SNIC Cloud Computing Course at UPPMAX, May 16
The UPPMAX computer system museum
Here we present a part of the history of UPPMAX computing and describe each of the computer systems once in use:
|
Isis
Isis, installed in 2007, decommissioned at end of 2010, consists of 200 IBM x3455 compute nodes, each with dual AMD Opteron, dual core, 2220 CPUs. 2 nodes have 48GB RAM, 20 nodes have 16 GB RAM, 38 nodes have 4 GB RAM and 140 nodes have 8 GB RAM. The compute nodes are interconnected with Gigabit Ethernet. |

Set
Set, installed in 2006, decommissioned at end of 2010, is a small IBM cluster at UPPMAX, consisting of 11 IBM p520. Ten of them are compute nodes and one is a login server. They each have two dual core IBM Power5+ CPUs, and the compute nodes have 8GB RAM. The compute nodes are interconnected with a fast low-latency InfiniBand switch. Cpu-hours on Set are not accounted for. |

Os
Os, installed in 2007, decommissioned at end of 2010, consists of 10 nodes identical with Isis’ nodes (IBM x3455, each with 4 cores), Infiniband interconnect and 8 GB of memory. On Os, you can test your job parameters and optimize your code before deploying it on UPPMAX larger resources. On Os, you can start interactive jobs with X-forwarding, which means that you can run a graphical X-program, e.g., Matlab, or your favourite software debugger/analyzer. |
