Faster Programs with Your Compiler's Autovectorization Feature

Learn how to leverage your compiler's autovectorization capabilities to significantly improve C++ program performance in this 42-minute conference talk from NDC TechTown. Explore the fundamentals of vector instructions and understand the autovectorization process where compilers automatically generate vector instructions to accelerate loop execution. Focus on identifying and resolving vectorization inhibitors - specific code patterns that prevent automatic compiler vectorization. Examine real examples of unvectorized loops, analyze CLANG's vectorization reports, and discover practical solutions that can make your code several times faster with minimal modifications to your existing C++ codebase.
