The Daily Bulletin

A number of users have reported problems running jobs on Cheyenne recently as a result of loading environment modules by including the commands in their personalized start files (.bashrc, .cshrc, .kshrc, .tcshrc, .login, .profile, and so on).

As advised in our Personalizing start files documentation, Cheyenne users should not set environment modules in their start files. This means not using commands such as:

  • module load nco

  • module load netcdf

Please contact the CISL Consulting Services Group if you have questions.

Batch jobs running on the Cheyenne systems sometimes fail when they create large stdout or stderr files that overflow the spool directory on the first compute node used. Failures from this condition are more likely with MPI jobs. To avoid the problem, CISL recommends redirecting job output to a file as described in this newly updated documentation regarding job scripts.
