Re: [Condor-users] Condor and GPUs

[Miron Livny <miron@xxxxxxxxxxx>]

All,

How should we go about collecting the requirements for the most basic 
support we should offer in this space. What I am looking for is input 
that will help us pick the right cost/benefit ratio for an effort to 
support GPUS and/or multi-core nodes.

We are definitely interested in enhancing Condor in this direction. 
Help in deciding what we should do first is most welcome.

Miron
