2 PDC Site Update at HP-CAST NTIG 1st April 2008 by Peter Graham PDC premises since 2004

3 PDC Site Update at HP-CAST NTIG 1st April 2008 by Peter Graham

4 PDC a Centre for HP Scientific Computing (HP=High Performance) HP Itanium cluster Lucidor

5 PDC Site Update at HP-CAST NTIG 1st April 2008 by Peter Graham upgraded in 2007 to… HP Itanium cluster Lucidor 2

6 PDC Site Update at HP-CAST NTIG 1st April 2008 by Peter Graham Lucidor2 at a glance The system contains 106 nodes, each with four Itanium2 (McKinley) 1.3GHz CPUs. 22 nodes have 48 Gb RAM and the rest have 32 Gb RAM. At least 64 nodes available for general (i.e. SNIC) user. The interconnect, Myrinet 2000, now uses MX stack which improves latency. Myrinet M3-E128 switch is populated with 112 ports. Each card/port has a data rate of 2+2 Gbit/s, all through 50/125 multi-mode fiber. Linux distribution CentOS 5.

7 PDC Site Update at HP-CAST NTIG 1st April 2008 by Peter Graham Latest HP addition ”Key” HP SMP system (donated to KTH in 2008) Key is a shared memory system consisting of GHz cores of IA64 (Intel) type with 18 MB cache. The total main memory will be 256 GB. (named after Ellen Key)

8 PDC Site Update at HP-CAST NTIG 1st April 2008 by Peter Graham Current systems Lenngren, 442 nodes, Dell 1850 Lucidor2, 106 nodes, HP Itanium2 SweGrid, 100 nodes, South Pole Pentium 4 SBC, 354 nodes, Dell P4 and South Pole Athlon XP Hebb, IBM BlueGene/L New systems: Key, HP SMP, 16 nodes Ferlin, 680 nodes, Dell M600 blade SweGrid2, 90 nodes, Dell M600 blade Climate and turbulence system, under joint procurement with NSC, for SMHI, MISU at SU and Dep of Mechanics at KTH

9 PDC Site Update at HP-CAST NTIG 1st April 2008 by Peter Graham Infrastructure power & cooling Change of transformer from 800 kVA to 2 MVA, done Upgrading of UPS from 400 kVA to 1100 kVA, in progress Diesel generator 400 kVA, existing Upgrade of cooling exchanger, done Adding 300 kW APC cooling hut for Ferlin and SweGrid2 Addition of 300 kW chiller for redundant cooling, in progress

10 PDC Site Update at HP-CAST NTIG 1st April 2008 by Peter Graham Price-performance vs energy Power per node W Energy cost for 300W over 4 years is nearly 15 kSEK If you pay 15 kSEK per node you spend equal amount on investment and energy To develop more energy efficient nodes will give a competitive advantage We would prefer to spend money on application experts rather than on energy bills

11 PDC Site Update at HP-CAST NTIG 1st April 2008 by Peter Graham Summing up PDC is tripling power capacity to meet the need of the new systems coming in High density cooling is required for the new systems with around or above 20 kW per rack Energy efficiency, both in regards to cost but also out of environmental concern is becoming more important Our new patch cables… -->> (for the UPS)
