Minor documentation nit, which might apply to the 1.5 branch as well
(didn't check).
README says:
- 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
done by including a flag in CFLAGS, CXXFLAGS, FFLAGS, and FCFLAGS,
-xarch=v8plus for the Sun compilers, -mcpu=v9 for GCC.
However, following that instruction w/ Sun Studio 12 Update 2 yields:
cc: Warning: -xarch=v8plus is deprecated, use -m32 -xarch=sparc instead
for every single compilation.
I vaguely recall noting this once before, perhaps 2 years or so.
Additionally, it appears that the "Sun" example is for the 32-bit ABI
and the "GCC" example for the 64-bit ABI.
This is potentially a bit confusing.
