The course concentrates mostly on application performance improvements with Intel Compiler and VTune Amplifier.
It briefly describes microprocessor architecture; application performance factors and common speedup techniques:
scalar optimizations, loop optimizations, vectorization, parallelization, interprocedural optimizations and profiler guide optimizations. The course describes compiler architecture and command line options, compiler limitations and methods of providing additional information to the compiler. It gives a first insight to the performance analysis. Practical examples help to become familiar with VTune usage and the ideas of performance optimization.

Лекция 154 минуты | Introduction to application optimizations with usage of Intel® performance tools
At the first lecture common Intel microprocessor architecture and the main factors affecting its performance are described. The simplified microprocessor model is used to show the subsystems role and describe the main features such as multi-level memory model, common and vector registers, data prefetching mechanism, branch prediction, pipeline and superscalar features, vector instructions, multi-core, multi-processor. Performance optimization compiler role is also described.
