Dear community, i have installed Meep using the miniconda3 prebuild version and created a parallel environment via the conda create -n pmp -c conda-forge pymeep=*=mpi_mpich_* command line. I have not installed hdf5 or anything else separately, just the miniconda3 prebuild. My question now is whether i still have to configure hdf5 for parallel usage to get full use of parallel meep or is this directly done by miniconda3. If i run parallel simulations with about 64 cores they seem to work, but they are slower than I expected (~1.5 days in comparison to ~ 8 day with 4 cores...).
Thanks in advance for your help. Best S
