HPCx was a supercomputer (actually a cluster of IBM eServer p5 575 high-performance servers) located at the Daresbury Laboratory in Cheshire, England. The supercomputer was maintained by the HPCx Consortium, UoE HPCX Ltd, which was led by the University of Edinburgh: EPCC, with the Science and Technology Facilities Council and IBM. The project was funded by EPSRC. [1]
History
[edit]The HPCx was the flagship UK academic supercomputer from its creation in December 2002, to 2007 when the larger HECToR system was installed.[2] The HPCx service ended in January 2010.
Performance
[edit]The HPCx's service was divided into three phases, each with improved performance rates.
Phase one
[edit]Phase 1 of the HPCx service opened on 9 December 2002, although people had been using the service a month prior.[3] During the first phase, the HPCx consisted of 1,280 IBM POWER4 p690 processors with 1 terabyte of memory, the “Colony” switch and 18 terabytes of high-speed disk, performing at a peak rate of around 6.6 teraflops.[4]
Phase Three
[edit]By November 2006, the HPCx was given an additional 1,200 processors, leading to the performance of the supercomputer to rise to a peak of 15.4 teraflops and an average of around 12 teraflops.[5]
