rangular_mpi's issue

[zhaojingyan3]

When conducting parallel computing for big data, there is an issue of "Primary job terminated normally, but 1 process returned a non-zero exit code. Per user-direction, the job has been aborted. Mpirun noticed that process rank 2 with PID 0 on node aodexiusi exited on signal 9 (Killed)." when running the rangular_mpi program. How can I solve this problem?
