The Parallel Collective Cluster is composed by 12 computers (fp1-fp10, asdrun, and qwerun), and a transparent NFS/NIS fileserver (qwes), connected to a switched 100-Base-T network.

There is no direct console access to the computers from the parallel cluster. All the access should be done remotely via ssh.

The hardware: The cluster is based on the x86 Intel platform. Various nodes have the following architecture: the two *run gateways are quads PPro 200 MHz, 512Mb RAM; the fp* computers are duals PII 300-450MHz, 256-512Mb RAM.

The software: All the machines are powered by an operating system based on Redhat Linux 6.2 and one of the latest 2.2.*  kernels. Here is information about specialized software packages installed on the parallel cluster computers.

About sharing:

The network filesystem containig the users home directories is shared to the qwe computers (qwe1-qwea), so an user will see the same files from either the parallel cluster or the qwe cluster.

Each node of the parallel cluster has a large /tmp directory (typicaly a few Gb) which can be used as temporary short term storage for data, binaries, intermediate results. This disk space is not shared from one computer to the other.
