Abstract

A Roe's flux-difference splitting scheme has been implemented using the NVIDIA CUDA architecture andhas been applied to solve the two-dimensional compressible Euler equations. Different standard test caseshave been considered in order to estimate the speed-up of GPU computing with respect to CPU calculation.A detailed description of the kernel configuration has been provided and a theoretical analysis of theGPU execution time as a function of the number of threads managed by the kernels is also reported. Theloss of performance has been fully described consequent to the use of zero-copy memory. Significantperformance improvements have been obtained by using a more recent GPU and CUDA Toolkit. A testcase on multi-GPU architecture has been presented in the domain decomposition approach.
