Hi,

I ran ex2.c with a matrix from 512x512 grid. 
I set CG and Jacobi for the solver and preconditioner. 
GCC-4.4.4 and CUDA-3.1 are used to compile the code.
BLAS and LAPAKCK are not optimized.

MatMult
Fermi: 		1142 MFlops
1 core Istanbul:	420 MFlops

KSPSolve:
Fermi:			1.5 Sec
1 core Istanbul:	1.7 Sec
