Need help: LightWeight processes?

OFC_EDM — Tue, 22 Nov 2005 13:15:38 GMT

Here's a question from my DBA:

This is sort of out of my realm. So I'm asking for guidance on how to answer this question.

"user threads are mapped to kernel threads so that they can execute on multiple processors. Likely through LightWeight Prcoesses (LWPs), maybe called MxN. If so there is a LWP pool kernel parm. How does this work in the hpux 11.11 and what kernel parms are associated"

There are 2 tunables which are of principle interest: 1) nkthread - system wide number of threads 2) max_thread_proc - per process limit. Glance has a display for currently running threads. A very good starting point which will lead you to other references is simply "man pthread".
