Hi [name removed],

I just installed the V8P4 by using the automatic package. However, when I would like to use the parallel simulating (MPI), I got an error. Please see the attached photo and give me some advices. Thank you so much.

Hi

Probably an illegal character in you steering file…

Hard to say more but you could try with a lighter version without any comments to check…
