Abstract
Non-volatile memory (NVM) is a new hardware technology that provides durable storage at performance similar to that of plain volatile RAM. As such, there is a lot of interest in exploiting this technology to improve the performance of existing disk-bound applications and to find new applications for it. Nevertheless, developing correct programs that interact with non-volatile memory is by no means easy, since mainstream architectures provide rather weak persistency semantics and rather low-level and expensive mechanisms in order to avoid weak behaviors. This creates many opportunities for researchers in programming language semantics, logic, and verification to develop techniques to assist programmers writing NVM programs. This short paper and the associated talk outline the challenges caused by NVM and the research opportunities for PL researchers.
