  1. HPCX Phase 4 Extension • Service extended until Jan 31st 2010 • Maintain current overall performance and reliability • Move from 160+ nodes at 1.5GHz to 120+ nodes at 1.9GHz as quickly as possible • 2 high memory nodes (128GB) included • 14 Day Node Swap Program • Non disruptive transition • Aim to maintain a minimum of 128 nodes during transition (mix of Power5 and Power5+) • Concludes with 120 Power5 + nodes

  2. Replacement Hardware Phase 4 will replace the Phase 3 Hardware with a cluster of 120 IBM System p5 Model 575+ servers; each of these nodes will contain 16 x 1.9 GHz processors, giving 1,920 processors in total. 118 of the 120 nodes will be equipped with 32 GB memory, while the remaining 2 nodes (32 processors) will have 128 GB memory I/O, networking, system SW and Storage is unchanged.
