Cellular Genetic Algorithm on Graphic Processing Units
The availability of low cost powerful parallel graphic cards has estimulated a trend to implement diverse algorithms on Graphic Processing Units (GPUs). In this paper we describe the design of a parallel Cellular Genetic Algorithm (cGA) on a GPU and then evaluate its performance. Beyond the existing works on masterslave for fitness evaluation, we here implement a cGA exploiting data and instruc...

متن کاملAvoiding Communication in Two-Sided Krylov Subspace Methods
Preconditioning Krylov Subspace Methods are commonly used for solving linear system Standard implementations are communication-bound due to required SpMV and orthogonalization in every iteration Solution: rearrange algorithms to perform s iterations at a time without communicating (s-step methods) SpMV in each iteration is replaced with a call to the Matrix Powers Kernel, which performs...
