MPICH

Here's how to use MemoryScape with MPICH MPI codes. Rogue Wave Software has tested this only on Linux x86.

1	You must link your parallel application with the MemoryScape agent as described “LIBPATH and Linking”. On most Linux x86 systems, you’ll type:

mpicc -g test.o -o test -Lpath \

-ltvheap -Wl,-rpath,path

2	Start MemoryScape using the –tv command-line option to the mpirun script in the usual way. For example:

mpirun -tv mpirun-args test args

MemoryScape will start up on the rank 0 process.

3	If you need to configure MemoryScape, you should do it now.

4	Run the rank 0 process.
