我在使用 Torque + Maui 时遇到了麻烦。
问题如下：我有 2 个队列，每个队列有 10 个关联节点。如果我向第一个队列提交 10k 个作业，向第二个队列提交 1 个作业，则第二个队列中的作业仍处于 Q 状态。
[root@localhost bin]# ./showstart 366808
job 366808 requires 2 procs for 1:00:50
Earliest start in 00:00:00 on Fri Dec 18 16:27:21
Earliest completion in 1:00:50 on Fri Dec 18 17:28:11
Best Partition: DEFAULT
[root@localhost bin]# ./checkjob -v 366808
.....
PE: 2.00 StartPriority: 3
job can run in partition DEFAULT (80 procs available. 2 procs required)
[root@localhost bin]# ./diagnose -n
Total Nodes: 20 (Active: 10 Idle: 10 Down: 0)
[root@localhost server_logs]# cat 20151218 | grep 366808

12/18 16:25:06 MJobPReserve(366808,DEFAULT,ResCount,ResCountRej)
我们可以看到，这不是资源问题，因为 Maui 明确表示该作业可以执行。
仅当我使用 qrun 强制执行时，该作业才会执行
