There are two example SWIFT mpi logging output logs. A small one for checking
program developments and a larger one that exhibits the unwanted behaviour on
the COSMA7 cluster.

The small dataset: `EAGLE_6-mpiuse_report-step2-4ranks-small-step.dat`, is the
second step of a 4 rank run of the EAGLE_6 low z example.

The larger dataset: `EAGLE_25-mpiuse_report-step18302-16ranks-inter-step.dat`,
uses the high z EAGLE_25 with 16 ranks. Decompresses to 21M.
