Dear All,
I am trying to do a gw calculations on MoTe2 unit cell. I am using the latest version of code from svn (Version 4.0.3 Revision 103). The GW calculation is crashing giving an error "Fatal error in PMPI_Barrier: Invalid communicator, error stack: " I have attached the necessary files in the zip file. The same input files run perfectly with the previous version "Version 4.0.2 Revision 96". Will it be possible to let me know where am I doing wrong with the new version ?
Best Regards
Soumyajyoti

Dear Soumyajyoti,
thank you for reporting.
Not sure if this solves the issue, but by mistake I've uploaded a version which I was testing (103) instead of the correct one (104).
Could you please do "svn up" (i.e. rev 104) and let us know if the problem is still there ?
Kind regards,
D.

Ok.
Then I would need more info to try to spot the problem. The best thing would be to reproduce it on a smaller DB, running on fewer processor. Could you try something like a 6x6 grid, running on 8 processors ("2 2 2" in input), even if results would be non physical.
Thank you again for reporting the problem.
Best,
D.

It is a good news that you are able to reproduce the error on the smaller run.
Unfortunately I tried and I did not get your error.
A stupid question: did you try to do make clean_all before recompiling the code after the "svn up" ?
Meanwhile I will go on inspecting the problem.
Best,
D.

Dear Davide,
Yes I did make clean_all before configuring again.
I'll try to install in a different computer and will see if I can reproduce the error.

I am having the same error as above using yambo 4.0.3 rev104,
"Fatal error in PMPI_Barrier: Invalid communicator, error stack:"
Previous version of yambo (4.0.2 rev 90)did not give this error.
I have noticed that the configure options of yambo 4.0.3rev104 lacks "--with-blacs-libs" and "--with-scalapack-libs".
Would this be relevant to the above error? Were these options deleted on purpose?
