STAR Flow, Chirality and Vorticity PWG

Hi Everyone

Here is an update from Gene regarding the status of the cluster. I Norte that Alma 9 is the replacement for SL7 since it is no longer supported.

Hi,

We are pinched from two sides:

1) Our access to Scientific Linux 7 nodes has been decreased to 1/3rd of the farm because the rest has been transitioned to Alma 9 in November. We are competing with sPHENIX (not a winning battle at the moment) for that third.

2) Our transition to Alma 9 depends upon replacing AFS. That replacement was delivered only a few weeks ago (despite our request for it last winter), and has many tricky nuances to sort through. This is where STAR's efforts are now.

I'm not sure I can give an estimate on the transition at this point. Please be aware that for now, "our" and "we" includes production as well as analyses - essentially all of STAR.

If you see held jobs, I recommend that you try to determine whether that is happening on specific farm nodes and report this to SDCC in an RT ticket. We've already had reports of such "black hole" nodes, but there may be others.

Hope that helps,
-Gene
