The LAMMPS 14May16 known issue wherein parallel lammps spawned too many threads has been fixed on all clusters.  No user action is required; if a user had applied the OMP_NUM_THREADS workaround then it may be removed, but it will not cause probems if left in place. The corrected executables were made the defaults for module lammps/14may16 at these times:

All ACLs lost in Home Directories after 6/7 downtime

Date: 
Tuesday, June 7, 2016 - 6:00pm
Supercomputer: 

All ACLs set within the Home Directory filesystem (/nfs/##) were lost during the 6/7 downtime.  This was caused by the migration to a new server that does not support the old POSIX ACLs.

Migrating the ACLs was not possible due to both the fact POSIX ACLs are not easily translatable to NFSv4 ACLs, and none of our tools supported such a migration.

Max core and parallel job limits reduced

Date: 
Tuesday, April 26, 2016 - 3:15pm
Supercomputer: 

In order to allow for a more equal distribution of resources amongst our community, the limit on the maximum cores in use by a user and by a group have both been temporarily reduced from 2040 cores to 1500 cores.

The max size of a parallel job has also been reduced from 170 nodes to 125 nodes.
