Advanced Vector Extensions (AVX) stress generator : AVX-SG

Advanced Vector Extensions (AVX) are extensions to the x86 instruction set architecture for microprocessors for SIMD technology. This project shows how to use the AVX instructions from the instructions from the C code prespective. Using templates the users of AVX-SG can generate stress code for latest x86-64 platforms ( including BFLOAT16 and VNNI )

The code include examples for:

• SSE technology
• AVX2 technology
• AVX-512 technology

How to build these examples

make

How to build these static

Create static binary which runs across multiple distros

make static

How to clean

make clean

How to assign a cpu to run an example :

./add & taskset -cp 0 <PID>

How to run all examples in all CPUs available:

./run-all.sh

If you want to kill all the processes running in the system, you can use:

pkill -f build/<file>

instead of kill -9 <PID>

How to run these examples w/o HW that support instructions (like AVX-512 or VNNI)

Download the Intel Software Development Emmulator

On LINUX* OS you can run your favorite shell under the control of Intel SDE:

path-to-kit/sde(64) -- /bin/tcsh

And everything you run from there will be run under the control of Intel SDE.

For example running the compiled examples

IMPORTANT: Is better to compile in other shell and not under the SDE shell , just use the SDE to run the examples

Apart from:

VPDPBUSD __m128i _mm_dpbusd_epi32(__m128i, __m128i, __m128i);

Extend VNNI to

VPDPBUSD __m256i _mm256_dpbusd_epi32(__m256i, __m256i, __m256i);
VPDPBUSD __m512i _mm512_dpbusd_epi32(__m512i, __m512i, __m512i);
