Several of the UKCA Release Jobs have been ported from HECToR to ARCHER, and their jobids are detailed on that page.
Timings
The plot shows how UKCA scales when ported to ARCHER. The most efficient number of nodes to use is 3 (8x9), although the model will run fastest on 6 nodes (e.g. 16x9 or 12x12). Moving to 3 nodes from 6 will increase the run-time by 50%.
Code Changes
Cray cce Fortran Compiler
Corrections required for the Cray cce compiler on archer can be found on the bugfixes page.
