Is it safe to have multiple jobs output epsilon.h5 into the same directory? Can the epsilon.h5 output be disabled?

Hi,

I'm running an MPB script multiple times in parallel, using different
parameters, but always outputting in the same common directory (writing
results to separate files).
This means a single epsilon.h5 file gets written to by multiple jobs.

It seems to work fine so far, except for a few crashes, which I now
attribute to this simultaneous writing.

Do MPB runs still use the epsilon.h5 file once it has been written or
not? i.e. could one job affect the results of another one due to
changing the epsilon.h5 file?

Otherwise, is there a way to disable the epsilon.h5 output or specify a
different filename/directory?

Regards,
Mike
