Hello again,

I compiled one of te examples. I used sparse matix called 02-raefsky3.
I used -vec_type cuda and -mat_type seqaijcuda. 

When I see summary of the operations performed by program there is

MatMult 1 1.0 2.0237e-02 1.0 2.98e+06 1.0 0.0e+00 0.0e+00 0.0e+00  2100
0  0  0   2100  0  0  0   147

Does time of performing MatMult includes memory transfer for loading
matrix in GPU memory or just exact computation time?

Thanks in advance. 
Kuba.
