Hi Meng, Thank you very much for replying! The
RT tasks I am running for each trial at a certain utilization rate is a
collection of real-time tasks, and each real-time task is a sequence of
jobs that are released periodically. All jobs are periodic, where each
job is defined by a period (and deadline) and a worse-case execution
time. Each job is just running of a number of iterations of floating
point operations. This is based on the base task.c provided with the
LITMUSRT userspace library. So Yes they are independent and not I/O or
memory intensive. The period distribution I have for each task is (10ms,100ms) which is bigger than the VM period I specified using xl sched-rtds (10000us), but I guess the lower bound is too close to the VM period. So by your suggestion, maybe shorten the period for VM can improve the performance? Thank you!
