Are you suggestion that I should install a 32b version on all machines because 32b can't *talk* to 64b?<div class="gmail_extra"><br><br><div class="gmail_quote">2012/12/9 Jeff Hammond <span dir="ltr"><<a href="mailto:jhammond@alcf.anl.gov" target="_blank">jhammond@alcf.anl.gov</a>></span><br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">It appears you're trying to use the 64b library (ELFCLASS64...) on the<br>
32b master. In any case, I don't believe MPICH works in the<br>
heterogeneous case. In theory, you should be able to use a 32b<br>
library across both machines though.<br>
