Toruqe PBS常见问题汇总

$ mpirun -np 25 python -c "print 'hey'"
--------------------------------------------------------------------------
There are not enough slots available in the system to satisfy the 25 slots 
that were requested by the application:
  python
Either request fewer slots for your application, or make more slots available
for use.

问题原因，如果使用了PBS提交任务，那么不应该直接指定np参数，应该使用PBS的变量来计算得到np参数的值

mpirun was unable to launch the specified application as it could not access
or execute an executable:
Executable: /orca_gtoint_mpi
Node: node01
while attempting to start process rank 0.

问题原因，exe变量有问题，就是说找不到可执行文件，检查mpirun后面的参数

[root@node272 ~]# qstat -q
socket_connect_unix failed: 15137
socket_connect_unix failed: 15137
socket_connect_unix failed: 15137
qstat: cannot connect to server (null) (errno=15137) could not connect to trqauthd
qstat: Error (15137 - could not connect to trqauthd)

问题原因：trqauthd服务没有启动，或者是该节点没有加入到Torque队列系统当中

解决办法：启动trqauthd服务，或者将节点加入到Torque队列系统中。
