Creation of comms.mod is non-deterministic?

[chillenzer]

Hi, I'm playing around with the code again and found that quite regularly compilation via make fails due to

Fatal Error: Cannot open module file 'comms.mod' for reading at (1): No such file or directory

which -- when I look this up -- is correct, i.e. the file is indeed missing. Retrying again usually fails but retrying a few times (maybe sprinkling in some make cleans here and there) seems to do the trick and sooner or later it seems to work out just fine. What's going on there? And more importantly: Any ideas how to fix this?

Looks like an oversight in MkRules—dirac.F90 depends on comms.mod (i.e. it contains use comms), but this dependency is missing in MkRules at line 132.

Thanks for the hint. Should've spotted that myself but in a new code base... BTW, I found a few more of these. Now, it's compiling like a charm except for #4 .
