IREE/MLIR/Linalg tutorial

Introduction

This tutorial is simultaneously about IREE, MLIR, and specifically the MLIR Linalg dialect.

What is MLIR?

MLIR is a programming language, but MLIR in itself is almost just an empty shell. What it really provides is a framework allowing to define MLIR dialects which are where the features come from.

ARM’s Scalable Vector Extensions: A Critical Look at SVE2 For Integer Workloads

Scalable Vector Extensions (SVE) is ARM’s latest SIMD extension to their instruction set, which was announced back in 2016. A follow-up SVE2 extension was announced in 2019, designed to incorporate all functionality from ARM’s current primary SIMD extension, NEON (aka ASIMD).

Despite being announced 5 years ago, there is currently no generally available CPU which supports any form of SVE (which excludes the [Fugaku supercomputer](https://www.fujitsu.com/global/about/innovation/

C++ : Polymorphic inheritance without vtable

Inheritance and Virtual Table are often used to create interface in C++ polymorphic class
What if ... there were another way to do this ?
easier, cleaner, faster and more reliable
This article explains how to use CRTP, [std::variant](https://en.cppreference.com/w/cpp/utility/variant and std::visit to increase code performance.

Prerequisites

Before you continue, if you don't know what IMGUI is don't bother reading this post, just ignore it, don't write anything in comments section, etc. If you're curious about IMGUI see bottom of this post, otherwise continue whatever you were doing, this post it's not for you. Thanks!

If you know what IMGUI is, for context read following presentations and blog posts:

	if (${CMAKE_HOST_SYSTEM_PROCESSOR} STREQUAL "AMD64")
	set(GLSL_VALIDATOR "$ENV{VULKAN_SDK}/Bin/glslangValidator.exe")
	else()
	set(GLSL_VALIDATOR "$ENV{VULKAN_SDK}/Bin32/glslangValidator.exe")
	endif()

	file(GLOB_RECURSE GLSL_SOURCE_FILES
	"shaders/*.frag"
	"shaders/*.vert"
	)

	ssize_t read(int fd, void *buf, size_t count);

	ssize_t write(int fd, const void *buf, size_t count);
