Subject: | New operating system default in HTC system, October 17; please read |
Greetings CHTC users, This message is for all users of our high throughput computing (HTC) system. CHTC staff are continuing to upgrade the computers in our HTC system to a newer version of Linux, as described in this guide. Up to now, HTC jobs submitted from CHTC-managed submit servers have required (by default) that they only run on execute servers with our Scientific Linux 6 operating system. Users have been able to also run on our newer operating system (CentOS 7) by opting in as we transition more execute servers to this new version. In two weeks, this default will change. On October 17, all CHTC submit servers will be configured to allow submitted jobs to run on either operating system version unless you specify that they require only one of these. CHTC jobs that have been running on Scientific Linux 6 will also be able to run on the newer CentOS 7 without errors (based upon our own tests and the experiences of users who have tried running on the newer CentOS 7). We anticipate that most users should be able to continue submitting jobs as usual without any changes.If you are interested in testing your jobs on the new operating system (just to make sure they'll work), or if you otherwise know that your jobs cannot run on both operating systems, read on:
If you experience a situation where code that you've compiled on our Scientific Linux 6 servers (the current default) fails when running on CentOS 7 servers, please let us know immediately! Email questions or concerns to chtc@xxxxxxxxxxx. Best, Your CHTC team |
