HP-UX 11.0 CPU

[David Ryan_3]

How can I fix a process to a single CPU in a mutli processor environment?

Hi,

Under HPUX 11.00 this is only possible with PRM (not for free)

Under hpux 11i, you can do this with PSET

Hi David,

Still looking for the source... (compiled hpux11.11 but just tested on 11.00 and it works...)


All the best

Still looking for the source code, I wonder if it were not procura the author...

Hi again David,
The output you just saw in my previous reply comes from a K360 - it is the only multiprocessor box I have running HPUX11.00, the program was compiled on a RP5450 with HPUX11.11...


All the best
