POSIX-based Operating System in the environment of NVM/SCM memory
Abstrak
Modern Operating Systems are typically POSIX-compliant. The system calls are the fundamental layer of interaction between user-space applications and the OS kernel and its implementation of fundamental abstractions and primitives used in modern computing. The next generation of NVM/SCM memory raises critical questions about the efficiency of modern OS architecture. This paper investigates how the POSIX API drives performance for a system with NVM/SCM memory. We show that OS and metadata related system calls represent the most important area of optimization. However, the synchronization related system calls (poll(), futex(), wait4()) are the most time-consuming overhead that even a RAMdisk platform fails to eliminate. Attempting to preserve the POSIX-based approach will likely result in fundamental inefficiencies for any future applications of NVM/SCM memory.
