Gflops with Simple_matmult and optimized_matmult

Hello,

i run some test to view Gflops on my Radeon 3870

In example simple_matmult i use those arguments : -t -i 10000 and i add the line to have the Width Height Time and Gflops (the same thing that in optimized_matmult)

I have with simple_matmult :

Width   Height  Iterations      Time            Gflops
64      64          10000           0.718681        6.794130

with optimized_matmult:

Width   Height  Iterations      Time            Gflops
64      64          10000           1.084024        4.504341

CPU Time : 15.086446

Can you give me your results with those two samples projects  ??

 i find that's results about GFlops are bad and optimized_matmult takes more time that simple_matmult that's very weird.

Thanks in advance

Jonathan

Edit :

Better result with 1024 height and width and 100 iterations

simple_matmult :

Width   Height  Iterations      Time            Gflops
1024    1024    100             20.184839       9.908427

optimized_matmult

Width   Height  Iterations      Time            Gflops
1024    1024    100             2.112175        94.689126
