Message 29153 - Posted: 10 Mar 2017, 8:23:08 UTC

The current ATLAS tasks are the same as the tasks running on ATLAS@Home. We are preparing a new set of tasks with new ATLAS software which require making a new version of the app with a new image. These new tasks will only run on LHC@Home and after the old tasks finish on ATLAS@Home we will not submit any more there.

In order to prepare for the new version we are draining the current ATLAS tasks here. I will post another message when the new version and tasks are ready. At this point I would encourage people to move over to LHC@Home (as a reminder, the ATLAS@Home credit will be migrated here once all ATLAS tasks are done).

Message 29154 - Posted: 10 Mar 2017, 8:37:07 UTC

- Will the subproject status change from "beta" to "production"?
- Will the initial download size be reduced for the new batch (sorry that I ask this over and over again)?

Yes, if everything works properly

- Will the initial download size be reduced for the new batch (sorry that I ask this over and over again)?


No (sorry), but the tasks will run for longer - they will process 100 events instead of 50 events so your overall download traffic will be lower.

Will the console of the new ATLAS-version be more informative.
Now we only see: localhost login

It would be nice to have the "top" command in the Console and the progress of the events processed.

Yes, please.

Also, has suspend/resume been tested on this? For me jobs need to survive the
host being shut down for >12h. Ideally without losing work in progress but definitely without generating spurious errors.

Shure not, but Atlas doesn't have any problems with pausing / suspending / for a longer intervall.

Perhaps you mixed this up with CMS ?

Ok, I get the message :)

I did try recently to run "top" on one of the consoles but it didn't work and I couldn't figure out why. I will try again to make it work.

Well, CMS is certainly worse than Theory in this respect, perhaps because the tasks last longer, but both leave much to be desired; so I've largely given up on CMS now. Hopefully Atlas will be better... shame about the native version.
