How much CO2 could the World’s Most Powerful Computer save with 2-phase immersion cooling?

As you may have read in the news, the 41st semiannual TOP500 list of the world’s most powerful supercomputers was announced a few days ago at the 2013 International Supercomputing Conference in Germany. Weighing in at a hefty 33.86 Petaflops on the Linpack benchmark, China’s Tianhe-2 Supercomputer packs quite the computing punch, and now holds the title of “World’s… Read More



Understand Immersion Cooling (PDF presentations)

Pictured here is the Immersion-1 FPGA cluster and Xeon Phi Immersion Cooling Concept shown at the HPCC Supercomputer Conference 2013. We’ve been working behind closed doors for a long time, but only recently we have been asked to come out and prepare a couple of presentations about the advantages and benefits of passive 2-phase immersion cooling,… Read More
