Hi
I am trying to run NAS with I-MPI version 3.2.1.
The following is the command:
mpiexec -rr -n 256 -env I_MPI_FALLBACK_DEVICE 0 -env I_MPI_DYNAMIC_CONNECTION disable
-env I_MPI_USE_RENDEZVOUS_RDMA_WRITE 1 -env I_MPI_DEVICE rdssm:ofa-v2-ib0 /home/NPB3.3/NPB3.3-MPI/bin/bt.A.256
I am getting error:
[0] ERROR - MPI startup(): dlopen() of dat library failed
[1] ERROR - MPI startup(): dlopen() of dat library failed
...
..
[255] ERROR - MPI startup(): dlopen() of dat library failed
[1] DAPL provider is not found and fallback device is not enabled
[0] DAPL provider is not found and fallback device is not enabled
[cli_0]: aborting job:
Fatal error in MPI_Init: Other MPI error, error stack:
MPIR_Init_thread(283): Initialization failed
MPIDD_Init(98).......: channel initialization failed
MPIDI_CH3_Init(163)..: generic failure with errno = -1
(unknown)():
--------------------------------------------------------------------------------------
But I am able to run IMB over the same setup, with the same command:
mpiexec -rr -n 256 -env I_MPI_FALLBACK_DEVICE 0 -env I_MPI_DYNAMIC_CONNECTION disable -env I_MPI_USE_RENDEZVOUS_RDMA_WRITE 1 -env I_MPI_DEVICE rdssm:ofa-v2-ib0 /home/bin_imb/intel/IMB-MPI1_impi_gcc
How to resolve the problem with NAS benchmark?

Hi Grovershah,
Could you tell me how you compiled /home/NPB3.3/NPB3.3-MPI/bin/bt.A.256?
and what is the difference with /home/bin_imb/intel/IMB-MPI1_impi_gcc?
It seems to me that you used different environment to built these 2 applications.
Regards!
Dmitry
