Title: Can Condor create more than one VM on single processor machines?

Some (although not I think latest) versions of Condor weren't up to speed on Linux 2.6 Kernel machines and 

got the number of processors wrong. The fix is the same, although if that is your situation a more recent version

could help.

 

You might also want to consider if you actually want the hyperthreading on. I have heard mixed things about

its use in any case.

 

Finally - you can leave it as it is and run twice as many Condor jobs on it - Higher Thoughput Computing ;-)

Miguel,

 

They could be Pentium IVs with Hyperthreading turned on.  They appear like dual processors to Condor.

Hi all,

I spotted vm1 and vm2 in a couple boxes, and according to IT there're no dual-processor boxes there (but they can be mistaken).

As a workaround, I can add

        VirtualMachineID == 1

to my requirements, and just forget about that, but I'm a bit curious (not to the extreme of opening the boxes to verify!).

TIA!
Regards,

Miguel
