<P><FONT SIZE=2 FACE="Arial">Hi</FONT>
<BR><FONT SIZE=2 FACE="Arial">I am encountering what I think are two unrelated problems when trying to run a large POPE membrane.</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">1. Whenever I use hbonds constraints, compilation (i.e. grompp) isn’t successful when trying to prepare it for more than 2 cpus.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">2. When I run it without any constrains the runs crash after several thousand steps when using more than 2 CPUs. I does however run fine on just 2 CPUs.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">Any ideas?</FONT>
</P>
