requirements. A job allows you to schedule and schedule a task in advance so that it can be automatically executed once or multiple times at a specified time point or period. because the task is executed in the database, therefore, the execution efficiency is very high.Job allows us to customize the task execution time and provide a flexible processing method. You can also configure and schedule the task to be executed within a period of time when the number of system users is small, this great
Inter-process relationships: synchronous, mutex, and others.Shell Terminal: You can run a foreground job and any number of background jobs, which is called job control.Process Group : each process belongs to a process group in addition to a process ID. A process group is a collection of one or more processes.Typically, they are associated with the same job and can receive various signals from the same terminal.Note: as long as a process exists in a pr
As we demonstrated in ' A gentle introduction to Parallel computing in R ' one of the great things about R was how easy it is To take advantage of parallel processing capabilities to speed up calculation. In this note we'll show how to move from running jobs multiple cpus/cores to running jobs multiple machines (for even LA Rger scaling and greater speedup). Using the technique on Amazon EC2 even turns your
