7 Embedded Operating Systems Claudio Scordino1, Errico Guidieri1, Bruno Morelli1, Andrea Marongiu2,3, Giuseppe Tagliavini3 and Paolo Gai1 1Evidence SRL, Italy 2Swiss Federal Institute of Technology in Zurich (ETHZ), Switzerland 3University of Bologna, Italy In this chapter, we will provide a description of existing open-source operating systems (OSs) which have been analyzed with the objective of providing a porting for the reference architecture described in Chapter 2. Among the various possibilities, the ERIKA Enterprise RTOS (Real-Time Operating System) and Linux with preemption patches have been selected. A description of the porting effort on the reference architecture has also been provided. 7.1 Introduction In the past, OSs for high-performance computing (HPC) were based on custom-tailored solutions to fully exploit all performance opportunities of supercomputers. Nowadays, instead, HPC systems are being moved away from in-house OSs to more generic OS solutions like Linux. Such a trend can be observed in the TOP500 list [1] that includes the 500 most powerful supercomputers in the world, in which Linux dominates the competition. In fact, in around 20 years, Linux has been capable of conquering all the TOP500 list from scratch (for the first time in November 2017). Each manufacturer, however, still implements specific changes to the Linux OS to better exploit specific computer hardware features. This is especially true in the case of computing nodes in which lightweight kernels are used to speed up the computation. 173 174 Embedded Operating Systems Figure 7.1 Number of Linux-based supercomputers in the TOP500 list. Linux is a full-featured OS, originally designed to be used in server or desktop environments. -

An "embedded system" is any computer system or computing device that performs a dedicated function or is designed for use with a specific embedded software applica tion. Embedded systems may use a ROM-based operating system or they may use a disk-based system, like a PC. But an embdddbedded sys tem is no t usa ble as a commercillially v ibliable substitute for general purpose computers or devices. 3 Aspects of embedded system design 4 Metrics •Performance can be measured in multiple ways –Latency vs. throughput –Average vs. worst-case vs. best-case –Peak vs. sustained •Power/energy –Power consumption is important for heat generation –Energy consumption is important for battery life –ItIntegra tdted me titrics suc h as Energy-De lay Pro duc t (EDP) •Cost –Des ign time vs. life time •Reliability –Avail a bility, depen da bility, performabilit y 5 Hardware/software codesign •Goals –Optimizing design process –Oppggtimizing design •Tasks –Cospecificationand comodeling –Codesign –Cosynthesis, optimization, interfacing –Verification 6 Codesign flow 7 What makes a good Embedded OS?

Comparing Windows NT, Linux, and QNX As the Basis for Cluster Systems
Comparing Windows NT, Linux, and QNX as the Basis for Cluster Systems Avi Kavas Dror G. Feitelson School of Computer Science and Engineering The Hebrew University, 91904 Jerusalem, Israel Abstract Clusters use commodity hardware and software components to provide an environment for parallel processing. A major issue in the development of a cluster system is the choice of the operating system that will run on each node. We compare three alternatives: Windows NT, Linux, and QNX — a real-time microkernel. The comparison is based on expressive power, performance, and ease-of-use metrics. The result is that none of these systems has a clear advantage over the others in all the metrics, but that each has its strong and weak points. Thus any choice of a base system will involve some technical compromises, but not major ones. 1 Introduction Rapid improvements in network and processor performance are causing clustered commodity workstations and PCs to become an increasingly popular platform for executing parallel applica- tions. In the past, Unix was used as the platform for almost all parallel systems implementations. Recently, however, it is becoming more common to use Windows NT as the base platform. The decision which operating system to use involves many considerations, including the oper- ating system’s cost and personal experience with the different systems. But there are also technical implications. Our goal is to illuminate these technical issues, by providing a broad comparison of the capabilities and characteristics of the different systems. Throughput, the emphasis is on those features deemed to be important for the implementation of computational clusters. -
