in case of serial x and y directions (i.e. PARFFTX=false, PARFFTY=false) and parallel z direction (i.e. PARFFTT=true). The simulation that was ran is psiring.in. The fieldmaps can be found in the repository AMAS-BDModels / PSI-Ring. Following modules were used for running on Merlin:
module use unstable
module add gcc/5.4.0
module add openmpi/1.10.4
module add hdf5/1.8.18
module add H5hut/2.0.0rc3
module add trilinos/12.10.1
module add gsl/2.2.1
module add boost/1.62.0
When changing to parallel x, y and serial z, i.e. PARFFTX=true, PARFFTY=true and PARFFTT=false) no error occurs.
