The previous article of this mini-series focused on assembly code generation using the hsdis library to intercept the Java JIT emitted output. In this piece, we continue to dive deeper into the execution platform, the physical CPU, where the code runs. Motivation This article aims to show how to use JMH…

This article focuses on installing and using the hsdis library as a decompiler for the JVMs emitted code. Motivation While investigating Java Vector API, it became necessary to understand the generated code to verify specific hypotheses. Unfortunately, the path of sophisticated benchmarking led to a very rocky but successful road: JMH…

Roger, Thank you for your input. I completely agree with your view. but in order to build and explain big algorithms with Vector API one has first to understand the simple examples.

Motivation Recently, I investigated the new Vector API in its third iteration: Java 18: Vector API — Do we get free speed up?! This post is meant to follow up on some interesting findings that I couldn’t answer in the first post. I would like to summarise my findings and show…

Motivation One of my professors at university always tried to convince me: “There is no such thing as free lunch.” But, I have to admit that I never got a free lunch at university, and there is also no magic formula to accelerating a piece of software. Java Vector API provides…
