“Unlock next-gen hardware performance secrets for your HPC codes; enable SIMD AVX/AVX-512 vector parallelism with Intel code modernization tool »


Software must be optimized for SIMD vector parallelism to achieve scaled performance on modern hardware. The gap between unoptimized baseline and SIMD+thread parallel code performance is increasing every year. SIMD code modernization is not without cost, but new capabilities of OpenMP 4.x “explicit vectorization” and new Intel® “Vectorization Advisor” software tool make it possible to introduce efficient and portable SIMD parallelism without disrupting ongoing development. Even with perfect vectorization developers often have to additionally balance CPU/vectors/thread utilization vs. memory sub-system data bottlenecks. This problem is also addressed with new experimental Intel Advisor 2017 capabilities (like Automated Roofline).
