change bios settings via script

[Scott_Collier at Dell.com]

Jon,

 

You may want to take a look at this article:

nts/HPC_Dell_11G_BIOS_Options.pdf

 

The BIOS settings depend on the needs of the applications you are
running.  I think the noted article does a great job comparing options.

Could you provide a summary of the HPC settings Dell uses?

omconfig should be able to do it. You can also look on the support
site for the R410 and look for the Dell Deployment Toolkot (DTK).
The DTK is designed for enmasse BIOS changes.

BTW - you might want to look at your other BIOS settings. Typically
for HPC, HT is turned off and there are a few other settings (Turbo On,
C-state's off, max power, and one other I think). I'm betting the
account
team didn't put the HPC SKU on the order. The HPC SKU changes
the BIOS settings for you.

Hi,

I just received a shipment of several R410 that I'm going to use in a
compute cluster and I just found out that the hyper-threading is turned
on by default in the bios. Linux sees the two quad cores as 16 logical
processors. I need to disable it in 40 or so machines. Is there any way
of disabling it via a script? ipmitool, racadm, omconfig, anything??

Thanks, Daniel.
