<div>Hi</div>
<div> </div>
<div>I am trying to make MUMPS run with MPICH2. I send a mail to MUMPS mailing list but <span class="goog-spellcheck-word" style="BACKGROUND: yellow">couldn't</span> get an answer. </div>
<div> </div>
<div><span class="goog-spellcheck-word" style="BACKGROUND: yellow">MPI</span> stops and gives the <span class="goog-spellcheck-word" style="BACKGROUND: yellow">following</span> error message after a cal to <span class="goog-spellcheck-word" style="BACKGROUND: yellow">MPI</span>_<span class="goog-spellcheck-word" style="BACKGROUND: yellow">BCAST</span></div>
<div> </div>
<div>Here <span class="goog-spellcheck-word" style="BACKGROUND: yellow">NRHS</span> is 0 and COMM is <font size="2"><span class="goog-spellcheck-word" style="BACKGROUND: yellow">MPI</span>_COMM_WORLD (I don't know if running the program with <span class="goog-spellcheck-word" style="BACKGROUND: yellow">mpiexec</span> changes these parameters but the error message does not change.)</font></div>
