Hello Sir,
In the implementation of MPI there are so many collective call
implementations. I just want to when is the tuned collective calls called.
What is it that I need to so that always tuned collective calls are called?
Thank You

The MPICH folks, who lurk on this list (gasp!), actually replied to me offlist
and pointed out that they had pretty much the same problem, and pointed out a
clever solution. Thanks, MPICH guys!
I committed a fix to the trunk and to v1.6 (and will CMR it to v1.7, too).
This is, admittedly a f
You should definitely be able to disable fortran on the trunk. The option

Yup, gfortran was the problem. It works now.
It also explains why the trunk version worked. In the trunk you can't
disable fortran at all, so I had to uninstall gfortran.
Thanks for all the help.

I looked closer at your configure output this morning, and I think I see the

configure:163699: gfortran -c -o out/conftest2.o conftest.f >&5

I think it's a typo, I should have written 'qrsh'
All machines are the same regarding speed and core count?
yes
