From my reading HP-UX uses 4 different CPU scheduling algorithms: HP-UX Time-Share, HP Process Resource Manager, HP-UX Real-Time Scheduler, and POSIX-Compliant Real-Time Scheduler.
Here is where I am getting a little lost. Each algorithm seems to have its own priority, one higher than the other. Does this mean that HP-UX implements all four at the same time or does one choose to implement them singly and you have a choice of four algorithms?
Any insight would be appreciated.
Thank you,
