Bell Maintenance Test Environment Available to Users
As part of Bell's maintenance on March 4-5, we will be upgrading the operating system from CentOS 7 to Rocky Linux 8, which requires us to rebuild the applications hosted on Bell. As part of this application rebuild, we will be removing old and unused versions of our applications and upgrading many of them to newer versions.
In order to aid in that transition, we have made a test environment available to users so they can begin rebuilding their applications under the new toolchains and exploring the new software stack. We expect that this environment will not change much ahead of the maintenance next week, but we may end up making small changes to the application stack before then.
This test environment can be accessed by using the combination Slurm options -A debug --reservation=rocky8test in your current job submission with sbatch or sinteractive from any Bell’s front end nodes. This will make sure to submit to test nodes. Wait times may be larger for these test nodes due to their only being a limited number of nodes available for testing. The limitation on the debug queue is: 1 concurrent running job and 4 job submissions for each user with a 30-minute’s max walltime.
If you encounter issues or have questions about this maintenance, please reach out to us at rcac-help@purdue.edu.
