[Barrelfish-users] Running benchmark on multiple cores

[Georgios Varisteas]

Hi

I assume you are using Qemu. The downside with this emulator is that it will only use one core from the underlying system, even though you can ask it to emulate up to 255. Also, you can not use the host OS' monitoring tools to check on any emulator's load, as they will constantly appear as using 100% of the core(s) they run on.

I have tested BOMP myself and it runs correctly. I propose to use a different emulator. I have found VirtualBox to be a very good tool for quick and easy trials.

Best regards,
Georgios Varisteas

Hi,

Can you paste the menu.lst file or fish command you used to run the benchmark? Did you pass the number of threads to use as the command-line argument to the benchmark programs?

What do you mean by "when I check the system monitor"?
