Hardware prefetching on IBM’s latest POWER8 processor is able to improve performance of many applications significantly, but it can also cause performance loss for others. The IBM POWER8 processor provides one of the most sophisticated hardware prefetching designs which supports 225 different configurations. Obviously, it is a big challenge to find the optimal or near-optimal hardware prefetc…
Abstract. A clean and simple wet chemical process using dilute aqueous ozone (O3) solution with or without ultrasound (US) was used to functionalize single-walled carbon nanotubes (SWCNTs). Both O3 and O3/US treatments greatly increased the stability of SWCNTs in water. Results of X-ray photoelectron spectroscopy (XPS) showed that the surface oxygen to carbon atomic ratio increased by more tha…
