Fatal error in MPI_Init: Other MPI error, error stack: MPIR_Init_thread(264): Initialization failed


I am running Intel MPI for Intel mp_linpack benchmark (xhpl_em64t).


1. I sourced the from /opt/intel/impi/bin64/

2. I did "mpdboot -f hostfile"

$ cat hostfile
node 1
node 2

3. I did "mpirun -f hostfile -ppn 1 -np 2 ./xhpl_em64t"

After step 3, errors occured. Below is the error message with I_MPI_DEBUG=50

DAPL works but OFA not

Dear Intel colleagues,

I have just set up a new diskless cluster. Running IMB "Pingpong" with -genv I_MPI_FABRICS shm:dapl shows promising performance. But with -genv I_MPI_FABRICS shm:ofa things never worked. I have provided all system environment and execution traces below. Your help will be important to us.
