How can I run OpenMPI's Memchecker on a process created by MPI_Comm_spawn()?
I've configured OpenMPI 4.0.3 for Memchecker, along with Valgrind 3.15.0 and it
works quite well on processes created directly by mpiexec.
I tried to do something analogous by pre-pending "valgrind" onto the command
passed to MPI_Comm_spawn(), but the process is not launched and it returns no
error code.
char *argv[n];
MPI_Info info;
MPI_Comm comm;
int error_code[1];
MPI_Comm_spawn ("valgrind myApp", argv, 1, info, 0, MPI_COMM_SELF,
&comm, error_code);
I didn't change the array of myApp arguments argv after adding "valgrind" to
the command; maybe it needs to be adjusted somehow.
Thanks,
Kurt
