I am trying to debug my CFD Fortran MPI code. I tried to add:<br>
<br>
call PetscBarrier(PETSC_NULL_OBJECT); if (myid==0) print *, "xx"<br>
<br>
to do a rough check on where the error is. xx is a different number for each line.<br>
<br>
I found that whenever I add this line, the code aborts with segmentation error.<br>
<br>
I am using the Intel compiler. Is there any error with my usage?</blockquote><div><br></div><div>I don't think this makes sense since it will try to pull a communicator out of the NULL_OBJECT.</div><div><br></div><div> Matt</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span class="HOEnZb"><font color="#888888"><br>
