We tried to make the most common info_keys the same, but there can be differences. What info keys are you trying to pass?<br><br><br><div class="gmail_quote">2009/8/17 Federico Golfrč Andreasi <span dir="ltr">&lt;<a href="mailto:federico.golfre@gmail.com">federico.golfre@gmail.com</a>&gt;</span><br>
<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Hi!<br><br>I have a little code that uses the MPI_Comm_spawn_multiple, <br>I&#39;ve used it without any problems with the MPICH2 and MVAPICH2 implementation of MPI-2,<br>
but with the Open MPI <span>v1.3.3 it throws this error:<br>
<br>*** An error occurred in MPI_Comm_spawn_multiple<br>*** on communicator MPI_COMM_WORLD<br>*** MPI_ERR_INFO: invalid info object<br>*** MPI_ERRORS_ARE_FATAL (your MPI job will now abort)<br><br>and I&#39;ve seen on <a href="http://www.mpi-forum.org/docs/mpi21-report-bw/node204.htm#Node204" target="_blank">http://www.mpi-forum.org/docs/mpi21-report-bw/node204.htm#Node204</a><br>

that the MPI_Info object keys depend on the implementation.<br><br>Does the OpenMPI have a different implementation in respect of the MPICH/MVAPICH?<br>What I have to change in order to make it run?<br>Or the problem is elsewhere located?<br>

<br>Thank you very much,<br>   Federico Golfrč Andreasi<br></span><br><br>
