MUN HPC Cluster

Memorial University hosts a cluster of DEC computers that can be used by MUN researchers and HPCnet members. All the computers run the Digital UNIX operating system and share disk and files using NFS, but they can be classified into three groups based on their primary functions:

Front End Systems (Plato, Kronos)

These are general purpose machines that allow remote logins. They are configured with the same software as the compute servers so that they may be used for software compilation, but users are generally not permitted to run compute intensive jobs on these platforms.

MUN Alpha Cluster (Alioth, Alphaid, Alcor, Mizar)

A number of single processor DEC alpha 3000 series machines. These systems are available to the MUN HPC user community. Users may submit batch jobs to run on these systems with LSF.

HPCnet System (Tempus)

Tempus is the four processor DEC AlphaServer 4100 5/400. Like the other systems in the MUN Alpha cluster, users are expected to submit jobs using LSF through the front end systems. Unlike the MUN Alpha cluster, this machine is available to all HPCnet researchers and represents a significantly faster resource with a much larger memory capacity.
