Last week we were finally able to visit the (once sacred) holding ground of the MareNostrum supercompuer. The overall setup and presentation is very nice. The cables are neatly routed and you could tell there was attention to detail in making it look presentable. Not only that, but many of the stylish cues, such as the plexiglass enclosures, are functional as well. For example, each rack has has a dedicated cooling unit, which passes cool air in (within a plexiglass chamber), and the hot air is sent to the atmosphere outside, with the aid of fans to push it out.
