摘要

介绍了基于Go语言的实时并行编程轻量级框架Go- realtime的设计。Go-RealTime在用户空间中实现，可移植性和效率是重要的设计目标。它充分利用了Go语言易于编程和自然并发模型的优点。通过将Linux api公开给Go，可以为实时任务提供调度，并启用资源预留。我们演示了在32个处理器上使用最小松弛优先(Least Laxity First, LLF)算法调度周期性繁重任务的几乎完全利用率。Go-RealTime凭借其抽象和系统支持，大大简化了多处理器系统上顺序和并行实时程序的设置。

Go-realtime: a lightweight framework for multiprocessor real-time system in user space

We present the design of Go-RealTime, a lightweight framework for real-time parallel programming based on Go language. Go-RealTime is implemented in user space with portability and efficiency as important design goals. It takes the advantage of Go language's ease of programming and natural model of concurrency. Goroutines are adapted to provide scheduling for real-time tasks, with resource reservation enabled by exposing Linux APIs to Go. We demonstrate nearly full utilization on 32 processors scheduling periodic heavy tasks using Least Laxity First (LLF) algorithm. With its abstraction and system support, Go-RealTime greatly simplifies the set up of sequential and parallel real-time programs on multiprocessor systems.
