<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I am using MPICH2 on a Beowulf cluster, and I am
trouble setting breakpoints.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>This is a typical interaction I have with
gdb:</FONT></DIV>

<DIV><FONT face=Arial size=2>The problem is that although I set the breakpoint,

<DIV><FONT face=Arial size=2>Any ideas what I am doing wrong?</FONT></DIV>
