- Mixing compilers from different vendors when building Open MPI

(e.g., using the C/C++ compiler from one vendor and the F77/F90

compiler from a different vendor) has been successfully employed by

some Open MPI users (discussed on the Open MPI user's mailing list),

but such configurations are not tested and not documented. For

example, such configurations may require additional compiler /

linker flags to make Open MPI build properly.

- Open MPI does not support the Sparc v8 CPU target, which is the

default on Sun Solaris. The v8plus (32 bit) or v9 (64 bit)

targets must be used to build Open MPI on Solaris. This can be

ptmalloc2 support in v1.3.2 such that the
