Concurrency and Operating Systems, Processors, and Programming Languages

Abstract

The main content of our research is to optimize and improve the concurrency of the system from the three aspects of operating system, processor and programming language. Previous solutions have focused on hardware techniques to improve concurrency. Our goal is to solve the problem of resource occupancy and contention through algorithms, data structures, optimization interrupts, and optimization of process and coroutine scheduling. In the final ideal case, the finite-state machine switching code generated by the compiler can be used to switch the coroutines in the same process. For threads, the thread code provided by the kernel does the switching. The asynchronous system call is optimized to automatically generate the corresponding system call request code according to the execution compiler and maintain the coroutine control block data structure. This is also the most difficult part of this research.
