Xeon cluster
Hardware
- 17 nodes + 1 head node
- Total: 144 cores and 544 Gb
- 8.2 Gb Raid array mounted as /home
- Head node is a single Viglen HS316i 3U unit:
- Dual Xeon E5430 2.66 GHz quad-core processors
- 32 Gb memory
- Quoted 2008-06-16
- Delivered 2008-08-25
- Operational 2009-02-09 (lag because no server room)
- 8 nodes are housed in four Viglen HX2225i 1U units:
- Each node is an 8-way SMP ( Super Micro 6015TW-TV )
- Dual Xeon E5430 2.66 GHz quad-core processors per node
- 32 Gb memory (shared) per node
- Quoted 2008-06-16
- Delivered 2008-08-25
- Operational 2009-02-09 (lag because no server room)
- 5 nodes are housed in five HX225i Viglen HX225i 1U units:
- Dual Xeon E5430 2.66 GHz quad-core processors per node
- 32 Gb memory per node
- Quoted 2009-02-06
- Delivered 2009-02-25
- Operational 2009-06-29
- 4 nodes are housed in a single Viglen HX420T2i 2U unit:
- Dual Xeon E5520 2.27 GHz quad-core processors per node
- 24 Gb memory (shared) per node
- Ordered 2009-11-18
- Delivered 2008-08-25
- Operational 2010-01-25
NOTE: 4 nodes report 16 processors because they run in hyperthreading mode. So 176 processors show up on a scan of /proc/cpuinfo (168 without the head node).
The E5430 is a member of the Harpertown series, released in November 2007. Power consumption for the 45 nm chips is 80W. Front side bus runs at 1.3 GHz. The series runs up to 3.4 GHz at 150W, so I expect the chip to be rather stable at 2.66 GHz and 80W. The L2 cache has 6MB.
The E5520 is a member of the Gainestown series, released in March 2009. Power consumption for the 45 nm chips is 80W. Front side bus runs at 1.0 GHz. The L2 cache has 1MB but has an 8MB L3 cache.
