Re: [HTCondor-users] Condor + Xeon PHI

[Tiago Macarios <tiagomacarios@xxxxxxxxx>]

Hi Lans,

It looks like that it is "easier" to use than GPUs and if you are using the intel compiler it can sometimes be only some extra calls. http://goparallel.sourceforge.net/wp-content/uploads/2012/10/SF12_SFTS001_101.pdf

Also I remember some discussion about multiple GPUs not working on Condor when using windows. Would that be a problem with Phi? Not sure it is "recognized" as a GPU...

Thanks,

Short answer is "yes".

The slightly longer answer is that they have completely different
roles from each other, and will require integration.  Just like GPU's
or any other specialty compute hardware - you model and expose the
host resources as metadata for your scheduler to utilize and reserve
special slots around.  The support for utilizing the specific hardware
has to be written into job wrappers and applications, and infers a
workflow and specific integration/configuration that you'll have to
develop.  You probably want to start with the GPU wiki page:
