[mpich-discuss] ddd + mpich2

[Burlen Loring]

Hi Robert,

Thanks but, that is not what I am looking for.  if I am not mistaken, 
what you suggest will start 8 ddd's and to get my app up and running I 
will have to type a run command in each of 8 processes. On the other 
hand...The mpich2 "mpiexec -gdb" has the nice feature you have a single 
gdb session that interacts with all of the processes. Using mpich2's 
"special" gdb you can set break points on all with a single command, or 
select specific processes to issues commands to. Would be very nice if 
somehow ddd could be pointed to mpich2's gdb so that single instance of 
ddd can interact with all of the processes...

Do you know how mpich2 accomplishes this stuff? I wonder if it is part 
of mpd or if there is a stand alone "special" gdb bundled with mpich2...

Thanks for your help
Burlen
