Hi Jeff,
> Should these 2 components be in v1.3?
for LibNBC: no. This was a test to implement blocking colls on top of
non-blocking when the tuned implementation was lacking some ops (e.g.,
Allgather). Tuned now efficiently implements most collectives which
makes the blocking version of LibNBC unne

thanks for your comment and this will not go to /dev/null!

Hi folks,
WHAT:
Merge the htor-nbc branch to the trunk. This branch adds LibNBC support
to Open MPI (via compiler-wrappers mpi{cc,CC,xx,f90,..

Hi Galen,Gleb,
there is also something weird going on if I call the basic alltoall
during the module_init() of a collective module (I need to wire up my
own QPs in my coll component). It takes 7 seconds for 4 nodes and more
than 30 minutes for 120 nodes. It seems to be an OpenIB wireup issue
becaus

I would say that S=(N-1)*P (why do you assume that S=O(P^2)?) i

Hi all,
after having some off-list conversation about enabling thread support
for applications using Open MPI, I found several errors during
compilation (revision 6701 with --enable-mpi-threads):
* mutex.h:267
OMPI_SIZEOF_SIZE_T is not defined
* orte_pointer_array.c:358
table is not defined

yes, it's ok for me - I'll ask the vcc and reply to this mail if they
have any problems.
