I suppose you mean "Symmetrical Multiprocessing" (SMP). Multithreading is automatically enabled if you use the correct libraries for your softwre development (libpthreads.so).
The multiprocessor kernel resides in a package called "bos.mp", whereas the uniprocessor kernel resides in "bos.up". One can have installed both and decide which one to use.
First check what is installed on the machine. The command and its output should look similar to the following:
Then check which kernel gets booted on system startup. The kernel to get booted is "/unix", which is a link to the kernel file:
You can use the bosboot-command (as root) to alter the kernel to boot, the boot image, the device from which to boot, etc.
PLEASE READ CAREFULLY the manpage of bosboot prior to usage - you can easily render your machine useless and ready for a reinstallation by (mis-)using this command.
Hi,
I have a POWER8 server running in Processor Implementation Mode: POWER 7.
I have 2 LPAR's, both are capped with 4 cores.
One of them displays:
Shared-SMT-4
and the other:
Dedicated-SMT-4
What is the difference when running in capped mode?
Thanks (1 Reply)
I'm working on a system to monitor a wide-range of Unix platforms, and I'd like to know if HP-UX has anything similar to AIX's SMT (simultaneous multithreading)? If there a way to separate an HP-UX CPU into multiple logical partitions which can then act as multiple CPUs?
Thanks in advance,
