Hi all,
i ran time-averaged coulomb potential evaluations (downloaded from vmd
cuda website) and got more than 500 speedup on nvidia 9800 gpu vs cpu.
gpu speed 265.45 GFLOPS
cpu(4 threads) speed 0.497122 GFLOPS

how is it possible? According to John Stone presentations the speedup
is expected to be at around 30 or 100.
