Performance Engineering Being Friendly to Your Hardware ## I GNAS BAGDONAS ## Being Friendly to Your Hardware Performance Engineering A gentle introduction to hardware for software engineers Where does C++ run vectors, specialty instructions, on-core and off-core accelerators • Data layout: both software and hardware characteristics 

enjoying the journey. - I am passionate about energy efficient computing and making the most out of older hardware, researching different platforms, tools and how to bridge different worlds and peoples together talk is an exploration of the importance of C++ as a language for writing efficient code for older hardware which is easier to access in the developing world. - It will also look into the C++ language that everyone from a “Poor” country is “Poor” and everyone from a “Rich” Country is “Rich” ## Older Hardware • As TIME has progressed, Technology has improved to make SMALLER electrical components. •

programmer's guide to efficient hardware utilization and compiler optimizations using C++ examples Fedor G. Pikus ## PLAN • Efficiency and performance • Understanding the hardware and using it efficiently efficiently – Computing resources of a CPU - Pipelining Branch prediction and hardware loop unrolling • Conditional code vs efficiency • Optimizing conditional code • Branchless programming  ## USE ALL OF THE CPU HARDWARE ALL THE TIME ## • What determines performance? • Optimal algorithm: – get the result with minimal
