    1111Comment(20100812): With the latest Catalyst 10.7, slow transfer speed for GPU to CPU memory is gone. We have roughly ~ 6 GB/sec for both directions. However, it just represents practical maximum transfer speed with a combination of Cypress and X58 chipset. The actual transfer speed from/to the main memory is rather slow ~ 2.5 GB/sec at most with the pinned memory allocation. This is the problem!

     13Update(20100820): We have implemented a proper treatment of alpha and beta. In the latest plot, we compare our results with ACML-GPU 1.1 and MAGMA BLAS 0.3 running on Fermi.
