Hi, I need help!!

We built a cluster today, with 1 MIC card in every node, and the server is E5-2670 V3 CPU, and we installed nfs, nis, rsh, ssh, mpss service, and we installed intel parallel studio 2015 update2. However, when I run xhpl_offload_intel64  which is from mkl/benchmarks/mp_linpack/bin_intel/intel64/benchmarks/mp_linpack/bin_intel/intel64/, there is no problem when running in one node, however, when I want to run linpack in 2 nodes by the command: mpirun --perhost 1 -n 2 -hosts ibmic01,ibmic03 -genv MIC_LD_LIBRARY_PATH $MIC_LD_LIBRARY_PATH -genv LD_LIBRARY_PATH $LD_LIBRARY_PATH ./xhpl_offload_intel64, there is an error: segmentation fault. and there is no process in any nodes. What's more, when I run the parallel application like WRF, PALABOS.

What's wrong with our cluster? Is there any problem with my environment? or our compiler has some problem?

Please help me within 24 hours. Thank you!!!!!!
