Shock-carc configuration
From SCECpedia
This page documents the configuration requirements for shock-carc.usc.edu, which will be used as a workflow submission host for CyberShake.
Contents
Functionality
Once shock-carc is fully configured, we would like to be able to:
- Have users on SCEC projects and the Pegasus team be able to log into shock-carc.
- Submit remote Condor jobs to Summit.
- Submit remote Condor jobs to Frontera.
- Create, plan, and run a Pegasus workflow, which interacts with CyberShake databases.
Hardware
- In addition to internal disk, 2 TB of local storage (preferred, but not required)
Software (installed by CARC)
- Linux OS (whatever default flavor CARC prefers is fine - CentOS 7)
- HTCondor (9.0.1, out in mid-May)
- MariaDB (repo has 10.5.5). MySQL is also fine.
- globus-url-copy (should be available in Extra Packages for Enterprise Linux (EPEL))
- sqlite3, if not part of the OS
- screen, if not part of the OS
- ImageMagick, if not part of the OS
- Java 11 (11.0.11 is the latest)
Software (installed by SCEC)
- Pegasus will be installed by SCEC developers in user space, since we often build from source.
- OpenSHA will be installed by SCEC developers in user space.
Configuration
- HTCondor configuration is specified through two configuration files, condor_config and condor_config.local. CARC, the Pegasus team, and SCEC developers will work together to correctly set up these files. We anticipate that condor_config will be owned by user condor and thus require CARC to edit, but that condor_config.local will be owned by user scottcal.
- For MariaDB, permissions should be set up by CARC so that users can create and write to databases. Access to these databases should be restricted to localhost.
- To enable remote job submission, we request that CARC adds whitelisting exceptions for a short list of OLCF and TACC nodes, which will be provided separately.
- Certificate? Not required.
