Using GPU coprocessor to accelerate computations in 3D MPDATA algorithm
Czestochowa University of Technology –
This talk will address an efficient and portable adaptation of stencil-based 3D MPDATA algorithm to GPU cluster. We propose a performance model, which allows for the efficient distribution of computation across GPU resources. Since MPDATA is strongly memory-bounded, the main challenge of providing a high performance implementation is to reduce GPU global memory transactions. With this purpose, our performance model ensures a comprehensive analysis of transactions based on local memory utilization, sizes of halo areas (ghost zones), data dependencies between and within stencils. The results of analysis performed using the proposed model are number of GPU kernels, distribution of stencils across kernels, as well as sizes of CUDA blocks for each kernel.

Workshop “Metabolism and mathematical models: Two for a tango” – 2nd Edition
Title: Workshop Metabolism and mathematical models: Two for a tango – 2nd Edition
Dates: October 25-26, 2022
Location: This workshop will be held in a virtual way
The topic of this workshop is metabolism in general, with a special focus, although not exclusive, on parasitology. Besides an exploration of the biological, biochemical and biomedical aspects, the workshop will also aim at presenting some of the mathematical modelling, algorithmic theory and software development that have become crucial to explore such aspects.
This workshop is being organised in the context of two projects, both with the Inria European Team Erable. One of the projects involves a partnership with the University of São Paulo (USP), in São Paulo, Brazil, more specifically the Institute of Mathematics and Statistics (IME) and the Institute of Biomedical Sciences – Inria Associated Team Capoeira – and the other involves the Inesc-ID/IST in Portugal, ETH in Zürich and EMBL in Heidelberg – H2020 Twinning Project Olissipo.
The workshop is open to all members of these two projects but also, importantly, to the community in general.
The program and more details are available here.
