Intel Compilers for C/C++ and Fortran empower developers to derive the greatest performance from applications and hardware. In this video, Igor Vorobtsov discusses nuances of Intel compiler features which enable high-level optimization, auto-parallelization, auto-vectorization, dynamic profile guided optimization, detailed optimization reports, inter-procedural optimization (IPO), and much more.
Intel Compilers 18.0 Tune for AVX-512 ISA Extensions
Intel Compilers 18.0 and Intel Parallel Studio XE 2018 tuning software fully support the AVX-512 instructions. By widening and deepening the vector registers, the new instructions and added enhancements let the compiler squeeze more vector parallelism out of applications than before. Applications compiled with the –xCORE-AVX512 will generate an executable that utilizes these new high-performance instructions.
Intel Parallel Studio XE 2018 Released
Intel has announced the release of Intel® Parallel Studio XE 2018, with updated compilers and developer tools. It is now available for downloading on a 30-day trial basis. ” This week’s formal release of the fully supported product is notable with new features that further enhance the toolset for accelerating HPC applications.”
Let The Compiler Do Its Thing
“In the past, developers would get best results if a loop was unrolled, that is, duplicating the body as many times as needed to that the operations could be operated on using full vectors. The number of iterations would reflect the hardware that the code was targeted towards. Since the application may have to run on different hardware in the future, results for todays generation of hardware may be compromised in the future. In fact, it is better to let modern compilers to the unrolling.”
