You’ve found the wrong mailing list for this question. This mailing list is for those working on writing the MPI Standard, not for bug reports, questions, etc. You’ll need to ask this question on the mailing list of the implementation you’re using.

This requires configure this option at the set up step : ./configure --with-ft=cr --enable-crdebug But no matter which version of Open MPI, I can't not find any option as --enable-crdebug (I have tried all versions from 1.5 to the newest one 1.8.1).

I appreciate all your helps and thanks all. -- Đỗ Mai Anh Tú - Student ID 51104066 Department of Computer Engineering Faculty of Computer Science and Engineering HCMC University of Technology.
