Don't know much about this stuff but I am told the Hyperthreading stuff is to do with accessing/fiddling with the BIOS. Correct? There's no way of turning it off/on as/when one wants. I have no intention of playing with the BIOS !

I am not even sure why this option is currently on.

Hi selex_Ct

 

Generally, By default hyper threading is enabled.

It is also well documented in NX Nastran installation and operation guide, that we need to disable.

 

 

""Some Intel processors provide a Hyper-Threading feature in which a single processor can support multiple instructions, thus emulating additional processor cores. When Hyper-Threading is enabled, it can lead to a conflict with threading within NX Nastran for both SMP and DMP executables. Hyper-Threading should be disabled, which can be done permanently through BIOS operations""

thanks for the info.

I don't use dmp and nastran jobs are run with smp = 0 as it is the default

Hi there,

I'm running the model blas made, we don't have FEMAP here...  Looks like it's a small model, 700k dof...

Interesting benchmark to perform on a bigger model indeed!
