Use the MinSessions operator attribute to specify the minimum number of sessions needed to run a job. Larger systems are more likely to be enable to connect a sufficient number of sessions, whereas smaller, busier systems may often not have enough available AMPs to run the job efficiently. Proper setting of the MinSessions attribute prevents the job from running until there are enough AMPs for it to run at an acceptable rate.

Setting values for the MinSessions attribute should be done by running a job several times, observing the results, and adjusting the MinSessions value until it is optimal.
