I've built the latest 1.5.4 release for one of our SLURM clusters now Totalview only appears to debug the main job launcher that calls orterun(). The actual MPI job still runs on the specified number of nodes yet TV doesn't seem to see it.
Here's my launch line:
$ totalview mpirun -a -n 16 my.exe
The same application built against ompi-1.4.3 debugs just fine under Totalview.
