UW-Madison CS Dept. Globus Access

Select users can access the UW-Madison CS Department's Condor pool through Globus. If you would like this sort of access, please contact us by sending email to condor-admin (at) cs.wisc.edu.

Here are some things you need to know:

• You should read our information for users at the UW.
• We have two Globus gatekeeper, north and south. They are both running RedHat 9.0. You can submit your jobs to our them at:
  • north.cs.wisc.edu/jobmanager (fork jobs)
  • north.cs.wisc.edu/jobmanager-condor (Condor jobs)
  • south.cs.wisc.edu/jobmanager (fork jobs)
  • south.cs.wisc.edu/jobmanager-condor (Condor jobs)
  
  
• GridFTP is running, but you will have problems accessing files on AFS with GridFTP. You should access files on local disks (/scratch on beak) or NFS.
  
  
• There is no running MDS Server at this time.
  
  
• As of Summer 2004, our Globus gatekeepers are running VDT 1.1.13, which corresponds to Globus 2.4.3. We do not yet have Globus 3 or any OGSI services.
  
  
• If you need to a large amount of data, it is best done on NFS. We have three NFS areas you can access:
  • /shared/scratch
  • /shared/scratch1
  • /shared/scratch2
  These NFS volumes are shared with the dedicated nodes of our Condor pool. All of your files in any of these directories should be stored in a subdirectory with the same name as your login name. For instance, if you login name is roy, you might store files in /shared/scratch/roy. To create this directory, you may need to ask a Condor staff member, since you probably have insufficient privileges.
  
  
• You may need to link your GASS cache to a space on NFS in order to avoid AFS permissions problems. For instance:

  mkdir /shared/scratch/(your-name)/gass_cache
  ln -s /shared/scratch/(your-name)/gass_cache ~/globus/.gass_cache

  Either that, or you will need to open up permission on your GASS cache so anyone can read it:

  fs setacl ~/globus/.gass_cache net:cs rlidwka

  This is probably a bad idea, since it opens up the permissions so everyone in the CS department can read and write your files in AFS.
