To use TotalView with IBM PE MPI codes:

1. You must prepare your parallel application to use the TotalView HIA; see LIBPATH and Linking and Installing tvheap_mr.a on AIX. Here is an example that usually works:

mpcc_r -g test.o -o test -Lpath_mr -Lpath \

path/aix_malloctype.o

2. Start TotalView on poe as usual:

totalview poe -a test args

Because tvheap_mr.a is not in poe’s LIBPATH, enabling TotalView upon the poe process will cause problems because poe will not be able to locate the tvheap_mr.a malloc replacement library.

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

4. Run the poe process.
