Hi<br><br><span>I am trying to get ddd to debug mpi jobs to speed things up, gdb takes a long time for me, and I need a free GUI debugger, <br><br>I debug with gdb using:<br><br>>mpirun -gdb -np </span><span>4 ./myprog</span><br>
<span><br>I found online the ddd command to be like this:<br><br>>mpirun -dbg=ddd -np 4 ./myprog<br><br>and it says:<br>invalid "local" arg: -dbg=ddd<br><br>I can not find the mpirun_dbg.ddd or mpirun_dbg.gdb after the installation and don't know if I should add them, and how and what to write in them, <br>
<br>I am having the following version information:<br>MPICH2 Version: 1.0.7<br>MPICH2 Release date: Unknown, built on Thu May 15 22:00:19 EST 2008<br>MPICH2 Device: ch3:sock<br>MPICH2 configure: -prefix=/home/mhelal/mpich2-install --enable-error-checking=all --enable-error-messages=all --enable-g=all --enable-debuginfo --enable-threads=multiple --enable-sharedlibs=gcc --with-thread-package=posix --with-namepublisher=mpd --enable-mpe<br>
