Cheyenne users urged to report system problems

August 20, 2019

The number of known Cheyenne job failures has decreased significantly since we adjusted several system parameters on August 10, but CISL staff continue to work with HPE, Mellanox, and IBM Level-3 support teams to resolve some remaining performance issues. Please continue to report problems to cislhelp@ucar.edu, especially slow GLADE response times and jobs that fail with MPI_LAUNCH_TIMEOUT errors. If possible, please include job numbers and the full GLADE pathnames of the job standard error and output files. Thank you to everyone who has reported system problems recently.
