Hi,
we (my collegue Andreas and me) are still trying to solve this
problem.
I have compiled some additional information, maybe somebody has an
idea
about what's going on.
OS: Debian GNU/Linux 4.0, Kernel 2.6.18, x86, 32-Bit
IB software: OFED 1.1
SM: OpenSM from OFED 1.1
uDAPL: DAPL reference implementation version gamma 3.02 (using DAPL
from
OFED 1.1 doesn't change anything, I suppose it's the same code, at
least
roughly)
Test program: Intel MPI Benchmarks Version 2.3
OpenMPI version: 1.2.1
Running OpenMPI directly over IB verbs (mpirun --mca btl
self,sm,openib
...) works. Here's the output of ibv_devinfo and ifconfig for the two
nodes on which tried to run the benchmark (ulimit -l is unlimited on
both machines):

The jobs hangs at this point. From the output of another simple test
program I assume that it hangs inside of a receive operation. Of
course,
I have noticed the "Permission denied" messages, but I don't think
that
the probleme is there. These messages seem to come from RDMA CM when
things are set up, but the execution continues from there on and I
have
seen these messages on successful DAPL runs, too. I'm not very
familiar
with RDMA CM, though, so I don't know the cause of these messages.
That's a lot of information, I know, but it would be great if someone
would have a look at it.
Thanks in advance

On Linux you needn't initialise the dat registry. Your program
prints:
"provider 1: OpenIB-cma". I successfully tested INTEL MPI and
mvapich2
with uDAPL .

Andreas,
I am going to guess at a minimum the interfaces are up and you can
ping them. On Solaris there is an additional step required and
that
is initializing the dat registry. If "/usr/sbin/datadm -v" does not
show some driver output then you would need to run "/usr/sbin/
datadm
-a /usr/share/dat/SUNWudaplt.conf". I don't know if there is an
equivalent on Linux.
Attached is a simple udapl program which will check if the
interfaces
are available in the dat registry.
