CILAMCE 2011

Pelo terceiro ano consecutivo, estaremos organizando um simpósio sobre supercomputação com placas gráficas no CILAMCE.

O CILAMCE é o Congresso Ibero-Latino-Americano de Métodos Computacionais em Engenharia, e em 2011 está na sua 32ª edição. O congresso acontecerá em Ouro Preto – MG, entre 13 e 16 de Novembro deste ano.

A deadline para submissão de resumos é 1º de Maio. Preparem seus trabalhos! Vamos nos encontrar em Ouro Preto para discutir GPGPU!

Summary

After a long period of steady growth, desktop commodity computer architecture has reached its ceiling on computing performance. Further progress is no longer enabled by growth in core clock rates, but by growth in parallelism. Many articles have been presented in the last editions of CILAMCE and MECOM on the use of multi-cored computing applied to a variety of problems. Furthermore, there is a growing trend toward parallel computation on the recently created general-purpose graphics hardware (GPGPU) [1]. Due to its architecture, the GPU is specially well-suited to address problems that can be expressed as data-parallel computations with high arithmetic intensity (the ratio of arithmetic operations to memory operations) [2]. Recent works have been shown astonishingly fast computations. For instance, papers on the use of GPGPU for computational mechanics have been reporting performances up to 100 times faster than CPUs for solution of linear systems, and around 900 times faster for numerical solution of infinite oscillatory integrals [3]. The first edition of this mini-symposium on CILAMCE 2009 has shown that the GPU has been investigated by researches of a very broad range of subjects in computational modeling with considerable gains in performance. The idea of the present mini-symposium is to gather researchers working on HPC tasks using GPGPU systems, aiming to discuss the state of the art issues, exchange experiences and solutions for existing implementation strategies and problems.

CILAMCE 2009

Organizamos um mini-simpósio sobre supercomputação com GPU no 30º Congresso Ibero-Latino-Americano de Métodos Computacionais em Engenharia – CILAMCE 2009. O objetivo era reunir as pessoas que estão trabalhando com esse assunto no Brasil.

O resultado foi melhor do que esperávamos. Treze resumos foram submetidos, e seis trabalhos foram apresentados. Veja os trabalhos apresentados:
