MPICH
Here's how to use MemoryScape when launching MPICH MPI codes from the command line.
1 You must link your parallel application with MemoryScape’s agent as described in “Linking Your Application With the Agent”. On most Linux x86 systems, you’ll type:
mpicc -g test.o -o test -Lpath -ltvheap -Wl,-rpath,path
2 Start TotalView using the -tv command-line option to the mpirun script in the usual way. For example:
mpirun -tv mpirun-args test args
TotalView will start up on the rank 0 process.
3 Because you will have linked in MemoryScape’s agent, memory debugging is automatically selected in your rank 0 process.
4 If you need to modify the memory debugging options, you should do it now in MemoryScape.
5 Run the rank 0 process.
6 Select Debug > Open MemoryScape from the menu to open MemoryScape to examine your memory usage.
