How to run a Python program ona specific CPU core
Question:
Say I have a python file – file1.py with arg –in
python file1.py --in 10
I have an 8-core Unix machine, I want to run the same script 8 times (infinite loop) (diff –in value) which should run in 8 different cores, like
python file1.py --in 10 –> in core 1
python file1.py --in 20 –> in core 2
python file1.py --in 130 –> in core 3
.. so on
How to implement this? How do I specify which core to run?
python file1.py --in 10 &
python file1.py --in 20 &
python file1.py --in 130 &
If I run it like this, will it run on the same core or different cores?
Answers:
Try taskset
taskset -c 1 python file1.py --in 10
taskset -c 2 python file1.py --in 20
taskset -c 3 python file1.py --in 130
