the different versions of WRF installed at the different sites, GCB, Mind, and MareNostrum.  This is an important issue if we want to be able to make comparisons between the results generated on each of the different clusters. Right now v. 2.2 is installed on Mind and GCB and v.2.2.1 is installed on MareNostrum 

PLANS:
In this part, please mention your short- and long-term plans for the weeks and months to com.  

At this point we have obtained objectives 1, 3a, and 3b, and we are continuing to work on objectives 2 & 4. As this is our final week, we have set out two special objectives to complete before going home or shortly thereafter.   

1.      Get Aprof query automation and comparison script up and functioning properly on MareNostrum.  Obtain a results set of Aprof predictions for the different scenarios we are simulating for.

2.      Have full knowledge of how to run Dimemas simulations and set up Dimemas simulations so that the project can get its first look at comparison of the two tools. 

These are our main objectives to close out our experience here at the BSC.  Once these are complete, we can reassess the specific goal of the research with the first results and prepare to arrive at our significant conclusions by the end of the summer.  With this we will keep in mind the prediction accuracy of Aprof and Dimemas and how they compare and contrast to each other.  This should allow us to improve our approach and present our significant follow-up findings.   

Personally, I will continue my studies in the Linux platform. 

Barcelona Research Objectives 

Overall Objective: Achieve accurate and timely performance prediction on compute cluster to be used in Grid Computing Environment Meta-Scheduling. 

1.      Get mpidtrace linking properly with WRF compiled on GCB, then Mind. GCB COMPLETED

2.      Use generated MPI tracefiles (Paraver and Dimemas) to do prediction between Mind and GCB IN PROGRESS

3.      a) Install Amon and Aprof on MareNostrum. COMPLETED

b) Run benchmarks on MareNostrum FIRST RUNS COMPLETED

4.      Experiment with how well Amon and Aprof scale to larger number of nodes IN PROGRESS

5.      Analyze how Amon and Aprof relate to/could possibly combined with Dimemas.

6.      Work with  Marc to see how we can optimize the gridification of WRF 

SUMMARIES/CRITIQUES OF PAPERS: 

Readings temporarily satisfied.

Italy, Germany, and Portugal

Since its been a while since I mentioned what I do outside of my research (due to how much time I spend inside of it), here is some information about some of the fun I have had over the past few weeks. First, there was Italy, which all of us PIRE members here in Barcelona went to. Overall, it was a pleasant stay. Then came Germany, which was the trip I was most looking forward to and it was great. Finally, Portugal, which is where we celebrated Independance Day, was also a great place.

Italy

This was my first visit to a European country other than Spain, and it was intersting to see the similarities and differences. It was also the first time that I was in a country where I did not speak the language, which was quite difficult, yet strangely entertaining. We started off in a Rome, which was a very nice place with a friendly atmosphere. On the second day we went to Naples (Napoli), where there was more sightseeing and exploring to do. First, we went to the (ruins of) the ancient city of Pompei, which was destroyed by a volcano. Some of the structures were still in place and you could vaguely tell what they were (e.g. homes or restaurants), but very little. After getting back to Naples, we did some exploration of the city. It was not as pleasant as Rome in terms of views and cleanliness. Also, the beaches were a bit dissapointing since there was no sand. However, I was glad to see more of the "real Italy," as opposed to the more touristy Rome.

The next day was a shorter day, and it was Sunday so it was the proper day to stay again in Rome and go visit the (nearby) Vatican City. After seeing the huge cathedral and a portion of the Sunday mass, we went out to witness the Pope himself address the crowd. He spoke a prayer in various languages. Each corresponding country would of course cheer when he spoke in theirs. A great experience indeed.

Germany

I was eager to go to Germany since I found out that I was coming to Europe in the first place. As an auto enthusiast the reasons were this were the Autobahn and the Car Museums of the big european companies (Volkswagon Group, Mercedes-Benz, and BMW).

Arrival

Well, first of all, I missed the first bus to the Girona airport. Which meant that I was taking a bus that would get me there 20 minutes before the flight. Fortunately, I got the director to get a bus out 15 minutes earlier (>si estas leyendo esto, gracias). Traffic was good as well, so I ended up arriving with a few minutes to spare. My first stop was Hamburg, since it was the closest city to Wolfsburg (aka Golfburg for the Volkswagen Golf, which is popular in the area, and the fact that VW headquarters are here) that RyanAir had service to. Hamburg actually turned out to be a nice city, although I did not spend much time there.

p6261201 - I missed the first bus to the Girona airport, so this is what time I got there (for a 5:40 flight)
p6271214 - hamburg rail lines from central station

Day 1 - Wolfsburg

On the second day, I visited the VW headquarters an museum (i.e. the Autostadt). This was a huge place, so I am glad I scheduled an entire day for it. In fact, I was going to go to a nearby science museum, but had no time. The Autostadt is both entertaining and educational. I found out about design processes of the cars, a history of automobiles in general, with an emphasis on VW's role, and about future trends with alternative fuel sources such as their own SunFuel.

p6271251 - Inside the VW pick-up center, if you look close, you can see a bunch of cars lined up - vertically and horizonatally
p6271325 - Peice of decorated landscape. There were four of these, as there are four circles in the AUDI logo, which I came to find out stands for the four companies that merged to form AUDI in order to survive tough times. The next day I found out that the Daimler-Benz merger was done for the same reason.

Since Berlin was nearby and I had a few hours to spare after the Autostadt closed, I went by there, since that was the most touristy and historical place of Germany, although, frankly I was tired of such things after Barcelona and Spain. Overall, it was also a nice city, but frankly I have nothing special to say about it (I was only there about 4 hours). I include some pictures below.

Day 2 - Stuttgardt and (not quite) Munich

This day should have been two days, as I didn't anticipate how much time I would spend in city one (that and a mishap with the DeutcheBahn and being lost in translation). In any case, it was still the highlight of all of my getaways here in Europe. I started off going to the Mercedes Benz headquarters and Museum. I must recommend anyone interested in the automotive world to come here if they ever can because it is quite a spectacle. I spent much more time here than I expected to. I learned a bunch about the invention of the automobile and events that motivated and advanced the industry. I also learned some other interesting little facts, such as that "Mercedes," is actually not the name or any of the inventers (who are Daimler and Benz) nor their family, but rather the daughter of a race car driver who helped put their brand on the map. Purportedly, she never even learned to drive.

- Thanks to Daimler-Benz, even really fast runners were no longer able to escape the police (well, we can thank Motorola as well)
- Very cool stuff. Applications of EEG to improve driver safety

My next trip was to Munich, which is the home base of BMW. Their museum closes at 8 PM, so I should have had a couple of hours there despite staying at Benz so long, but a misunderstanding with the DeutcheBahn caused me to miss it. I ended up getting there are about half past 8. I still got to see it from the outside (boo hoo) and I saw some of the other things that BMW has there. They actually have an entire hotel there, with some of their cars inside. Additionally, there are a few small museum-like sections there. It is right across from the olympic stadium, which I passed by as well.

xp6281748 - Dome in the olympic stadium - Munich
- Festival-type thing by the olympic stadium. Intersting "cultural" experience
- Back inside the BMW hotel. I can't think of a better way to decorate the interior of a building (except maybe with Lotus' and Porsche's)

Overall, this was a very educational couple of days. Not only did I learn about the history of automotive, including the events that helped the industry grow so much, but I also became aware of some of the cutting edge research going on in the industry. Particularly intersesting were the EEG-based driver safety feature that Meredes is looking into, which I would like to look into some more, and the alternative fuels (or alternatives to fuel).

Last Day - Cologne

Cologne was the city with the nearest airport for RyanAir, so it was my final destination. It is also closest to the famous Nurburgring, which is a famous road for testing a cars limits (many automakers use it). Since I was unable to rent a car, I canceled my trip over here. Instead I opted to do some sightseeing in Cologne. This turned out to be a good idea, since there were some spectacular views.

xp6291803 - Catchedral at Cologne. You can hear the service bell pretty at a pretty far off radius from the cathedral itself, when mass is about to start
xp6291868 - At the chocolate museum. I got to see how one of these are made.


- Shot taken from a bridge at Cologne
- Cool scenery walking through the woods
- View from the top of the Cathedral. Getting up here requires climbing up 300 steps! (no elevator option)
- I didn't have much time at Frankfurt, so here's the Central Station with a nice skyline

Portugal

Note: I could not post any of the pictures of Lisbon since the USB output of my camera failed, apparently. I will modify this section when I am able to access the picture files

Portugal was my final visit to another country. This was another recommendation by Marlon. We spent all our time in the capitol, which is Lisbon. The city itself has a cozy and laid back feeling to it. People are generally friendly. In terms of tourist attractions and architecture, it was definetely the least extravagant of all the places I had been to, which helped to make it the most quiet and laid back. We had no official "plan of action" here. Instead, we went to a few of the cultural and tourist attractions. Of which there were a few statues. There was a very nice part that had a well-decorated peice of landscape and a nice view of the city.

We took a trip to the aqueduct, which was a fun adventure since it involved going through all kinds of terrain, but we weren't really able to see much of the aqueduct itself.

The next day we went to the bay area. First, we went by a park with a tall monument and then we went to the beach. The beach was surprisingly full for a Friday. The overall beach area was nice, although the water was just above freezing. Figuring I would probably not be visiting Portugal any more, I decided to jump in and try it out anyway. This was my first chance to test the waterproof abilities of my camera (it survived). Inadvertantly, I guess it also allowed me to test the freeze-proof feature, which it also survived. Altough perhaps this is what did the USB input in. Oh well.

London, United Kingdom

Top of the Day to you!  Well, the final week has come.  We are scheduled to return to the United States this coming Friday, July 18.  With this is mind, I was planning to just hang out in Barcelona this weekend, review some of my favorite sites in Barcelona, and perhaps take in some sun at the beach.  However, it is my belief that man may plan his steps, but the Lord orders his ways. So, to make a long story short, I ended up in London, England, this weekend. 

I was a bit annoyed upon my arrival to London’s Stanstead airport as I was grilled by the customs agent as to the purpose of my visit to the UK.  I thought, “What do most people do when they come from a different country to London?  They come to see the sites?”  However, the agent proceeded to ask me what I was doing coming from Spain and then if I had any documentation to prove that I was doing a research internship there as I told her.  This was interesting because I had never thought that I needed to carry documentation around proving that I was working in Spain for the summer.  Of course, I knew to carry my passport and a copy of my passport in a separate place, but I had not considered having this other documentation.  The way she spoke to me, I thought that this was something that was common sense to know.  Regardless, I knew that I had a valid US passport so that there was really no reason why she should have given me a hard time.  This was the first country in the five now that I have been to that has given me any trouble on entering the country with a US passport and go figure it to be our close friends (or so they say), the English.  In fact, besides when I first entered the European Union in Spain I have not had to show my passport again upon entering the new country.  England is part of the European Union in name but as I was soon to find out, their affiliation to the rest of the European Union wasn’t much more than via name. 

Once I passed through customs, I was in for another big wake-up call in the exchange rate between the British pound and the US Dollar.  I thought that the dollar really stunk in comparison to the Euro, but it is even worse with the British Pound.  One British Pound is, essentially, two dollars!  I was talking with someone who informed me that this was not the case as little as three years ago when the Dollar and the Pound were essentially of equal worth.  And then he asked, “I wonder what has happened in the last three years to change this?”  Now, I know that the American economy has worsened a bit in this time frame, but so has the global economy in general, and not to the point that the dollar is that week.  In my opinion, I could tell him what has happened in that time frame and his name is George Bush.  Much like a company’s stock price goes down when investors lose faith in the leadership of the company, a country’s currency goes down on the market when people lose faith in that county’s leader. And judging by the feedback that I got during my stay in England (and every other country I have visited—France, Spain, Italy, and Portugal), we have to do something about this and another of other issues and his name is Barack Obama! 

While in London I did the usual sight-seeing—Westminter Abbey, the Houses of Parliament, the London Tower Bridge, Buckingham Palace, etc. . However, there were a few experiences that invoked a lot of thought from me.  The first of these was the “Changing of the Guards” ceremony that takes place in front of Buckingham Palace each day at 11:30 am.  That’s right, I said “each day”.  For those of you who are not familiar with what this ceremony is, it is supposed to be the ceremony that signifies the change in the soldiers who are guarding Buckingham Palace, the resident in which the Queen lives in.  From the name, this sounds pretty simple, but it is anything but that and to be perfectly honest all of the pomp and circumstance is completely unnecessary and is obviously only a show for tourists.  The ceremony involves I would say nearly 100 British troops decked out in their red coats and their funny hats.  A band, troops on foot, and troops on horseback march into the gates of Buckingham Palace and, basically, don’t do much more than walk around in a fancy way for thirty minutes (!) and then march out leaving the 3 or 4 who are normally there.  My question was if it was absolutely necessary to have all of these troops take part in ceremony for the guarding of one person!  The other funny thing about it was that as the troops march in and out of the palace gates, they were escorted by the police!  I laugh as I thought about the US in parallel.  We would look plain foolish if we did this out in front of the White House each day and I think that we have better usage for our militia men.  I guess that this is the reason that we beat the British in 1776 and in 1812! 

The next really interesting thought that came to my mind was as I was riding a tour bus through what is known as “Piccadilly Circus”.  Now, does not imply what we would normally think this to be.  Piccadilly Circus is not actually a “circus” but rather a large intersection.  I couldn’t help but chuckle a bit when the tour guide referred to the square as being sort of like New York’s Times Square.  And I thought to myself, “He must be crazy? Or rather he has not been to New York’s Times Square.”  Yeah, Picadilly Circus is pretty busy and has a few billboards, but it lacks several tall buildings, more billboards, a lot more light, and few thousand people and is, therefore, far from Times Square!  The comparison would have been nice for them, but no, it’s not exactly accurate. 

The final interesting thought came when I was on a walking tour of “Royal” London, fittingly, led by an Australian tour guide.  I was very much so interested when he talked about the War Cabinet Rooms which were used by the Prime Minister, Winston Churchill, and the rest of the government during the German bombing raids on London in World War II.  The tour guide was actually quite good and he knew a good bit about the history of England and London, but he was a little too boastful for my taste, especially since he was not English but Australian.  Admittedly, I am a very proud American so we were bound to conflict on a few things. When we got to the Cabinet War Rooms stop on the tour he began to talk about the man who was voted the most popular British person in history by the British people, Winston Churchill.  He went on and on about how Churchill rallied a country with not much hope against Hitler’s war machine by saying that they will continue to fight the battle and shall never give up.  He then went on to say, in effect, that thus Churchill was the savior of Britain and the world in this conflict.  Again, I chuckled a bit…  I agree that Churchill was a great leader during this time, but my only objection was that Churchill had a little help in that winning the war part, specifically, coming from across the Atlantic Ocean.  At this the tour guide countered that  Great Britain had been fighting the war long before the Americans got involved and that he wouldn’t debate it too much further as there were other Americans in the tour that might get offended.  I accepted that, but I did have to counter with a couple of facts, lest he forget… First of all, it is true, Great Britain had been involved in the conflict since 1939. But even then, they were getting some American help in the loads of supplies that were shipped to Great Britain and the naval protection (granted German subs still reeked havoc) provided by the US Navy for British North Atlantic supply convoys.  I then, also, stated that obviously Great Britain wasn’t making much progress in the war as Great Britain was only losing ground as France would fall to Nazi Germany and expel the British from fighting on the European continent all the while as London continued to be bombarded with bombs by the German Luftwaft. 

Great Britain did have some success in fighting in North Africa, but the tides did not really turn until the Japenese dropped attack the U.S. Naval Base at Pearl Harbor and awoke a sleeping giant.  In my eyes, this was a major turning point in the war.  With this America shipped troops off to Europe to join the fighting.  When Allied troops made their return to the European continent in 1944 there were 10,000 more American troops than there were British troops that landed on the beaches of Normandy.  Churchill had help! Furthermore, this increased offensive on the western front allowed Russia to make advancements on the eastern front.  Churchill had help!  The French capital of Paris was liberated by the Free French Army who were ultimately under the command of U.S. General Omar Bradley, and two days later those were American troops that paraded through the Arc de Triomph in Paris and celebrated as liberators and not British.  Churchill had help!  But, I didn’t go into all of this for the sake of the tour, but I made the point clear.  Furthermore, the guy was Australian, not British so he couldn’t debate too far (I know that Australia is under the Queen as well, but still…it is supposed to be its own country)! 

Well, my trip to London wrapped up my weekend excursions for this experience, and what a wonderful experience this was!  It was quite a privilege to visit 5 countries and as many capital cities—Barcelona and Madrid, Spain; Paris, France; Rome, Naples, and Pompeii, Italy; Lisbon, Portugal; and London, United Kingdom.  However, from what I have seen of Europe, there is no place like the USA!  For instance, while the government center areas of these cities are impressive, they cannot compare to Washington, D.C.; and while these major European cities themselves are impressive, they cannot compare to New York, NY.  Furthermore, most of the countries over here have one, two, or three major cities that you can name by first name alone and everyone will know what you are referring to (i.e. Madrid, Paris, Rome, London, etc.).  The United States has numerous cities that, in my opinion, you could name without any further explanation (i.e. New York, Boston, Philadelphia, Washington, Miami, Atlanta, Chicago, Los Angeles, …).  I guess this can be attributed to the fact that, essentially, one of our states equals one European country.  This is what makes America so great, beautiful, and diverse in its geography and its people!  So, this experience has been wonderful and I have gained so much from it, but I am certainly proud and love the passport that I hold, the land of the free and the home of the brave, from sea to shining sea, from California to the New York island, the stars and stripes, the USA!
