Dominoes Talk in GTC 2016

In the last week I attended the GPU Technology Conference (GTC), which took places in San Jose, California. As expected, a lot of information and research have been presented, including the new GPU model to be release, called Pascal. I will address some of these new functionalities in another post. Dominoes has been presented on the GTC and …

GPU Technology Conference!

Last year I submitted a talk proposal about Dominoes to GTC, the biggest GPU conference in the word brought by Nvidia. Dominoes is an application that was developed as part of my Ph.D. research for allowing exploratory data analysis over repositories using GPU. After the period of analysis, I received an email saying that it was …

Blog to come alive!

Hi all, Since a long time without updating my blog, I intend to make it alive again! Since my last post, a lot of things happened, which I intend to describe further on other posts! I had been really busy with all stuffs happening at the same time, such as finishing my Ph.D., getting to …

Coalesced Memory in CUDA

As I always say in my CUDA lectures, taking care of accessing global memory in CUDA is always needed. In this article, Mark Harris presents an study about the consequences of misaligned access in this kind of memory. As is possible to see, absent from stride access, newest GPU architecture are becoming less sensitive to …

CUDA Lecture on Uberlândia

In the last Thursday and Friday, I went to Uberlândia (MG) to present a lecture about CUDA in the XV Encontro de Modelagem Computacional (XV Computational modeling meeting) , invited by professor Fran Sergio Lobato. The conference was good and the audience very interested about the topic covered. Unfortunately, due to time, only the basic …

Main web site updates

With too many tasks to do for my thesis that I’m going to present at the end of this semester, I did not much time to post news in the blog. In a short time that I had the last weekend, I’ve update my main web site with a new layout and last game’s project …

Fluid Simulation

Today I’ve finished my fluid implementation using SPH (Smoothed Particle Hydrodynamics) method for my thesis master degree. As can be seen in the video below, I archived two way coupling between fluids and rigid bodies. At this time, I need to work in GPU optmization to allow for more particles to be simulated. Also, I …

"Direção Defensiva" Presentation

This week, the game “Direção Defensiva” was presented at a government conference. As I said in an old post, this game was developed to help people driving better as the player have to obey the traffic rules like stop at traffic light,  don’t exceed the road’s speed limit, and so on. At the same time, …
