Fix parallel phsp source partition #1126

Commits on Aug 9, 2024

  1. Fix phsp source partitionng for parallel runs 

    This fix divides phase space sources used in parallel runs into
npar*nchunk equal segments, where npar is the number of parallel runs
and nchunk is the number of chunks (defaults to 10). Each chunk of the
parallel run is then assigned its own segment of the phase space source
outside of which it will not sample. This scheme, identical to that used
in the EGSnrc mortran codes, should ensure relatively even sampling of
the phase space source over the entire parallel run.

  2. Handle histories left at end of parallel job 

    Any remaining histories after completion of npar*nchunk simulations
chunks reuse particles from the last segment of the phase space file.
