threads on hpux 11

[Bruno Misculin Rosamili]

Hi,
I need on hpux 11 to use the same threads behaviour of the 10.20 (without kernel threads and gang scheduling).
Is it possible?

bye

You asked the same question here:

The only way to turn kernel threads off in the OS is to revert back to 10.20 or FIX the application that is broken.

What is this MIDDLEWARE, who is the vendor and what is the application?

The middleware is "Forte".
We port the application on hpux 11 and some deadlock happens, we suppose because of the kernel threads.
The system is a production one.
We cannot spend days for developers job or
switch back to 10.20 so I'm looking for possible solutions.
I saw in manuals the parameter nkthread and the environment variable MP_GANG.

Have you some information about?

TIA

If you expressly set the contention-scope field (to PTHREAD_SCOPE_PROCESS) of the attributes-object used in your pthread_creat() call, then you can rest assured that no MORE kernel level threads than the minimal 1 per process will get created...

If your 11.00 specific problem persists, it lies elsewhere.

Good Luck,
