!!! The CPU_NUM is not specified, you should set CPU_NUM in the environment variable list.
CPU_NUM indicates that how many CPUPlace are used in the current task.
And if this parameter are set as N (equal to the number of physical CPU core) the program may be faster.

export CPU_NUM=8 # for example, set CPU_NUM as number of physical CPU core which is 8.

!!! The default number of CPU_NUM=1.
