A worker dispatcher with multiprocessing and multithreading.
Module burncpu is a worker dispatcher with multiprocessing and multithreading.
- All CPU cores can be used.
- Workers can be stopped gracefully by system signals.
- Pure python code.
Use the following command to run the sample module.
python3 -m burncpu.sample
Then monitor CPU status, some changes take place at these time.
|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.
from burncpu.dispatcher import WorkerDispatcher
WorkerDispatcher.__init__(worker_count=0, use_core=0, time_limit=0)
Create a dispatcher instace.
- How many threads would be created, 0 means to create (use_core * 2) threads.
- How many cores would be use, 0 means all cores.
- Stop workers after given seconds. Running functions still run at that moment. Queued functions would be cancled.
Dispatch a function to one of workers randomly.
- Function to call.
- Argument list of this function.
Sleep dispatcher for given 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.
Wait until all workers stopped.
Check if the dispatcher is alive.
