GT430の実効性能（単精度）をnbodyで計測

$ /home/t_azu/NVIDIA_GPU_Computing_SDK/C/bin/linux/release/nbody -benchmark
Run "nbody -benchmark [-n=<numBodies>]" to measure perfomance.
	-fullscreen (run n-body simulation in fullscreen mode)
	-fp64       (use double precision floating point values for simulation)

2048 bodies, total time for 10 iterations: 9.161 ms
= 4.578 billion interactions per second
= 91.564 single-precision GFLOP/s at 20 flops per interaction
