Hi,
yesterday I installed openmpi-1.7a1r27358 and it has an improved
error message compared to openmpi-1.6.2, but doesn't show process bindings
and has some other problems as well.
"sunpc0" and "linpc0" are equipped with two dual-core processors running
Solaris 10 x86_64 and Linux x86_64 resp. "tyr" is a dual-processor machine
running Solaris 10 Sparc.

openmpi-1.6.2 shows process bindings.

On my Linux machine I get a warning.

--------------------------------------------------------------------------
WARNING: a request was made to bind a process. While the system
supports binding the process itself, at least one node does NOT
support binding memory to the process location.
Node: linpc0
This is a warning only; your job will continue, though performance may
be degraded.

Everything works fine with openmpi-1.6.2.

Om my Solaris Sparc machine I get the following errors.
