换句话说,并行度值为 5 和优先级值为 1000 意味着什么?

最佳答案

它们会影响您的作业运行方式和时间。优先级决定了一个作业相对于其他排队作业的运行顺序,并行度设置了为其启动多少个并行进程(更多意味着它运行得更快,但成本更高)

优先级

Lower number has higher priority. If two jobs are both queued, the one with lower priority runs first

默认值为 1000。

并行性

Max number of compute processes that can happen at the same time. Increasing this number can improve performance but can also increase cost.
