JobSub Releases

Tasks Before Release

  • Unit test new features & bug fixes
  • Before a final release, one or more RC (release candidate) are released.
    • RCs undergo integration testing on the development servers by the development team. ** documentation on current Integration_Test_Suite * After the development team is satisfied with their level of testing, GCSO (operations group) deploys the software on the pre-production machines to perform additional testing.
  • After the release
    • Send release announcement to <mailing list> * Open a ticket with GCSO to install new version on pre prod for wider testing

Release Schedule

JobSub releases are made once the features/bug fixes charted for a given release are tested. In addition to that there could be an emergency release made to address critical issues and/or bugs.

Visit the issue tracker https://cdcvs.fnal.gov/redmine/projects/jobsub/issues if you are interested in issues addressed in future releases. Click on the filters (Custom Queries) to the right of the page to look for features in a given release.

Client User Guide

Jobsub services on fifebatch infrastructure

Old Submission Model (jobsub_tools) v/s New Model (jobsub_client)

The previous jobsub_tools client took input arguments and generated a condor job description file (jdf) on to a shared disk between the client and server . It then ssh'ed to the server and executed a condor_submit. This architecture is beginning to reach the limits of its scalability.

The new client does not share disk mounts with its server. Given a couple of extra arguments as compared to the old client, it contacts the server through a REST API and passes the arguments through. The server then uses the 'old' jobsub to generate the condor jdf and perform a condor submit. Log, error, and stdout files are written to a local directory on the server machine, and can be retrieved using jobsub_fetchlog.py as documented below or via curl. Authentication to the new server is done vi kx509 certs using the 'getcert' utility which comes with all Fermi Scientific Linux installations.

Job id Syntax

Longtime jobsub and/or condor users are familiar with the condor job id for thier jobs, which look like a floating point number i.e. my submitted job is number '19332.0' in the queue. The jobsub_client submits to a DNS alias which can have a number of physical jobsub servers behind it. To avoid confusion the returned job id will be of the form 'job_number@schedd_name.', i.e. ''

JobSub Server

JobSub Client

Supported Platforms

Linux is the only officially supported platform. The client might still work on Mac OSX, may be missing some functionality and is for more adventurous users!

JobSub Client Dependencies

JobSub client depends on following to be installed/available in the machine

  • *Submission Credentials
    • A valid x509 proxy or cert/key pair that identifies with the VOMS server is required. You currently have two options for generating a valid proxy:
    • Option 1: generate a proxy from a valid kerberos ticket. Use kinit and then kx509 to generate a proxy.
    • Option 2: use cigetcert to generate a proxy using using your Fermilab Services Account name/password.
    • Other institutions will be able to authenticate and submit jobs authenticating with cigetcert soon. Details will be linked to when available
  • Software Dependency
    • pycurl
    • On Linux SL5: available in KITS, i.e. source /cvmfs/fermilab.opensciencegrid.org/products/common/etc/setups ; setup pycurl ** To install pycurl so it is automatically set up prior to jobsub_client install it as 'current' with one of the following incantations, depending on which OS/Pycurl version you are setting up for. ** Doing both incantations should not harm anything, 'setup jobsub_client' should pick the right one at set up time: ** upd install -G "-c" pycurl v7_15_5 -H Linux64bit+2.6-2.5 ** upd install -G "-c" pycurl v7_16_4 -H Linux64bit+2.6-2.12 * On Linux SL6: should be part of your python distribution. If not, yum install pycurl
    • kx509: Software to generate x509 proxy from kerberos ticket.
    • Fermilab is in the process of switching Certificate providers from Digicert Corporation to Cilogon Corporation. This process started about 6/1/16 and will be completed by 1/1/17, at which time Digicert proxies and the 'old' kx509 will not work.
    • Kx509 (Cilogon) is available via fermilab-util_kx509.noarch rpm. Yum install -y fermilab-util_kx509
    • Non-Expert User:
    • Option 1: source /cvmfs/fermilab.opensciencegrid.org/products/common/etc/setups; setup jobsub_client
    • Option 2: For FEF/GCO managed machines, open a SNOW ticket to get the above software installed.
