Notes:

-We will compare the SV1 performance numbers to a single process T90 run.

-For parallel runs on the SV1, two types of runs will be distinguised; dedicated and non-dedicated

=Non-dedicated - no control over placement & threads will release processor if idle

=Dedicated - no-control over placement, but threads will not release processor

=Dedicated + MSP- control over placement and dedicated
