Kurt,
the error is "valgrind myApp" is not an executable (but this is a
command a shell can interpret)
so you have several options:
- use a wrapper (e.g. myApp.valgrind) that forks&exec valgrind myApp)
- MPI_Comm_spawn("valgrind", argv, ...) after you inserted "myApp" at
the beginning of argv
-
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
