I am using PVM 3.3.3 on an SP2.  When I try to use Direct Routing :

       call pvmfsetopt(PvmRoute,PvmRouteDirect,iOldValue)
       write(*,*) 'Direct Routing',pvm_me,ioldvalue

the program screws up when sending some large messages.  If I try the 
supposedly default setting 

       call pvmfsetopt(PvmRoute,PvmAllowDirect,iOldValue)
       write(*,*) 'Allow Direct Routing',pvm_me,ioldvalue

the program *really* enjoys it and becomes a large NaN generator. 
If I give up and comment out the lines, the program runs fine.  

My question is: 'Does Direct Routing work on the SP2, and if so, how
                 can I get it to work?'

If it doesn't work, I'll just comment out the lines and go my 
merry way. :)   Thanks in advance for any help.

Paul
