# Capgemini SIMD tasks

Assembly tasks are implemented for the Linux environment (WSL) and NASM assembler.

C++ tasks are implemented for the Linux environment (WSL) and gcc compiler (g++)

Tasks list:

- vector addition;

- vector addition with aligned dynamic memory allocation;

- dot product;

- matrix multiplication;

- substring search.

## Getting Started

### Work environment preparation

`git clone https://github.com/denyskryvytskyi/capgemini-simd`

`sudo apt update`

`sudo apt install nasm gdb gcc g++`

### Pure assembly program compilation and linking

`nasm -f elf64 task_.asm`

`ld -o task_ task_.o`

### Assembly with extern C function program compilation and linking

`nasm -f elf64 task_.asm`

`gcc task_.o -o task_ -no-pie`

### C++ program compilation

#### Without optimization flags:

`g++ -o task_ task_.cpp`

#### With optimization flags:

**SSE**

`g++ -Wall -o task_ task_.cpp -O3 -msse2`

**AVX integer calculations**

`g++ -Wall -o task_ task_.cpp -O3 -mavx2`

**AVX float calculations**

`g++ -Wall -o task_ task_.cpp -O3 -mavx2 -mfma`

### Run

`./task_`
