Abstract
High-capacity non-volatile memory (NVM) is a new main memory tier. Tiered DRAM+NVM servers increase total memory capacity by up to 8x, but can diminish memory bandwidth by up to 7x and inflate latency by up to 63% if not managed well. We study existing hardware and software tiered memory management systems on the recently available Intel Optane DC NVM with big data applications and find that no existing system maximizes application performance on real NVM.
