Metadata Interpretation Driven Development
Júlio G. S. F. da Costa, Reinaldo A. Petta, Samuel Xavier-de-Souza
Despite decades of engineering and scientific research efforts, separation of concerns in software development remains not fully achieved. The challenge has been to avoid the cross…
Boosting Memory Access Locality of the Spectral Element Method with Hilbert Space-Filling Curves
Roger R. F. Araújo, Lutz Gross, Samuel Xavier-de-Souza
We propose an algorithm based on Hilbert space-filling curves to reorder mesh elements in memory for use with the Spectral Element Method, aiming to attain fewer cache misses, bett…
Performance and Energy Trade-Offs for Parallel Applications on Heterogeneous Multi-Processing Systems
Demetrios A. M. Coutinho, Daniele De Sensi, Arthur Francisco Lorenzon +4
This work proposes a methodology to find performance and energy trade-offs for parallel applications running on Heterogeneous Multi-Processing systems with a single instruction-set…
Auto-tuning of dynamic scheduling applied to 3D reverse time migration on multicore systems
Ítalo A. S. Assis, João B. Fernandes, Tiago Barros +1
Reverse time migration (RTM) is an algorithm widely used in the oil and gas industry to process seismic data. It is a computationally intensive task that suits well in parallel com…
A Scalable Shared-Memory Parallel Simplex for Large-Scale Linear Programming
Demetrios Coutinho, Felipe O. Lins e Silva, Daniel Aloise +2
The Simplex tableau has been broadly used and investigated in the industry and academia. With the advent of the big data era, ever larger problems are posed to be solved in ever la…
Less is More: Exploiting the Standard Compiler Optimization Levels for Better Performance and Energy Consumption
Kyriakos Georgiou, Craig Blackmore, Samuel Xavier-de-Souza +1
This paper presents the interesting observation that by performing fewer of the optimizations available in a standard compiler optimization level such as -O2, while preserving thei…
