Analysis cloud and batch computing

We are sharing the General Physics Computing Facility (GPCF) with other experiments. Information on running batch jobs on GPCF is provided by the support group. You can submit batch jobs from seaquestgpvm02.

The SeaQuest TWiki provides collaboratively edited and interlinked documentation. You can register yourself for the TWiki but you have to ask a registered member to add you to the E906 TWiki group.

Tutorials, guides, references, and meeting presentations are available on the SeaQuest DocDB. We encourage you to use certificate access to access the SeaQuest DocDB and suggest to request an Open Science Grid (OSG) certificate that needs to be renewed only once per year. The instructions for getting a personal OSG certificate are simple and given in the section. When you have imported your OSG certificate, just complete this form and you can use certificate access for the SeaQuest DocDB.

Open Science Grid certificate

Instructions for obtaining your Open Science Grid certificate (valid for one year):

  1. Import the OSG CA certificates into your browser: The CA certificates are available at the DigiCert-Grid Repository. The section titled "DigiCert-Grid Grid-Only Trust CAs" contains the information and links for the Certificate Authority for issuing the OSG PKI certificates. To import the OSG CA certificates into your browser, download both the Root and CA-1 in PEM format files and then go into the Certificate Manager of your browser and use the Import function In Mac OS X, certificates are handled by the Keychain Access application. Make sure your import these certificates as Authorities. Note that the OSG CA trust chain for your personal certificate requires both the Root and CA-1 CA certiticates.
  2. Request your personal OSG certificate: Please fill out the form at OIM User Certificate Request to obtain a personal certificate from the OSG PKI. The name of our Virtual Organization is SeaQuest. Please select Dave Christian, Markus Diefenthaler, or Paul Reimer as sponsor for your OSG certificate.
  3. Import your personal OSG certificate into your browser(s): You will receive an email message from OSG PKI stating whether your request was approved or denied. The OSG personal certificate will be delivered to you from OSG in a .p12 file (also known as a .pfx file) which is a PKCS#12 format binary, multi-part file. The file from OSG contains both your personal certificate and your private key (hence the need for secure storage of your .p12 files). Please go into the Certificate Manager of your browser and use the Import function. In Mac OS X, certificates are handled by the Keychain Access application.


We use Redmine mainly due to its version control support. But various working groups make use of the various other features of the web-based project management and bug-tracking tool. We will maintain a list of our Redmine projects. Please use the seaquest-help mailing list to request a Redmine project for your software projects or for organizing your own source code. Documentation on working with the Redmine Git repositories and Redmine Wiki are available.

Shift business

We use the ELOG weblog to document our work on the experiment and to log the data taking. Please register for the ELOG and note that your registration needs to be approved. This typically happens within less than a day.

Please also create an account for our shift calendar. Detailed documentation on using our shift calendar is available on the SeaQuest DocDB.
