Here is why IBM supercomputers have taken the top three spots on the latest Graph500 list.

The list captured by Connectikpeople has been released today during the Supercomputing Conference (SC’13) in Denver, Colorado. The biannual list ranks high-performance computing systems on the basis of processing massive amounts of Big Data. This rank consolidates the IBM commitment to make its supercomputers essentials in terms of the processing massive amounts of Big Data, cost-effective and
features.  
Connectikpeople recalls that, the top three positions have been awarded to Lawrence Livermore National Laboratory’s Sequoia, Argonne National Laboratory’s Mira and Forschungszentrum Juelich’s (FZJ) JUQUEEN, which all use IBM Blue Gene/Q systems.
Regarding the Graph500, it was established in 2010 by a group of 50 international HPC industry professionals, academics, experts and national laboratory staff. There are five key industries that the Graph500 tries to address with its benchmark which include cybersecurity, medical informatics, data enrichment, social networks, and symbolic networks.
The Graph500 was established as a complement to the TOP500 list, which ranks supercomputers based on performance speed via a benchmark called the LINPACK.
