A wrapper over net.openhft:affinity providing handy classes to create threads pinned to the specified cpus.
Use the following sample to log a message:
int[] cpus = {0, 1};
AffinityLayout affinity = new FixedAffinityLayout(cpus);
PinnedThreadFactory factory = new PinnedThreadFactory("my-thread", affinity);
Runnable runnable = () -> {
System.out.println("Hello world!");
System.out.println("Thread: " + Thread.currentThread());
System.out.println("Affinity: " + Affinity.getAffinity());
};
Thread thread = factory.newThread(runnable);
thread.start();Build the project with Gradle and Java 8:
./gradlew build
