Threads Scheduling

HP 3000 Kernel Threads scheduling is handled through the dispatcher, therefore each

thread is visible to and known by the kernel. Altering the scheduling of one or more

threads in a task is accomplished with the same tools and methods used to alter the

scheduling of any non-threaded task.

NOTE The HP 3000 Kernel Threads Service is a kernel based implementation of POSIX

1003.4a Draft 4 threads. Individual threads created within a given task may use the

same processor at any given time; the threads are independently scheduled by the

kernel. Therefore, a multi-threaded process can take advantage of the increased

concurrency available on a multi-CPU machine.
