| Linux Cluster system |
Specifications of the Linux Cluster:
- 152 Dell Precision 350 nodes, each containing:
- 2.66 GHz Pentium 4
- 1 Gbyte (533 MHz dual channel) PC1066 RAMBUS memory
- L1 cache (on chip): 12 Kb(I) + 8 kbytes(D)
L2 cache (on chip): 512 Kbytes (I+D)
- 100 GBytes IDE disks for job scratch
- on-board gigabit
-
Aggregate Specfprate_base of (compute nodes only) ~1800
Peak theoretical performance of over 800 Gflops.
- Total of 152 Gbytes of RAM on compute nodes
- 2 Dual Processor Dell PowerEdge 2600 servers for
interactive use and fileserving
- 1.4 TBytes global user storage (additional to node disks)
- 15 TBytes user scratch space for running jobs
- 140 GBytes system storage
- Total of over 16 TBytes of disk
- Dell 5224 Gigabit switches for interconnecting the
nodes.
The GrangeNet broadband network
is used to connect to institutions and centres that have signed up as
grangenet partners.
This allows fast access (gigabit) to the system for
distributed projects, especially those involving visualisation or
remote data repositories.
The status of the GrangeNet connections is monitored via the
GrangeNet
weather station. |
