Hi all,<br><br>I have a implementation with the following problem:<br>During the execution, it is possible that some process find an error and, in this case, the whole execution must be aborted. So far, I have been using the MPI_ABORT function, but there is some stuff that the processes must do before stop and the MPI_ABORT function doesn't return the control to its calling function.<br>
<br>The only way I can see now is to fill the code with check-points to verify if the computation can continue or create a group/communicator with all the processes excepting the one that found the error and abort this group...<br>
<br>Is there a better way to implement such kind of behavior?<br>Is there any kind of callback that returns the control to an user function in case of an abort is needed?<br><br>Thanks,<br>LC<br>
