Subject: Re: [OMPI users] Open MPI access the same file in parallel ?
From: David Zhang (solarbikedz_at_[hidden])

Under my programming environment, FORTRAN, it is possible to parallel read
(using native read function instead of MPI's parallel read function).
Although you'll run into problem when you try to parallel write to the same
file.
