The Cray XC30 hardware

The Cray XC30 is a massively parallel supercomputer based on Intel Xeon processors and Nvidia Kepler graphics processors connected by the Cray Aries interconnect. This model was introduced in 2014. It was installed in a purpose-built data center in the old TIFR campus in Hyderabad in March 2015, and was the first machine of its kind delivered to India.

ILGTI's version of the XC30 contains 476 nodes, each with an Intel Xeon E5-2680 chip with 2.8 GHz 10 core CPU and a 2688 core Nvidia Kepler GPU.

This machine entered the June 2015 listing of the top supercomputers in India at number 3. It entered the Junr 2015 listing of the Top 500 supercomputers in the world at number 114. It reached a peak of 730.00 TFlops and gave a sustained performance of 558.7 TFlops in the benchmark tests.
