NOAA Scientists Study Historic âDust Bowlâ and Plains Droughts for Triggers. Knowing Different Global Causes Could Aid Future Drought Warnings. The remains of a cornfield after grasshoppers had completed the destruction begun by the Drought of 1931-1932 in Montana, North Dakota, South Dakota, Nebraska, and Washington.
The short-term scheduler (also known as the CPU scheduler) decides which of the ready, in-memory processes is to be executed (allocated a CPU) after a clock interrupt, an I/O interrupt, an operating system call or another form of signal.
In computing, scheduling is the method by which work specified by some means is assigned to resources that complete the work. The work may be virtual computation elements such as threads, processes or data flows, which are in turn scheduled onto hardware resources such as processors, network links or expansion cards. A scheduler is what carries out the scheduling activity.
