Summary information for Hoffmann

...

Recap:

During our recent test period of Sol in November, researchers confirmed that the new system's hardware and base configuration fully enables the proper functioning of all the software they currently depend on within Helios.

However, the testing also uncovered important information that we could not have learned without this testing investment, which in turn will contribute to a more robust setup for researchers. For example, Lulu has installed the Intel compiler in the /software/ directory, with the proper, legal licensing.

Upcoming to do's for Hoffmann researchers, as of 12/9/13:

...

researchers, as of 12/11/13:

Sol and Helios will be unavailable to researchers between Monday, Jan. 6th at 9am and approximately Thursday, Jan 9th, at noon.

• Before the shutdown, all data of value must be copied off of Sol.
  • All user directory data will be removed.
• Before the shutdown, all jobs on both Sol and Helios must be stopped.
  • Any remaining jobs will be stopped by ChemIT staff

Detailed information for cluster migration:

1) Reduce the amount of researchers' temporary, test user data on Sol

...

to the bare minimum during the break.

• After the break, ChemIT will be deleting the content within everyone's test home directories on Sol. (They Those directories were originally copied there as a testing convenience during our test phase.)
  • We do this deletion before the final copy to ensure a clean import of researchers' current production home directories from Helios.
  • Lulu advised researchers of this step before the Thanksgiving break, so hopefully no surprises.

Bottom line: If there are any files on Sol which researchers cannot afford to lose (hopefully not- it was in test mode, and it is not being backed up!), researchers must move that data to Helios (or elsewhere) right away.

2) On a predetermined date, researchers will stop having access to Sol until it goes into production, replacing Helios.

before Sol is turned off.

QUESTION: What backup will Sol have during the winter break? Versioning? EZ-Backup? Both?

2) Monday, Jan. 6th at 9am: Sol AND Helios being turned off to researchers

• ALL jobs must cease by then, or they will be turned off by ChemIT.
• Also, there must be no remaining research data on Sol.

3) Thursday, Jan 9th, at noon: Expect Sol available to researchers.

• At this point, Sol will be up in full production and open to all researchers, with some or all of Helios's compute nodes attachedTasks for ChemIT to do:
• Get the server's versioning hard disk recognized within the new head node.
Ensure central software is installed properly and legal.

3) On a predetermined date, researchers must plan for 1-2 days of downtime for Helios (and before Sol is available).
