Information about job submission to OSG sites

This page captures some of the known quirks about certain sites when submitting jobs there.

What this page is

Most OSG sites will work with with the jobsub default requests of 2000 MB of RAM, 35 GB of disk, and 8 hours run time, but at some sites there are some stricter limits. Additionally some sites only support certain experiments as opposed to the entire Fermilab VO. Here we list the OSG sites where users can submit jobs, along with all known cases where either the standard jobsub defaults may not work, or the site only supports certain experiments. Information on it is provided on a best-effort basis and is subject to change without notice.

What this page is NOT

This page is NOT a status board or health monitor of the OSG sites. Just because your submission fits in with the guidelines here does not mean that your job will start quickly. Nor does it keep track of downtimes at the remote sites. Its sole purpose is to help you avoid submitting jobs with disk/memory/cpu/site combinations that will never work. Limited offsite monitoring is available from https://fifemon.fnal.gov/monitor/dashboard/db/offsite-monitoring

Organization

The following table lists the available OSG sites, their Glidein_site name (what you should put in the --site option), what experiment(s) the site will support, and finally any known limitations on disk, memory, or CPU.

Important notes and caveats: READ THEM ALL!

NOTE 1: In some cases you may be able to request more than the jobsub defaults and be fine. If you do try a site and put in requirements that exceed the jobsub defaults, sometimes a

jobsub_q --better-analyze --jobid=<your job id>

will give you useful information about why a job doesn't start to run
(i.e. it may recommend lowering the disk or memory requirements to a certain value.) We provide information about the largest successful test we have had for memory if above 2000MB.

NOTE 2: Under supported experiments, "All" means all experiments except for CDF, D0, and LSST. It does include DES and DUNE.

NOTE 3: The estimated maximum lifetime is just an estimate based on a periodic sampling of glidein lifetimes. It may change from time to time and it does NOT take into account any walltime limitations of the local job queues at the site itself. It also does not guarantee that there are resources available at any given moment to start a job with the longest possible lifetime. You can modify your requested lifetime with the --expected-lifetime option.

NOTE 4: Take care to convert approproately when using the --memory switch with units in jobsub_submit. To stay consistent with HTCondor, 1GB = 1024MB in the --memory option, not 1000 MB. So --memory=2GB is really --memory=2048MB, and so on and so forth. Thus if you are trying to structure your submission to fit within a certain constraint, and you are using GB as your units, remember to convert appropriately. All memory numbers on this page are in MB, the default HTCondor memory unit.

NOTE 5: Asking for exactly the estimated maximum time is not a good idea because you can't guarantee that your job will match exactly at the beginning of the glidein lifetime. If you need close to the max time, be sure to ask for slightly under it. Of course, don't ask for the full time if you don't really need it!
