Re: [Condor-users] How to set special requirements for a job

[Todd Tannenbaum <tannenba@xxxxxxxxxxx>]

Re advertising machines with special capabilities and then steering jobs 
towards (or away) from those machines, Steve gave the highlights below. 
 But you may also want to check out the HowTo recipes on the Condor 
Wiki at URL
  https://condor-wiki.cs.wisc.edu/index.cgi/wiki?p=HowToAdminRecipes

These HowTos give pithy specific instructions (e.g. cut-n-paste this 
into the config file) on how to accomplish common or non-obvious tasks 
in Condor.  In particular, the following HowTos may be of interest on 
this topic:

How to insert custom ClassAd attributes into a machine ad
https://condor-wiki.cs.wisc.edu/index.cgi/wiki?p=HowToInsertClassAdIntoMachineAds

How to steer jobs towards more desirable machines
https://condor-wiki.cs.wisc.edu/index.cgi/wiki?p=HowToSteerJobs

How to Manage GPUs
https://condor-wiki.cs.wisc.edu/index.cgi/wiki?p=HowToManageGpus

p.s. re GPUs, besides the above HowTo, we are looking at adding more 
tailored first-class GPU support into the code...

Todd
