[Pw_forum] Pw_forum Digest, Vol 125, Issue 23

[Ronald Cohen]

I have no serial executable, and have never built one, and it runs fine in parallel (except for this). I fixed the problem by changing:
!REC    IF ( opnd ) CLOSE( UNIT = unit, STATUS = status )
    IF ( opnd ) CLOSE( UNIT = unit )

in qe-6.2.1_fat/PW/src/buffers.f90 

I think the problem, in my case anyway, is that the inquire shows the file existing, but meanwhile another MPI task deletes the file, so then it tries to delete a non-existing file.
