many thanks for all contributors to my past question.
Hello, I'm investigating conversion of a number of compute kernels from AVX 128 to AVX 256 and would appreciate any guidance which might be available on getting a small number of operations on port
I've started attempting to learn RTM extensions. The most common examples I can find online are using them to implement a mutex or concurrent lock. Often they are similar to:
Episode 3 of the “Hands-On Workshop (HOW) series on parallel programming and optimization with Intel® architectures” introduces data parallelism and automatic vectorization.
This code scales poorly with AVX on my Sandy Bridge, how can I make it more vectorizer friendly:
Already a couple of years ago, the Bit Manipulation Instruction Set 1 (BMI1) introduced the instruction BLSR, which resets the lowest bit that is set.
I would like to ask question about parallelization+vectorization:
I'm looking into the compilation result, of what the Intel compiler makes out of AVX512 intrinsics. (latest Intel trial compiler downloaded a few weeks ago)
