I don't have any first-hand experience with Intel MPI, but in
principle it should work. <br>
<br>
Does your MPI compiler produces dynamic executables by default? If
so, can you try leaving your executable/binary unmodified and load
the libdarshan.so library at runtime using the LD_PRELOAD
environment variable, rather than directly linking it to your
application? There is some more detail about this approach on this
page:<br>

I'm trying to get Darshan running on a RedHat/X86_64 cluster with
a few different flavors of MPI available. I'm most recently trying
Intel MPI and gfortran (Intel Compilers didn't seem to work) and
after a fair bit of tweaking, got the executable recompiled with
libdarshan.so successfully linked in. In my job run script, I
verify that libdarshan is linked in and the job runs to
completion; however no output is generated. I also tried setting
DARSHAN_INTERNAL_TIMING=1, but still no output. Should I be able
to use Intel MPI and/or is there a place that documents which MPI
stacks are supported?<br>
