Java Thread Affinity: Binding Threads to Specific CPU Cores

The question arises from a user's desire to restrict individual threads within a Java process to specific CPU cores on Linux. This is achievable in C, but the user seeks guidance on how to replicate this functionality in Java.

JNI Approach

The solution lies in utilizing JNI (Java Native Interface) to invoke native code capable of executing this task. While pure Java code lacks this functionality, JNI provides a bridge between Java and native environments.

Relevant Resources

• [CPUThread Affinity in Java](http://blog.toadhead.net/index.php/2011/01/22/cputhread-affinity-in-java/)

ThreadAffinity.java

Additionally, a custom Java class called ThreadAffinity.java has been developed to facilitate thread affinity management. Based on JNA (Java Native Access), it offers a straightforward interface for setting thread affinity in Java.

Alternative Library

An alternative thread affinity library for Java is also available, employing a similar mechanism with a distinct interface.
