"Thus, systems builders and datacenter developers must start thinking of the world beyond software and start looking to hardware for solutions. They cannot continue focusing on software running on general-purpose...

This is the current available_permits. I need the max capacity. Example with this feature: ```rust #[tokio::main] async fn main() { // ... let (tx, mut rx) = tokio::sync::mpsc::channel(100); some_func_with_monitoring(tx.clone()).await; //...

My purpose is to monitor and periodically report the buffer usage rate which equals `tx.capacity()/tx.max_capacity()` in a separate tokio coroutine.

Thanks for your reply! I got the following output, and I guess it means: my application used two CPUs (CPU 0 and CPU 10); during the running, CPU 0 consumed...

Thanks for your answer! Now I know the meaning exactly. Another question is now I want to do scheduling based on the output information. My scheduler is supposed to be...

My scheduling is to change knobs like power limit based on the energy consumption in this computer (2 CPU + 1 GPU). Thanks for your kind help again!

I will take a look and use them. Thanks for your careful and informative explanation!
