SGI MPI

There are two ways to use MemoryScape on SGI MPI code. In most cases, all you need do is select the Debug > Enable Memory Debugging command upon the mpirun process. Once in a while, this may cause a problem. If it does, here’s what you should do:

1	Link your parallel application with MemoryScape’s agent as described in the “Linking Your Application With the Agent”. Roughly:

cc -n32 -g test.o -Lpath -ltvheap -rpath path \

-lmpi -o test

2	Start TotalView on mpirun. For example:

totalview mpirun -a mpirun-args test args

3	If you need to modify the memory debugging options, you should do it now in MemoryScape.

4	Run the mpirun process.

5	Select Debug > Open MemoryScape from the menu to open MemoryScape to examine your memory usage.
