Thanks Roland,
A host with CentOS 7 and a docker image "https://hub.docker.com/_/ubuntu" were used.
last month I uninstalled docker. To reproduce the errors, I reinstalled docker and use the same image today. However, unfortunately, I can not reproduce the errors. Everything works well.
I guess maybe I should run "module load mpi/openmpi-x86_64" on the host before I use docker.
I am sorry for the long delay. thanks again.
Yours, zhichao.
