Exploring New Horizons With The NSCCS Cluster
Home \| News \| Status \| Management \| People

The e-Science Centre of STFC runs a midrange computing facility for the UK Computational Chemistry Working Party to host the EPSRC National Service for Computational Chemistry Software (NSCCS).

It is comprised of two main systems - Magellan and Columbus-lx.

Magellan is a SGI Altix 4700 with the following configuration:

224-core, 1.6GHz, 18MB cache Montecito Itanium2 processors
896GB shared memory
15TB of RAID disk space

Columbus-lx is a boewulf compute cluster using Opteron compute servers. Each compute node has the following configuration:

2 x 2.4GHz Opteron 250 CPUs
8 Gbytes of memory
High speed low latency Myrinet network.

An additional Opteron node of similar specification acts as a columbus-lx cluster master node and hosts 1.5TB of RAID disk space.

SUSE LINUX Enterprise with SGI ProPack 4 is installed on Magellan and RedHat Enterprise Linux is installed on Columbus-lx. Users familiar with other flavours of Unix should find no difficulty in using the machines.

Information about how to apply for access to the NSCCS service and general user information is available in the User Area of the NSCCS website.

If you have any other problems or queries about the service please contact User Support
