Hello everyone,<br>
<br>
I am solving complex Ax=b with PaStix on 20 processors successfully<br>
but failed on 24 processors. The relatively error indicated by<br>
mat_pastix_verbose becomes "nan" for 24 processors. Where could be<br>
wrong? Can someone give me some hints on how I can debug? Thanks.</blockquote><div><br></div><div>First, make sure you did not put any NaNs in your matrix or rhs.</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">
