Oversubscribing number of threads in each thread group. If this parameter is set to the default value, this parameter indicates the oversubscribing number of threads of each CPU core. The default value is 3, which is an empirical value that can fully utilize CPU resources. If this parameter is set to a value smaller than 3, more sleep and wakeup events may occur. If the number of active working threads in a thread group exceeds the value of this parameter, the system considers that there are too many active working threads and you need to reduce this number.
