Testing CentOS 7 on Pegasus

On Feb 12th at 5pm Pegasus compute nodes in the parallel, general and bigmem queues will be updated to CentOS 7.

We encourage you to test your applications on CentOS 7 prior to the update.

On Pegasus, a queue named ‘centos7’ has been created. You may submit jobs to this queue for the purpose of testing and validation on CentOS 7 prior to the scheduled upgrade.

Important

As a courtesy to others, please do not run jobs for more than 24 hours or use more than 64 cores in the centos7 queue.

Important

The share-rpms65 module conflicts with CentOS 7. You must be sure to remove the share-rpms65 module from your .bashrc or .cshrc prior to login on the centos7 headnode if you are currently using this module.

To submit jobs to the centos7 queue you must first login to pegasus as usual:

% ssh ccsuserid@pegasus.ccs.miami.edu

Then connect to the new head node:

% ssh centos7test

Here, you can submit jobs to centos7 test queue:

-bash-4.2$ bsub -q centos7 -P myprojectname -Is /bin/bash

Please contact us at hpc@ccs.miami.edu to report any problems.
