abaqus with UMAT

On Owens, usage of user-defined material (UMAT) script for abaqus is limited as following:

abaqus 2017: correctly running on single and multi-nodes

abaqus 6.14 and 2016: correctly running only on a single node

 

Resolved: We confirmed that this is an issue on the old versions only. The software page indicates this issue. 

libibumad.so.2 missing on Oakley

Update:  We think this is fixed.  Please submit a ticket if you encounter further problems.

 

As a result of updates made during yesterday's downtime, software built with mvapich2/1.7 is failing with the error:

libibumad.so.2: cannot open shared object file: No such file or directory

We're working on fixing the problem.

Problems with LAMMPS 14May16

LAMMPS 14May16 was built with the USER-OMP package on Oakley, Ruby, and Owens. Its default behavior is to spawn too many OpenMP threads. lammps/14May16 batch scripts that do not use the USER-OMP package should set the OMP_NUM_THREADS environment variable to 1 as a workaround, e.g.:
export OMP_NUM_THREADS=1
for Bourne type shells and
setenv OMP_NUM_THREADS 1
for C type shells.

Problems with MVAPICH2

Some MVAPICH2 MPI installations on Oakley, Ruby, and Owens, such as the default module mvapich2/2.2 as well as mvapich2/2.1, appear to have a bug that is triggered by certain programs.  The symptoms are 1) the program hangs or 2) the program fails with an error related to Allreduce or Bcast.

Glenn module lammps-7Dec15 bug

Batch scripts loading module lammps-7Dec15 should use the user's login shell or

the Korn shell, e.g. #PBS -S /bin/ksh

There is a bug that causes the module load to fail if the job script specifies the Bash shell, i.e.: 

#PBS -S /bin/bash

Alternatiely you can unload mpi and intel-10.x before loading the lammps module.

An example failure is:
