<br>
I compiled PETSc with Intel MPI (MPICH) and GCC as compiler (i.e. using<br>
Intel OneAPI together with the supplied mpicxx-compiler). Compilation<br>
and installation worked fine, but running the tests resulted in the<br>
error "Attempting to use an MPI routine before initializing MPICH". A<br>
simple test program (attached) worked fine with the same combination.<br>
<br>
What could be the reason for that?<br></blockquote><div><br></div><div>Hi Roland,</div><div><br></div><div>Can you get a stack trace for this error using the debugger?</div><div><br></div><div> Thanks,</div><div><br></div><div> Matt</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
