An in-depth look at Google’s first Tensor Processing Unit (TPU) [Laurent Steff]
vendredi 16 juin 2023
« Do you have a recent NVidia graphic card with Raytracing (RTX) ? If yes chances are your GPU embeds a TPU (Tensor Processing Unit) to accelerate the RayTracing with machine learning (Deep Learning Super Sampling, DLSS). OK, enough of acronyms, and let's dive deep in what those Tensor Process Unit are, with an in depth explanation of what is inside the now legacy first version. Back in the days Google really though out of the box to tackle energy efficiency for Machine Learning. With for example 8 bits registers, and a way of loading registers in matrix multiplication unit inspired from biology: the "systolic array". From the article: "The design is called systolic because the data flows through the chip in waves, reminiscent of the way that the heart pumps blood".  »

A two parts tutorial in C to learn how to offload computation to your Nvidia GPU [Laurent Steff]
jeudi 10 mars 2022
« CUDA is both a platform and an API that permit to offload computation to Nvidia GPUs. This hands-on like tutorial allow C (and with little effort C++) programmers to make their first step on Nvidia CUDA programming, from printing "Hello, world" to adding two million-entries vectors. Be wary though, as the right CUDA-Toolkit installation may be time consuming, depending on the platform, your Nvidia GPU, its installed driver ... it may be easier if some have access to GPU enabled nodes on clusters.  »

Nvidia developed a radically different way to compress video calls [Sébastien]
jeudi 26 novembre 2020
« NVidia a annoncé un SDK qui permet de limiter la bande passante en visioconférence en ayant recours à des techniques liées à l'apprentissage plutôt qu'à des compressions classiques. L'article explique très pédagogiquement le principe des réseaux GAN.  »

The coronavirus pandemic turned Folding@Home into an exaFLOP supercomputer [Sébastien]
mercredi 15 avril 2020
« L'application Folding@home a enregistré un regain d'intérêt très fort avec la crise du Covid 19, surtout après un appel à contributions lancé par Nvidia pour mettre à contribution des ressources GPU.  »
