ANSYS default module changes

Date: 
Monday, February 2, 2015 - 4:15pm
Supercomputer: 

We have updated the default module of ANSYS on both Oakley and Glenn. The default module of ANSYS is ANSYS 14.5.7 on Oakley and ANSYS 14.5 on Glenn. For example, if you use module load ansys on Oakley, ANSYS 14.5.7 (instead of ANSYS 13.0) is loaded. We however keep the older versions of ANSYS installed on our cluster.

We have updated the default module of FLUENT on both Oakley and Glenn. The default module of FLUENT is FLUENT15.0.7 on Oakley and FLUENT 14.5 on Glenn. For example, if you use module load fluent on Oakley, FLUENT 15.0.7 (instead of FLUENT 13.0) is loaded. We however keep the older versions of FLUENT installed on our cluster.

Parallel netCDF

PnetCDF is a library providing high-performance parallel I/O while still maintaining file-format compatibility with  Unidata's NetCDF, specifically the formats of CDF-1 and CDF-2. Although NetCDF supports parallel I/O starting from version 4, the files must be in HDF5 format. PnetCDF is currently the only choice for carrying out parallel I/O on files that are in classic formats (CDF-1 and 2). In addition, PnetCDF supports the CDF-5 file format, an extension of CDF-2, that supports more data types and allows users to define large dimensions, attributes, and variables (>2B elements).

Jobs requesting Lustre are rejected by qsub

Date: 
Friday, August 15, 2014 - 11:30pm
Supercomputer: 

On both production clusters, we have begun rejecting jobs that request the use of Lustre or $PFSDIR in order to reduce job failures caused by the triggering of a bug that crashes the filesystem. If you have a GPFS allocation, you may if appropriate want to move your data there in order to maintain productivity while the Lustre service is in a degraded state.
