Portable Software Optimizations for Current and Future Memory-Hierarchies Architectures by João Ferreira Alves PhD thesis proposal presentation and discussion. Date: 2023-Jan-30 Time: 15:00 Room: Zoom Abstract: The main goal of this research is to develop high-performance portable software optimizations that minimize data movements between the various levels of cache in current and future CPU architectures, with a focus on matrix operations. This will help to reduce the performance gap between the processor and main memory, particularly for problems that involve large matrices and exhibit poor data locality. To achieve this goal, we will focus on the properties of Hilbert space-filling curves, which generally present better spatial and temporal locality than Peano and Z-order curves.
