New Linux Cluster
October 31, 2002
The IS Group has put together a Linux cluster for
general use by CGD staff. The hardware configuration is 17 nodes:
1 master node w/ 16 compute nodes. Each node is configured as:
Dell Optiplex G260
CPU: 1 x 2.0 GHz Intel P4 w/ 512k cache
Memory: 1 GByte
Disk: 20 GB disk w/ 14 GByte available for scratch per node.
110 GB disk is available as shared disk space for all nodes.
Cluster Network: Gigabit ethernet.
Uplink to non-cluster NFS mounts (ie, /data, /fs): 100Mb/s.
The Portland HPF90 v4.0 compiler and debugger is installed, along
with MPI, and PBS as the queuing system. (PGCC still needs to be
installed.) The OS is RedHat 7.3 Linux.
A general FAQ is available at: http://www.cgd.ucar.edu/systems/documentation/faqs/CGD_Cluster.html
Usage is open to anyone with a valid CGD account, but access to
the cluster needs to be requested via WREQ.
