Time really flies during these internships. It feels like last week that I was sitting at home here in Miami. Then I started thinking about all the things that occurred during the time. The Miami Heat getting to the finals (yay). Loosing the Finals (boo). The Memorial Day and Independence Day celebrations in NYC. And several other things. The last few days were quite intense, preparing a 1 hour presentation and trying to come up with a plan for the coming months.

Initially, I was concerned as usual about our accomplishments. Then I started thinking about our accomplishments. We fixed some bugs, implemented some new algorithms, discovered some helped at times, wrote a paper, etc. Actually, being able to go through the paper section by section and getting feedback from my collaborators there was a great benefit. I consider their feedback very valuable given their industry prospective (and the number of best paper awards they have received.

Another thing I was able to take advantage of last week was a MATLAB workshop that was being held at Yorktown. All my programming work with these collaborators is done in MATLAB. Performance is the only drawback with this environment, and the workshop specifically focused on performance. As I found out, there is a code generator included with the new version of MATLAB that generates C code from MATLAB code. This should allow us to improve performance pretty easily. I was able to obtain a 30 day license thanks to one of the representatives there, so I will spend the next few days playing with that. I've already noticed that they've made the Mac interface better, at least compared to the 2009 version I'm currently running.

 All in all, it was a fruitful internship and I'm sure it will show in the quality of our outcomes in the coming months.

Last week we accomplished a milestone by submitting another paper. This time, to the Utility and Cloud Computing Conference. We were all at it until late at night. (See below for a picture of the Hawthorne parking lot at 1:30A.M.) We were pretty happy with the paper and it should be a good contribution for this conference, since there is a keynote on HPC in the cloud and the "diamond sponsor" is HPCWire. Now, I need to take advantage of physically being here by planning the next steps and discussing them with the group.

Last week week there was a department picnic, which was a nice networking opportunity. There were several activities, such as soccer, volleyball, badminton, and even a water baloon competition. The event took place at Croton Point Park, which is a really large county park with great views, as shown below.

Getting back to reality, this week was once again non-stop work on the paper. Its looking better and better, but there's still work to be done and the deadline is tomorrow night. We're currently working on compressing the paper down to 8 pages, which is pretty hard since we have so much data after working on this for several months. The focus of the paper is on the effects experienced when scheduling parallel jobs on virtualized resources, which we all think will be an interesting topic for the UCC conference.

A nice place to sit back, relax, and...read your conference paper, of course

I've spent all week working on a paper for the UCC conference, with plenty of support from my group here. They've actually all had different priorities this summer, so I'm glad we have still been able to meet at least twice a week to discuss the project. I think the effort we've been putting in is apparent in the paper. Hopefully, the reviewers will see it the same way.

I don't really have anything else I can comment on anything work related since the focus has been on just the paper. In fact, there was a presentation on Thursday about the "Watson" project, but I forgot all about it. I did go indoor rock climbing with Liana (my manager) and some other "IBMers" on Thursday, which was a nice way to relieve some stress. It was Liana's first time and she did surprisingly well! I've done it a few times back in Miami, so it was good practice for me. Unfortunately I forgot to take pictures, so I have nothing to post for this week.

Looking through my pictures today, I realized I hadn't posted anything from the Macy's Fireworks event on independence day. This was the first time I was in New York for the event, and it was well worth attending, despite the traffic, crowded trains, and crowded streets. I can't recall having ever seen such an impressive fireworks show.I took a few pictures, but they did not come out very good, so I'll include a short video when I have access to  a faster internet connection. In the absence of fireworks pictures, here's are some nice shots from NYC.

For the next couple of weeks, we need to focus on putting about a year's worth of experimentation, observations, figures, and algorithm changes into about 8 pages of 2-column text. This naturally a tough undertaking, but we have the benefit of being close to each other this time. For our last paper, which was published at the SMTPS workshop held at IPDPS this year, the 6 of us were working remotely, which was considerably challenging. We spent about 8 hours on a call the night the paper was due, which was particularly uncomfortable. For this paper, we can actually sit down and discuss the direction that we are taking with the paper and brainstorm together to get an agreement about what we will write about, such that we get a coherent message in the paper. So I am pretty confident that we will have something good by the deadline, even though we are low on time and there are other deadlines to juggle with. 

On the other hand, I have a camera ready submission due this Friday, and for this one my collaborators are back home in Miami, so its going to be a little more time consuming to get that one done than it would normally be. Fortunately, I've had some experience with this kind of remote collaboration so I'm sure we'll pull through.

Its amazing how different things are just 20 miles south of the Hawthorne IBM lab. One of my fellow interns co-workers was kind enough to give him tickets to a NY philharmonic orchestra for Wednesday. He graciously invited me to tag along to watch the show. I had never been to one of these events, so I didn't know what to expect. I can't say I'm a fan of classical music, except when I need to isolate myself from outside noise, but I can appreciate nice sound. I was quite impressed with the performance. I'm sure the performers were very good, so I guess my ears are now spoiled when it comes to live orchestra. 

After the show we walked around a bit to experience the NYC culture a bit. I always go on weekends, but its hard to tell the difference in the city that never sleeps, the place was lively as ever. In Westchester county just a few miles up, on the other hand, about 90% of the places are closed by 9PM or so. There was an ourdoor music event being hosted courtesy of Macy's with live Swing music.  The streets were filled with as much people as I'm used to seeing there during the day on the weekends. Since it was mid week, we couldn't stay for long, but I am glad I got to see it.

Since the goal of this year's PIRE internship was to accelerate the pace of some work we have been working on since last year, rather than starting a new project, I have had more time to really think about the work. Last year it took a lot of time just to catch up. So far, we have found many interesting things, although we're still trying to find an explanation for some of our results. Fortunately, the group has set aside plenty of time from their busy schedules to brain storm together a couple of times a week. Since we don't have the physical boundary that we usually do during our meetings while I am not here, meetings are much more productive. We've found a couple of bugs that have slowed us down a bit, but other than that we seem to be going in the right direction.

Now that I have some simulations running, I have some time to talk about some of the social events going on here at T.J. Watson. One of the things that I've really tried to take advantage of is hiking, since there isn't much of this back home. There is a group here that goes out every Tuesday night. I found out last week that they've been doing this since the 1960's! The turnout is actually quite large, about 20-30 people every week. There are over 100 trails in the area, so its hard to get bored. For me personally, its a very different experience compared to what I see back home.


Here are some pictures from the last 2 events.

Today was the welcome event for IBM interns. A bit of a late welcome for me since I started earlier, but it was a nice event. There were fewer students than last year, which I guess is a sign of the times. Fortunately PIRE is still providing the opportunity. All in all it was a good chance to de-stress a bit. Several uncommon games were played and our team won one of them, so now I have an extra shirt to wear (and an extra day between laundry sessions).
