IntelĀ® Trace Collector 9.1 Update 2 User and Reference Guide
To automate the procedure of setting breakpoints, GNU* Symbolic Debugger (GDB) supports executing commands automatically. To apply setting this breakpoint for all programs in the current working directory, you can create a file .gdbinit with the following lines (or add them if it already exists):
set breakpoint pending on break MessageCheckingBreakpoint
Due to the order in which files are processed, placing the same commands in a .gdbinit file in the home directory does not work because the main binary is not loaded yet. As a workaround, you can put the following commands into ~/.gdbinit:
define hook-run # important, output is expected by MPI startup helper echo Starting program... # allow pending breakpoint set breakpoint pending on # set breakpoint now or as soon as function becomes available break MessageCheckingBreakpoint # restore default behavior set breakpoint pending auto end
Then start your MPI application as follows:
$ mpirun -check_mpi -gdb -n <numprocs> <app>
