<h4 style="font-weight: normal; font-family: arial,sans-serif;">Hi everyone,</h4><span style="font-family: arial,sans-serif;">I am trying to run a program I wrote myself using mpi. The basic idea is to dispatch tasks in the program on serveral cores/computers. It works fine (i.e. the results of the tasks are correct and well collected). However I have an error after the finalize (during...?). Anyway the "Exiting program" is after the instruction finalize (and only done by the master).</span><br style="font-family: arial,sans-serif;">
<span style="font-family: arial,sans-serif;">I have not been able to find what was causing this error. The message is below. Note that the error is not deterministic (i.e it does not happen all the time...). If someone has any begining of idea I would be grateful to hear it.<br>
<br>Another question : is there a friendly gpl (or at least free) mpi debugger ?<br><br>Thanks in advance for your help<br><br>Quentin<br style="font-family: verdana,sans-serif;"></span><br style="font-family: arial,sans-serif;">
