Hi Meng, Thank you so much for being this patience. So a task set is composed of 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 Ti is defined by a period (and deadline) pi and a worse-case execution time ei, with pi â ei â 0 and pi, ei â integers. Each job is comprised of a number of iterations of floating point operations during each job. This is based on the base task.c provided with the LITMUSRT userspace library. So in a tasks set, there are many tasks, and in each tasks, there are a sequence of jobs, if any job misses deadline, then the whole taskset is qualified as failed to be schedulable.ÂThank you Victor
