Bad politics.
Is there a way of finding out within Linux if Hyperthreading is on or not? I know there is a BIOS setting but one of the machines I am testing is remote and I do not have access to BIOS. I'll ask them though but I am impatient to figure out! Alternatively /proc/cpuinfo shows a bunch, say 16, cores. Is there a way to find out if all of these are real cores or hyperthreaded? -- Rahul _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
