HTCondor基于空闲改变NUM\u cpu?

我想根据是否有人在机器上工作来更改CPU计数。不想抢占手册中定义的作业。做一些类似的事情:

// condor_config file
if (KeyboardIdle < 10)
    NUM_CPUS = 2
else
    NUM_CPUS = 8
endif

(KeyboardIdle < 10) is not a valid if condition because complex conditionals are not supported .

不管我用什么方法来实现这一点 NUM_CPUS

根据格雷格的回答,我的秃鹰配置的最底部如下

NUM_CPUS = 16
START = (SlotID < 8) || (KeyboardIdle > 10)

理论上只允许启动8个作业,但不允许运行 condor_status myMachine 我得到:

有什么想法吗?

HTCondor中的NUM\u cpu是固定的。通常,实现这种策略的方法是更改START表达式,这样就有不同数量的槽,其START表达式的计算结果为false,因此无法启动作业。

假设这台机器有静态插槽(默认),开始表达式可以是

START = (SlotID < 3) || (KeyboardIdle > 10)

PREEMPT = (SlotID > 3) && (KeyboardIdle < 10)
