kandi X-RAY | x86doc Summary

x86doc is a Python library. x86doc has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. However x86doc build file is not available. You can download it from GitHub.

I needed a parsable copy of Intel’s x86 instruction set documentation for a personal project, so I downloaded volumes 2A and 2B of the Intel 64 and IA-32 Architectures Software Developer’s Manual (which can be found [here][1] and [here][2], respectively), and used a online PDF-to-HTML tool to transform them to HTML files. Unfortunately, the result was beyond terrible and absolutely unusable. They say that you’re never better served than by yourself, so I took the matter into my own, [pdfminer][3]-gloved hands to extract HTML pages straight from the documentation PDF themselves. This is still not perfect, but it’s already much better than the other solution (and it doesn’t involve an ugly third-party).

Using a variable to index a simd vector with _mm256_extract_epi32() intrinsic

How AVX-512CD (conflict detection) differs from atomic variables access?

QUESTION

Using a variable to index a simd vector with _mm256_extract_epi32() intrinsic

Asked 2019-Mar-13 at 20:51

I am using the AVX intrinsic _mm256_extract_epi32().

I am not entirely sure if I am using it correctly, though, because gcc doesn't like my code, whereas clang compiles it and runs it without issue.

I am extracting the lane based on the value of an integer variable, as opposed to using a constant.

When compiling the following snippet with clang3.8 (or clang4) for avx2, it generates code and uses the vpermd instruction.

Apparently GCC and Clang made a different choice. IMHO GCC has made the right choice by not implementing this for variable indices. Intrinsic _mm256_extract_epi32 doesn't translate to a single instruction. With a variable index this intrinsic might lead to inefficient code, if it is used in a performance critical loop.

For example, Clang 3.8 needs 4 instructions to implement _mm256_extract_epi32 with a variable index. GCC forces the programmer to think about more efficient code that avoids _mm256_extract_epi32 with variable indices.

Nevertheless, sometimes it is useful to have a portable (gcc, clang, icc) function, which emulates _mm256_extract_epi32 with variable a index:

The AVX512 conflict detection instructions detect conflicts which would occur when a single scatter instruction writes to the same store location more than once. This is a conflict between different vector lanes in the same instruction.

Atomic operations protect against race conditions which occur when more than one logicalCPU executes a load/store to the same address "at the same time".

Thus you require the conflict detection instructions if your code is vectorized even if it runs single threaded, whereas there is no need for atomic operations until your code is parallelized and executing with many threads.
