Yes, adding MPI_INIT & MPI_FINALIZE to your code should allow
you to generate Darshan logs fine. Let us know if you have any
issues.<br>

<p class="MsoNormal" style="margin-bottom:12.0pt">Hi Wadud,<br>
<br>
Right now, Darshan can only instrument MPI applications. It
intercepts MPI_Init and MPI_Finalize to initialize itself and
to produce the output log file, respectively. It also uses MPI
communication and I/O operations at shutdown time to aggregate
data across all processes and write to the log file. Breaking
the MPI dependencies isn't exactly straightforward, but we
have at least been thinking about how to extend Darshan to
non-MPI codes. Recent changes to the architecture have been a
step in the right direction but there's still work to do to
get us all the way there.<br>
<br>
We will continue to think about this and will certainly keep
the mailing list updated with any progress we make.<br>
<br>
Thanks,<br>
