The Cray X1 hardware

The Cray X1 is a shared memory multi-vector processor. This model was introduced in 2002 and delivered to TIFR in 2003. It was then the first machine of its kind in Asia. All the work done between 2003 and 2008 was performed on this machine. Even now it continues to be used on several projects.

The ILGTI runs a Cray X1 with four boards. Each board has four multi-stream processors (MSPs) each with a rating of 12.8 GFlops. The theoretical peak performance is 204.8 GFlops. The X1 has a 800 MHz clock.

The Cray X1 was decommissioned in June 2015. It was the longest-running machine of its kind in the world.
