[ version history ] verions 3.x - moved to version 1.6.3 - added affinitylock.isallocated() and isbound() so you can check whether a cpu could be allocated. version 1.6.2 - initial implementation for mac os for its thread policies. this is not the same as affinity but may be equivalent. version 1.6.1 - improved behaviour on machines without thread affinity support esp. macs. version 1.6 - first formal release available under version 1.5.5 - added native support for linux/amd64, thank you akerbos. version 1.5.4 - added native support extracted from jar and native build for linux/i386, thank you isopov. version 1.5.3 - build on windows cleanly. added

When busy-spining Java thread is bound to physical core, can context switch happen by the reason that new branch in code is reached?

QUESTION

When busy-spining Java thread is bound to physical core, can context switch happen by the reason that new branch in code is reached?

Asked 2020-Nov-01 at 21:20

I am interested in low-latency code and that`s why I tried to configure thread affinity. In particular, it was supposed to help to avoid context switches.

I have configured thread affinity using https://github.com/OpenHFT/Java-Thread-Affinity. I run very simple test code that just spins in a cycle checking a time condition.

A voluntary context switch usually means a thread is waiting for something, e.g. for a lock to become free.

async-profiler can help to find where context switches happen. Here is a command line I used:
