n_mpi_processors

PlasmaCalcs.hookups.eppic.eppic_io_tools.n_mpi_processors(dir='.')

return number of mpi processors used to run the run at this directory.

searches all jobfiles (see find_jobfiles) to determine number of processors,

from line like “MPI STARTING N PROCESSORS” with N an integer.

if result is ambiguous (different N from multiple places), raise a FileContentsConflictError.

if no jobfiles found, raise FileNotFoundError.

if some jobfiles found but none tell us how many processors were used, raise FileContentsMissingError.
