#1976: CarpetIOHDF5: add option to have one output file per process -------------------------+-------------------------------------------------- Reporter: rhaas | Owner: eschnett Type: enhancement | Status: new Priority: major | Milestone: Component: Carpet | Version: development version Keywords: | -------------------------+-------------------------------------------------- This is useful when running on systems where many files slow down file access (ie lustre file systems) and where there are many hdf5 output files per MPI rank.
The code combines all output into a file $parfile.h5 which is currently hard-coded.
