PRIORITY_OFFSET is a system parameter that specifies the difference in priority required by the scheduler for one process to preempt the current process. A value of 2, for example, means that if the current process is executing at priority 1, a computable process at priority 2 or 3 is not allowed to preempt the current process. However, a priority 4 or higher process can preempt the current process. This mechanism affects only normal priority (0-15) processes. The default value is 0. This special parameter is use by VSI and is subject to change. Do not change this parameter unless VSI recommends that you do so.
