Comment (by hinder):

 There is something wrong; the output says that the evolution is running on
 6 MPI processes, and your ini file says that you want 10 threads per
 process, but I can see 6 processes on the first node.  Can you describe
 exactly how your "HPC" is set up?  It sounds like you have 7 nodes, one
 "master" and 6 "slaves".  How many processors, and how many cores, does
 each node have?  Are you intending to run using OpenMP + MPI, or pure MPI?
