Title:
Using GPUs in SU2 codeAbstract:
GPUs may be used to reduce the required wall clock time in SU2 calculations. In this talk some early experiments on the usage of one GPU in implicit RANS calculations with SU2 are given. As the parallelism degree for the calculations is rather limited, one CPU thread will not be able to saturate several or even one GPU. Therefore this work focusses on sharing one or few GPUs by several threads, instead. Currently one step in the preconditioning of the linear equation solver has been analyzed there classical Gauss-Elimination of very small dense matrices has to be performed for all nodes repeatedly. Preliminary results and ideas for further GPU usage will be given.
