Most clusters are private. They are made of production servers that belong to research groups in various departments. Four clusters are made of workstations in student labs.
Processes of users are allowed to migrate to idle workstations and among nodes in private clusters, subject to the priorities among the different groups. For example, since the workstations belong to the CS department, processes that are started in a CS private cluster has a higher priority to move to a workstation over already running processes from the Chemistry cluster.
Due to the increased computing demands by our researchers,
the amount of installed memory in the workstations was increased
(beyond the needs of the students), to allow large guest processes
from the private clusters to run in these workstations.
