Currently there are three scheduling schemes available with SCore: The SCore Multi-user scheduler and the SCore PBS batch scheduler, and Sun Grid Engine (SGE).
The Score Multi-user scheduler uses cpu and network time slicing
so that many users can share the resource interactively just as
though it was a single machine. The Multi-user scheduler only supports
SCore MPI jobs since there is a global daemon which timeslices the
bandwidth for MPI message packets. This scheduler is unaware of
other types of job - e.g scalar jobs (unless you run them as 1 node
MPI jobs by putting an an mpi_init and mpi_finalize around the code
and compile using mpif77,mpif90 or mpicc).
On the other hand the SCore PBS or SGE scheduler is aware of any type of job handed to it. However SCore MPI jobs are run exclusively; while the job is running the nodes are locked preventing other users from accessing them for other PBS or SGE jobs.
