"Performance comparison of Cell Processor to Traditional Dual or Quad-Core Processor for Scientific Computing"
Abstract: "Cell is a microprocessor architecture developed by STI, an alliance by SONY, Toshiba and IBM. The project mainly deals with comparison of Cell Processor and its architecture, against the traditional multi-core microprocessor technology for scientific computing. A scientific code, numerically modeling the astrophysical process of a small star being captured by a black hole is used for data collection. In essence, it is a linear hyperbolic PDE (partial differential equation) solver in 2+1 dimensions. The code uses a Lax-Wendroff numerical scheme to evolve the given initial data and thus obtain a solution to the PDE. The PDE is inhomogeneous, i.e. it has a source-term that is mathematically very complex. This source-term calculation, which occurs twice at every time-step, is the most computationally intensive part of this code and would benefit tremendously from vectorization/parallelization. The goal of the project is to use the Cell's SPEs to parallelize this part of the computation and test performance gain compared to a traditional multi core architecture. Various other bench marks were also carried out to validate the cell processor's performance over the traditional multi-core architecture." |
