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>

<p class="MsoNormal">I have built Darshan using Intel MPI (2017)
and would like to profile a sequential code using Darshan. I
have used the same Darshan library to profile an MPI code it
works fine. I execute the following command line for a
sequential code :<o:p></o:p></p>
