Porting a UM Suite to ARCHER2


Rose/Cylc Suites

Unfortunately as UM suites can be configured in many ways and there’s no “standard” UM suite configurations it is difficult to provide a comprehensive set of porting instructions. We provide a “quick start” guide which should be appropriate to most UM11.x versions and then further detailed guidance covering changes to the suite *.rc for the move to the SLURM Scheduler.

Table 1. Note, for example, u-be303/archer2 indicates the archer2 branch of u-be303.


Only UMUI versions 7.3 and 8.4 are supported on ARCHER2.

Note: Only the small executables pumf and cumf have been built to run on ARCHER2.

CMS have ported 2 standard jobs to ARCHER2:
