[mpich-discuss] Build x86 version mpich2 on x86_64 Linux Boxfailed ...

[Jayesh Krishna]

Hi Seifer,

>>> I don't know if nemesis may conflict with smpd...

	There are some known issues
(https://trac.mcs.anl.gov/projects/mpich2/ticket/292) with multithreaded
MPI programs when you use smpd with nemesis (The bug/hang is not specific
to nemesis but shows up easily with nemesis). We will be fixing this bug
in the upcoming 1.1rc1 release. If you don't plan to use multithreaded MPI
programs, SMPD should work just fine with nemesis.

Regards,
Jayesh

Then think about sticking to mpich2-1.0.8p1, which is the right and wise
thing to do, and of rebuilding your programs with it.

I would suggest building with the ch3:nemesis communication channel,
instead of ch3:sock, which seems to be the default.
Some people reported problems with ch3:sock on current Linux kernels and
some types of Ethernet cards on this list and elsewhere.

However, I am not sure about nemesis in your case just because you seem to
prefer the smpd (--with-pm=smpd --with-pmi-=smpd).
I don't know if nemesis may conflict with smpd.
I never used smpd.
The MPICH2 developers may clarify this point.

If you rebuild with nemesis, follow Rajeev's suggestion also:
delete the directory tree, untar again, and start fresh, to avoid old
object files on your way.

I hope this helps.
