The Blue Gene P hardware

The IBM Glue Gene series of machines is built around the prototype QCDSP supercomputer developed for lattice gauge theory. The Blue Gene P was introduced in 2007 and one rack was delivered to TIFR in 2009. It was then the second machine of its kind in India.

The Blue Gene P processor is an integration of four 850 MHz Power PC 450 processors. The ILGTI runs a two-rack configuration, where each rack contains 4092 cores. The theoretical peak performance of each rack is approximately 13 TFlops.

This machine was number 5 in the June 2009 listing of the top supercomputers in India. It reached a peak of 11.32 TFlops in the benchmark tests.

After enhancement in 2010, the machine was number 3 in the June 2011 listing of the top supercomputers in India, with a sustained performance of 23.25 TFlops in benchmark tests.

The same configuration was at number 25 in the June 2015 listing of the top supercomputers in India.
