qsub命令
SGE - qsub使用范例
SGE作业基本用法
qsub是最为稳定的底层任务投递系统，就是把一个脚本投递到集群的计算节点上运行。
注意，只有登录节点才有资格投递任务，计算节点没有权限投递任务，只能执行，所以千万不要在投递的脚本内嵌套投递，会报错的。
下面是我最为常用的投递命令：
qsub -cwd -l vf=5g -P 任务单元 -q 队列名
先逐条解释：
-cwd： 就是 current working directory，从当前的目录开始执行作业，也就是log文件会写到当前目录；如果不加cwd的话，就会默认输出到用户的 home 目录。如果你想指定输出目录的话，就可以使用wd命令，log会输出到你指定的目录。
-l：resource=value, 表明作业运行所需要的资源。可以看到我们后面指定了预估内存 vf=5g，一般不用指定 CPU 数。注意，实际这个没什么卵用，很少有集群能严格限制用户的内存使用，vf 只会影响你投递的效率，有人就会钻空子，尽量把内存往低了投，尽快排上。这一部分其实就是个道德约束。
-P：大型组织里会分团队，分项目，不同的项目需要制定项目名，主要是为了后期方便统计计算资源的消耗，算钱，其实这个命令没卵用。
-q：指定队列名，这个就非常重要了，队列就是计算机的队列，一个队列只有一些特定的计算节点，你投了哪个节点，你就只能用该节点指定的计算资源。
待续~
