Gold Nodes
Description:
This system was acquired through grants from NSF,
Digital Equipment Corp., and the Keck Foundation in
January of 1995 and is owned jointly with the Institute
for Physical Sciences and Technology. The Cluster
contains ten Alpha 2100 4/275 nodes. Each node houses
four 275 MHz Alpha processors, 256 Mbytes of memory,
and about 10 Gbytes disk.
The cluster was origionally configured as part of
the LPDC DCE cell. Today, it's being converted to
RedHat 7.2.

Reservations:
There is no scheduler or reservation service on the gold
nodes. Common practice is to send e-mail to cluster-forum@umiacs.umd.edu
stating that you need sole access to certain resources during
a time frame.
Disk Use:
The internal disks are mounted as /scratch1 and /scratch2.
Please note that these disks are NOT backed
up, and no attempt will be made to retrieve data from failed
disks. Your home or group project directory should be used
to store data that you care about, please do not do any
massively I/O intensive work out of your home directory
since it is a shared resource.
