<P>When debugging in parallel you will need to start the job without gdb and
then connect individually to each of the pvserver processes with
gdb.</P>
<P>The other option is to use a parallel debugger such as DDT or totalview -
both are commercial but you can get a trial license. Note: I'm biased towards
DDT as I used to work for Allinea and was one of the original developers!</P>
