Module burncpu is a worker dispatcher with multiprocessing and multithreading.
Features
All CPU cores can be used.
Workers can be stopped gracefully by system signals.
Pure python code.
Quickstart
Use the following command to run the sample module.
python3 -m burncpu.sampleThen monitor CPU status, some changes take place at these time.
Time |
Events |
|---|---|
0s |
All CPU cores are IDLE. |
10s |
Workers begin to call one_second_task many times. |
60s |
Workers begin to terminate. |
Pressing Ctrl+C or sending system signal can also terminate the sample.
Finally copy and modify the source code to make your own.
Reference
To import
from burncpu.dispatcher import WorkerDispatcherclass WorkerDispatcher
WorkerDispatcher.__init__(worker_count=0, use_core=0, time_limit=0)
Create a dispatcher instace.
- worker_count
How many threads would be created, 0 means to create (use_core * 2) threads.
- use_core
How many cores would be use, 0 means all cores.
- time_limit
Stop workers after given seconds. Running functions still run at that moment. Queued functions would be cancled.
WorkerDispatcher.dispatch(func, args)
Dispatch a function to one of workers randomly.
- func
Function to call.
- args
Argument list of this function.
WorkerDispatcher.sleep(seconds)
Sleep dispatcher for given seconds.
- seconds
Seconds to sleep. Dispatcher would not sleep given seconds actually. It sleep many times during given seconds, so that system signal (e.g. Ctrl+C) can be handled.
WorkerDispatcher.join()
Wait until all workers stopped.
WorkerDispatcher.is_alive()
Check if the dispatcher is alive.
