So you specify --with-ofed and you get mca_btl_openib generated? ICK!!! I
think that will just make things more confusing. I am against this unless you
change the btl name.

It looks like compilation of 32 bit platforms is failing due to a

With Jeff's latest changes to how we set up the cq_size I am now seeing
error messages saying that my machine's memlocked limits are too low. I
am concerned that it might be something else because my max'd locked

Interestingly enough it worked for me for a while and then after many

IIRC, the first 16 or so messages over the openib btl uses the send/recv

to how 1.5.3 and multi-rail affects this but the preconnected I believe
short circuits when one cuts over to use rdma for eager messages.

however I wonder does it actually makes sense to print out an MPI
