EKA (Supercomputer)

EKA is an Indian supercomputer. In the current TOP500 list (as of November 2012), he is ranked 186 of the fastest computers in the world. EKA was the first supercomputer from an emerging country that has made ​​it into the top 10 rankings of the TOP500 list. The designation EKA is Sanskrit and means " number one ".

In addition, EKA was with his entry into the world's most industrially used system (the other located at that time in the top 20 list of the computers were all financed with government funds ). EKA is for neural and molecular applications used (eg, molecular design, molecular dynamics ), crash simulations and computer animations. EKA was developed at the Computational Research Laboratories (CRL ) in Pune, which is a subsidiary of India's Tata Group.

EKA is based on a designed and delivered by HP Xeon cluster ( Platform 3000 BL460c ), in which almost 1,800 compute nodes with 14,240 so-called " Clovertown " processors ( quad-core Xeon processors), clocked at 3 GHz are used. To their connection an InfiniBand network in the Double Data Rate Variation ( DDR) is used, and indeed the world for the first time using fiber-optic technology ( fiber optic cable ). As a Linux operating system will be used.

The layout of the data center is approximately circular, what an extremely compact design enabled. Such computer architecture was first applied in this order at EKA.

The system has a peak power ( Rpeak ) of up to 170 teraflops ( 170 trillion floating point operations per second) and a continuous output of 117.9 teraflops on the Linpack benchmark.
