System X (computing)

system x computing innovations, system x computing bmi
System X pronounced "System Ten" was a supercomputer assembled by Virginia Tech's Advanced Research Computing facility in the summer of 2003 Costing US$52 million, it was originally composed of 1,100 Apple Power Mac G5 computers with dual 20 GHz processors System X was decommissioned on May 21, 2012

System X ran at 1225 Teraflops, 2024 peak, and was ranked #3 on November 16, 2003 and #280 in the July 2008 edition of the TOP500 list of the world's most powerful supercomputers The system used error-correcting RAM, which is important for accuracy due to the rate of bits flipped by cosmic rays or other interference sources in its vast number of RAM chips

The supercomputer's name originates from the use of the Mac OS X operating system for each node, and because it was the first university computer to achieve 10 teraflops on the high performance LINPACK benchmark The supercomputer is also known as ‘Big Mac’ or ‘Terascale Cluster’ In 2003 it was also touted as “the world’s most powerful and cheapest homebuilt supercomputer” System X was constructed with a relatively low budget of just $52 million, in the span of only three months, thanks in large part to using off-the-shelf Power Mac G5 computers By comparison, the Earth Simulator, the fastest supercomputer at the time, cost approximately $400 million to build

Upgrade to Server-Grade Parts

In 2004, Virginia Tech upgraded its computer to Apple's newly released, Xserve G5 servers The upgraded version ranked #7 in the 2004 TOP500 list and its server-grade error-correcting memory solved the problem of cosmic ray interference In October 2004, Virginia Tech partially rebuilt System X at a cost of about $600,000 These improvements brought the computer's speed up to 1225 Teraflops, which placed System X #14 on the 2005 TOP500 list
