In trying to build 1.2.6 with the pgi compilers it makes an MPI

Both our intel compiler version and pgi version of 1.2.6 blow up
like this when we force IB. So this is a new issue.
I have ompi 1.2.6 installed on my machines with Intel compiler
(version 10.1) and Pgi compiler (version 7.1-5), both of them works
with IB without any problem. BTW Mellanox provides Mellanox OFED
binary distribution that include Intel and Pgi Open MPI 1.2.6 build.
You can download it from here http://www.mellanox.com/products/

Is there a way to shut off early completion in 1.2.3?
Sure, just add "--mca |pml_ob1_use_early_completion 0" to your
command line.| ||
Note that this flag was not added until v1.2.6; it has no effect in
v1.2.3.
Or the the above a known issues and i should use 1.2.7-pre or grab
a 1.3 snap shot?
1.2.6 should be ok.
The upcoming v1.3 series works a little differently; there's no need
to use this flag in the v1.3 series (i.e., this flag only exists in
the v1.2 series starting with v1.2.6).
