It can be used for wider applications than the range of applications of previous GRAPE systems. We implemented libraries for gravitational N-body simulations and matrixmatrix multiplications(DGEMM) on the GRAPE-DR system, we report the performance of these libraries as of the end of June 2009. we evaluated performances of these libraries on a single PC with a GRAPE-DR accelerator card.
