[求助] VASP提交的作业没算完,出现错误

一开启计算终端SecureCRT,提交VASP作业出现错误信息是mpiexec_a2: cannot connect to local mpd (/tmp/mpd2.console_whh); possible causes:
  1. no mpd is running on this host
  2. an mpd is running but was started without a "console" (-n option)
In case 1, you can start an mpd on this host with:
    mpd &
and you will be able to run jobs just on this host.
For more details on starting mpds on a set of hosts, see
the MPICH2 Installation Guide.我就启动mpd以后(mpd&),输入nohup mpirun -n 4 /home/whh/vasp/vasp.5.2/vasp > out&进行计算,如果关闭SecureCRT终端,就出现作业死了,能看到的错误信息就是mpiexec_a2 (handle_stdin_input 1090):     e.g.: mpiexec -n 4 a.out < /dev/null &
mpiexec_a2 (handle_stdin_input 1089): stdin problem; if pgm is run in background, redirect from /dev/null
mpiexec_a2 (handle_stdin_input 1090):     e.g.: mpiexec -n 4 a.out < /dev/null &
mpiexec_a2 (handle_stdin_input 1089): stdin problem; if pgm is run in background, redirect from /dev/null,今天不关闭SecureCRT终端,计算作业也没有算完就出现mpiexec_a2 (handle_stdin_input 1090):     e.g.: mpiexec -n 4 a.out < /dev/null &
mpiexec_a2 (handle_stdin_input 1089): stdin problem; if pgm is run in background, redirect from /dev/null
mpiexec_a2 (handle_stdin_input 1090):     e.g.: mpiexec -n 4 a.out < /dev/null &
mpiexec_a2 (handle_stdin_input 1089): stdin problem; if pgm is run in background, redirect from /dev/null,作业没算完就死了。现在计算原胞也还是可以正常结束的!麻烦有经验的兄弟姐妹帮我看看是怎么回事,谢谢了!
