Affinity in Java thread

Question

How do we lock down the individual threads contained within the Java processes that are specific to the CPU core. Any suggestion will be helpful.

Answer 1

Well, as far as I know, I don't think Java allows that.

But you can use an underhand method where you need to make use of JNI in order to invoke the native codes that will execute the program. For more detail, you can refer here:
