Hello Galen, Finally I've got some time to look through the new code. I have couple of notes. In pml_ob1_rdma.c you try to merge registrations in the number of places. The code looks like this: btl_mpool->mpool_deregister(btl_mpool, reg); btl_mpool->mpool_register(btl_mpool,

Thats correct. Not sure why TCP would have been used - unless IB interfaces weren't up.. Brian Barrett wrote: Tim - Just to make sure I"m not losing it - if any of the "high speed" networks is found between peers, tcp shouldn't be used between that pair, right? I was pretty sure that's wh

[O-MPI devel] mpif.h problems

2005-09-21 Thread David R. (Chip) Kent IV
I managed to find a number of problems with the mpif.h when I tried it on a big application. It looks like a lot of key constants are not defined in this file. So far, MPI_SEEK_SET, MPI_MODE_CREATE, MPI_MODE_WRONLY have broken the build. I've added them to mpif.h as I find them so that I can
