allows users to queue both batch and interactive jobs

abstract

The goals of EASY, Argonne National Laboratory's job scheduler
for the IBM SP,
are fairness, simplicity, and efficient use of the available resources. These
goals are in conflict, but the scheduler is designed to be a compromise.
Users are able to request a set of nodes for any type of use. In order
to maintain the quality of machine access, the scheduler provides a single
point of access, submit. This program allows users to queue both
interactive and batch access jobs. When resources are available, the user
is notified by the scheduler and at that time has exclusive access to the
number of nodes requested.
