<div class="moz-cite-prefix">Just a quick update on this thread:
there is a pre-release version of Darshan (2.2.8-pre1) available
on the Darshan download page now that includes a fix for the
MPI_Init_thread() problem that Myriam reported.<br>
<br>
2.2.8-pre1 also happens to fix a compatibility problem with MPI-3
(MPICH 3.x to be specific) which may be of interest to some folks
as well. We will turn this into an official 2.2.8 release
relatively soon.<br>
<br>
thanks,<br>

<div class="moz-cite-prefix">Thanks for the bug report Myriam. I
see what you are talking about, it looks like we just forgot to
copy that code over from the MPI_Init() function. We'll test it
out and get the fix committed for the next release.<br>

<div style="direction: ltr;font-family: Tahoma;color:
#000000;font-size: 10pt;">Hi all,<br>
For those who want to use Darshan as a dynamic library with
multithreaded applications, the MPI_Init_thread wrapper is the
issue.<br>
A simple program calling MPI_Init_thread() and MPI_Finalize()
will crash if LD_PRELOAD is set to libdarshan.so<br>
As a workaround - do MPI_Init_thread() call
resolve_mpi_symbols() as it is done for MPI_Init() <br>
Hope it will help <br>
Myriam,<br>
