Hi, Firedrake is now available on Archer via the central system module 'firedrake'. To run Firedrake on the compute nodes please add the following to your .pbs file: module swap PrgEnv-cray PrgEnv-gnu module load anaconda module add firedrake and run your firedrake model with: aprun python my_firedrake_model.py Due to a known problem, Firedrake currently needs to be initialised in my_firedrake_model.py with: import pyop2 from firedrake import * If you have access to AUs on Archer, please give this a try and report any further problems you encounter. Thanks, Michael
