Upcoming Tier-3 Changes (Monday 11 March)

Next Monday there will be some minor user-facing changes to the Tier-3.
We will be migrating into the SDCC shared pool, which means your jobs
will have access to many more resources (upwards of 25,000 CPU cores).
The pool is configured with partitionable slots, which means jobs can
request as many CPUs and as much RAM as they need. The default request
is 1.5Gb/core (use "request_memory" in your jobs to ask for different).
Furthermore, accounting groups no longer need to be put in your jobs (in
fact if you do they will be ignored). Condor will automatically classify
you based on your institution. Running "whatgroup" will still show your
institution. If you are new and haven't been assigned yet you will be
classified into the "general" group and a warning will be printed.
The documentation has been updated to reflect this -- see here:
(some of the above does not apply to the tier-3, but much does)
On the morning of March 11, we will disable submission for around an
hour as these changes are implemented. I will send out one further
announcement closer to that date. Any questions please send an RT ticket
or a reply to the list if it is a question that may affect other users
-- I will try to monitor the list more closely for now.
