[Darshan-users] Darshan and Intel MPI (x86_64)

[Phil Carns]

I don't have any first-hand experience with Intel MPI, but in principle 
it should work.

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:

thanks,
-Phil
