This presentation is a "lessons learned" summary of some 20 years of experience designing, developing, and maintaining a large-scale commercial software system for the users who are primarily interested in performance. Competitive benchmarks are the dominant factor in our users' decisions whose tool to buy.

A high-quality implementation, a skillful optimization, can win the day in such environment. But only the day. The design determines the long-term survival. Parts of the system have grown ten-fold in size and complexity, but still fundamentally use the original architecture and show no sign of strain. Others had to be radically redesigned or even rewritten from scratch. The designs of the former type tend to share certain characteristic properties, which we came to recognize. These are design patterns of high-performance software, at least in our experience. The design of the latter type, unfortunately, exhibit an infinite variety of poor decisions, although some mistakes (anti-patterns?) are repeated over and over.

In this presentation, I will show the most important patterns and practices of design for performance that I have learned. Some will be obvious, especially after you hear them. Others may be controversial (for example, sometimes you should optimize prematurely if you want to be able to optimize at all). I may even present some of the anti-patterns, but only for laughs and to make the listeners feel better about their own design mistakes.

Fedor Pikus, Siemens
Chief Scientist

Fedor G Pikus is a Chief Engineering Scientist in the Design to Silicon division of Mentor
Graphics Corp (Siemens business). His earlier positions included a Senior Software Engineer at Google and a Chief Software Architect for Calibre PERC, LVS, DFM at Mentor Graphics. He joined Mentor Graphics in 1998 when he made a switch from academic research in computational physics to the software industry. Fedor is a recognized expert on high-performance computing and C++, he presented his works at CPPCon, SD West, DesignCon, in Software Development Journal, and is also an O’Reilly author. His responsibilities as a Chief Scientist include planning the long-term technical direction of Calibre products, directing and training the engineers who work on these products, design, and architecture of the software, and research in the new design and software technologies. Fedor has over 25 patents and over 100 papers and conference presentations on physics, EDA, software design, and C++ language.
