This class is offered as CS6290 at Georgia Tech where it is a part of the [Online Masters Degree (OMS)](http://www.omscs.gatech.edu/). Taking this course here will not earn credit towards the OMS degree. The course begins with a lesson on performance measurement, which leads to a discussion on the necessity of performance improvement. Pipelining, the first level of performance refinement, is reviewed. The weaknesses of pipelining will be exposed and explored, and various solutions to these issues will be studied. The student will learn hardware, software, and compiler based solutions to these issues.

- Milos Prvulovic - Dr Prvulovic's research focuses on architectural (hardware) support for program monitoring, debugging, and security, particularly in multi-threaded and multi-core systems. In general, the goal of his research is to make both hardware and software more reliable and secure. He is the area coordinator for the Computer Architecture area in the School of Computer Science at Georgia Tech. Dr. Prvulovic received his Ph.D. from the University of Illinois at Urbana-Champaign in 2003. He is a Senior Member of ACM and IEEE and is currently serving as the Secretary-Treasurer of ACM SIGMICRO.
Udacity is a for-profit educational organization founded by Sebastian Thrun, David Stavens, and Mike Sokolsky offering massive open online courses (MOOCs). According to Thrun, the origin of the name Udacity comes from the company's desire to be "audacious for you, the student". While it originally focused on offering university-style courses, it now focuses more on vocational courses for professionals.
