Subject: [OMPI devel] 1.6.2rc2 build failure w/ icc on IA64
From: Paul Hargrove (phhargrove_at_[hidden])

I have reported as long ago as 1.4.5rc2 (see
http://www.open-mpi.org/community/lists/devel/2012/01/10256.php ) that Open
MPI does not build with the Intel compilers (versions 9.1 and 10.0 tested)
on IA64.

This is still true with 1.6.2rc2, and I doubt anybody plans to fix this
soon, if ever.
HOWEVER, the following still appears in OMPI's README and suggests to the
casual reader that ICC 9.1 and 1.0 on IA64 should probably work:

> - The Intel 9.0 v20051201 compiler on IA64 platforms seems to have a

There is no other mention of IA64 in the README and the other Intel
compiler issues are not related.

So, I think the README could use an update with respect to IA64 and ICC.
Note that I can build w/ gcc just fine on IA64, but I'd not exactly break
down in tears if OMPI dropped support for IA64 entirely.
