September Concurrent Lock Free Programming in Java
By the end of this course candidates will have acquired an in-depth knowledge of concurrent programming that allows them to develop data structures such as queues, executors, and shared memory IPC transports that significantly out perform any products currently available.
In addition to learning the basic techniques of building high-performance data structures, a performance testing and profiling methodology will be introduced that is fundamental to working at the extremes of systems performance.

Additional Information
The course is a blend of lectures, coding exercises, and workshops. Solutions will be provided to the exercises that are of sufficient quality for deployment to production systems. Candidates should bring along a laptop capable of running at least 4 threads concurrently, i.e. dual core with Hyperthreading enabled. Though not a requirement, systems with Linux installed can participate in deeper profiling exercises.
