My apologies, Manal I had a slight error on the command line I gave you. It should be:
mpirun np XX xterm e gdb <myprog> When the xterm windows pop-up, you will need to enter each of them and type run <myargs> To start the program. If you want gdb to use a specific directory, you can pass the ³-d <mydir>² argument in the first command line: mpirun np XX xterm e gdb d >mydir> <myprog> You would still need to issue the ³run² command in each xterm window. Sorry for the error. Ralph On 11/10/06 7:48 PM, "Ralph Castain" <r...@lanl.gov> wrote: > Hi Manal > > No problem at all happy to be of some help.
