Re: [Condor-users] Xeon + Opteron

Pasquale, 

I'll second that.  Cycle has seen many environments running with mixed Opteron/Xeon processors, without any issues. Like Carsten said, you may have to be careful if you're compiling for a specific processor.

Good luck,

Dave

Hi,

I would like to hear from other Condor users if it is OK to mix

Opteron and Xeon nodes in a Linux x86-64 Condor cluster. So far, our

cluster used only Opteron CPUs, all running a Linux x86-64 OS, but now

we're considering replacing the head node (submission only) with a

faster Xeon-based server. Any comment or experience sharing will be

appreciated. In particular, will it be fine to run on an Opteron node

a binary compiled on the Xeon server using condor_compile?

We basically have 99.x% Xeon CPus and a few Opterons and so far no problems. I
think unless you really compile for the specific cores.
