Steve,
Hey Arlin,
Have you seen this? I'm unable to get IMPI running over dapl. dtest
works with provider chelsio2, but IMPI is failing to load the libs:
[i...@r1 ~]$ mpiexec -ppn 1 -genv I_MPI_DEVICE rdma:chelsio2 -env
I_MPI_DEBUG 2 -n 2
/opt/intel/impi/3.2.1/tests/IMB-3.1/IMB-MPI1 pingpong

Hmmm, having problems finding libdat.so
What packages are installed?
# rpm -qa | grep dapl
dapl-2.0.17-1
compat-dapl-devel-1.2.14-1
dapl-utils-2.0.17-1
compat-dapl-1.2.14-1
dapl-devel-2.0.17-1
dapl-debuginfo-2.0.17-1
dapl-devel-static-2.0.14-1
can you verify libdat is in library path..
# ldconfig -p | grep libdat
libdat2.so.2 (libc6,x86-64) => /usr/lib64/libdat2.so.2
libdat2.so (libc6,x86-64) => /usr/lib64/libdat2.so
libdat.so.1 (libc6,x86-64) => /usr/lib64/libdat.so.1
libdat.so (libc6,x86-64) => /usr/lib64/libdat.so

I was building IMB 32bit and didn't have the 32b dapl installed...
I modified the mpitests Makefiles to point to the intel 64b
compiler/includes/libs and it all works now.
Thanks!
Steve.
