Energy-efficient and high-performance software architecture for storage class memory
AbstPactAhfe RAM is RAM which has been made as reliable as a disk. W e coI1sider the problem of buffer management in partially safe buffers, i.e., butlers which contain both safe RAM and volatile RAM. Buffer managemnt techniques for partially safe buffers explicitly consider the safety of memory in deciding which data to place in the buffer, where to place it, and when to copy updaks back to the disk. W e present techniques for managhg such buffers and study their per formauce using trace-driven simulations.
