NCAR Mesa Lab power down on April 13

April 9, 2019

A semi-annual NCAR Mesa Lab building maintenance power-down is scheduled for Saturday, April 13, but it should have little impact on university users of CISL’s high-end resources. Some Boulder-based UCAR/NCAR staff will be unable to log in to the Cheyenne system or other services, but sessions that start before the power-down will not be affected. The maintenance work is scheduled to begin at 4 a.m. and conclude by early evening.

The Cheyenne and Casper clusters, the GLADE system, Campaign Storage, and HPSS will remain in service at the NCAR-Wyoming Supercomputing Center (NWSC) in Cheyenne. Services that will be unavailable during the power-down include the SAM accounting system, the CISL website, license servers for Mathematica and the PGI compilers, and the ExtraView help desk ticketing system. The license server that supports MATLAB users on Cheyenne will not be affected.

Users who have urgent help requests during this time should call 303-497-2400 or 307-996-4300 to reach the NWSC operations center.
