Dear Prof. Ross
Thank you very much for your help. The openmpi I have used was installed
through yum in centos 7.3. The version info was attached below.
[jacky.DESKTOP-N0DMRU7 Amber16_Benchmark_Suite]$ rpm -qa | grep openmpi
openmpi-1.10.3-3.el7.x86_64
mpitests_openmpi_gcc_hfi-3.2-930.x86_64
openmpi-devel-1.10.3-3.el7.x86_64
openmpi_gcc_hfi-1.10.4-9.x86_64
