Hi David, Booker,
I mounted the xrootd space of the proof
cluster at /xrootd/proof on atlint01. It looks like we have ~1.8TB
total on the cluster. So something ~ 1TB should work.
The cluster should be able to access T2
storage if your provide the URL of those root file to process. But the
whole idea of using proof is to avoid network traffic as much as
possible. As we are still validation the functions, it would be good to
try both. Or if you put half of the data on proof cluster, and leave
the other half on T2 storage (no NFS please).
The proof master node is boer0123. If you
copy files to the cluster, the xroot URL is
root://boer0123//atlas/proof (I suggest you to create a fizisist
sub-dir).
Booker, it looks like proof also leaves
some file in the cluster. How would you suggest to manage the space, by
user, by group, or something else?
regards,
Wei Yang |

Hi Booker and Wei,
I have a few questions: from what
machine do we launch the jobs? Any machine at SLAC, but specifying the
URI correctly? Also, if the data are on atlasuserdisk or usr in
/xrootd/atlas/ is that sufficient?
Thanks,
David

Hi Booker,
I cannot access this machine

ssh -Y boer0123.slac.stanford.edu

It's on the slac internal network,
you'll need to login to a slac
machine and run root programs from
there. You shouldn't need
login access to the master node.
