Major system updates coming for Geyser, Caldera and GLADE

May 2, 2018

Plans are under way to implement major system updates to Geyser, Caldera and the GLADE file system in June. The Geyser and Caldera clusters’ operating systems will be upgraded to CentOS 7, and GLADE will be upgraded to a new version of GPFS.

Users will need to recompile their executables to run on Geyser and Caldera. Job scripts may need to be updated to run in the CentOS 7 environment as version numbers of most software on the systems will be different.

CISL has begun building all of the required system software such as compilers, the module environment, and critical libraries including NetCDF, MATLAB and IDL. Once those tasks are completed later this month, several Geyser and Caldera CentOS 7 nodes will be made available for users to begin testing and rebuilding their applications.

GLADE will be upgraded to GPFS version 5.0, which will provide improved stability, performance and maintainability. This upgrade will not require users to make any changes.

Updates and more details, including target dates, will be posted in the Daily Bulletin as they become available.
