ABSTRACT:  Mechanical Sympathy

“Mechanical Sympathy” is a phrase (as well as a blog) applied by Martin Thompson to how to write software that cooperates with the underlying CPU architecture.  We will discuss how to use “mechanical sympathy” to get high-performance multi-threading behavior in Java up to 100s of times greater than using traditional locking or by using the concurrency classes by using “lock-free” techniques that take into account how “memory barriers” effect performance.
