Babasaheb Naik College of Engineering, Pusad, MS, India. *Corresponding Author: Email- [email protected], [email protected] Received: February 21, 2012; Accepted: March 15, 2012 Abstract- Android is a software stack for mobile devices that includes an operating system, middleware and key applications. Android, an open source mobile device platform based on the Linux operating system. It has application Framework,enhanced graphics, integrated web browser, relational database, media support, LibWebCore web browser, wide variety of connectivity and much more applications. Android relies on Linux version 2.6 for core system services such as security, memory management, process management, network stack, and driver model. Architecture of Android consist of Applications. Linux kernel, libraries, application framework, Android Runtime. All applications are written using the Java programming language. Android mobile phone platform is going to be more secure than Apple’s iPhone or any other device in the long run.

High Performance Computing Systems
High Performance Computing Systems Multikernels Doug Shook Multikernels Two predominant approaches to OS: – Full weight kernel – Lightweight kernel Why not both? – How does implementation affect usage and performance? Gerolfi, et. al. “A Multi-Kernel Survey for High- Performance Computing,” 2016 2 FusedOS Assumes heterogeneous architecture – Linux on full cores – LWK requests resources from linux to run programs Uses CNK as its LWK 3 IHK/McKernel Uses an Interface for Heterogeneous Kernels – Resource allocation – Communication McKernel is the LWK – Only operable with IHK Uses proxy processes 4 mOS Embeds LWK into the Linux kernel – LWK is visible to Linux just like any other process Resource allocation is performed by sysadmin/user 5 FFMK Uses the L4 microkernel – What is a microkernel? Also uses a para-virtualized Linux instance – What is paravirtualization? 6 Hobbes Pisces Node Manager Kitten LWK Palacios Virtual Machine Monitor 7 Sysadmin Criteria Is the LWK standalone? Which kernel is booted by the BIOS? How and when are nodes partitioned? 8 Application Criteria What is the level of POSIX support in the LWK? What is the pseudo file system support? How does an application access Linux functionality? What is the system call overhead? Can LWK and Linux share memory? Can a single process span Linux and the LWK? Does the LWK support NUMA? 9 Linux Criteria Are LWK processes visible to standard tools like ps and top? Are modifications to the Linux kernel necessary? Do Linux kernel changes propagate to the LWK? -

Chapter 1: Introduction Operating System Concepts Silberschatz, Galvin and Gagn Objectives To provide a grand tour of the major operating systems components To provide coverage of basic computer system organization Operating System Concepts 1.2 Silberschatz, Galvin and Gagne What is an Operating System? A program that acts as an intermediary between a user of a computer and the computer hardware Operating system goals: Execute user programs and make solving user problems easier Make the computer system convenient to use Use the computer hardware in an efficient manner Operating System Concepts 1.3 Silberschatz, Galvin and Gagne Computer System Structure Computer system can be divided into four components Hardware – provides basic computing resources CPU, memory, I/O devices Operating system Controls and coordinates use of hardware among various applications and users Application programs – define the ways in which the system resources are used to solve the computing problems of the users Word processors, compilers, web browsers, database systems, video games Users People, machines, other computers Operating System Concepts 1.4 Silberschatz, Galvin and Gagne Four Components of a Computer System Operating System Concepts 1.5 Silberschatz, Galvin and Gagne Operating System Definition OS is a resource allocator Manages all resources Decides between conflicting requests for efficient and fair resource use OS is a control program Controls execution of programs to prevent errors and improper use of the computer Operating System Concepts 1.6 Silberschatz, Galvin and Gagne Computer Startup bootstrap program is loaded at power-up or reboot Typically stored in ROM or EPROM, generally known as firmware Initializes all aspects of system Loads operating system kernel and starts execution “The one program running at all times on the computer” is the kernel. -
Mac OS X: an Introduction for Support Providers
Mac OS X: An Introduction for Support Providers Course Information Purpose of Course Mac OS X is the next-generation Macintosh operating system, utilizing a highly robust UNIX core with a brand new simplified user experience. It is the first successful attempt to provide a fully-functional graphical user experience in such an implementation without requiring the user to know or understand UNIX. This course is designed to provide a theoretical foundation for support providers seeking to provide user support for Mac OS X. It assumes the student has performed this role for Mac OS 9, and seeks to ground the student in Mac OS X using Mac OS 9 terms and concepts. Author: Robert Dorsett, manager, AppleCare Product Training & Readiness. Module Length: 2 hours Audience: Phone support, Apple Solutions Experts, Service Providers. Prerequisites: Experience supporting Mac OS 9 Course map: Operating Systems 101 Mac OS 9 and Cooperative Multitasking Mac OS X: Pre-emptive Multitasking and Protected Memory. Mac OS X: Symmetric Multiprocessing Components of Mac OS X The Layered Approach Darwin Core Services Graphics Services Application Environments Aqua Useful Mac OS X Jargon Bundles Frameworks Umbrella Frameworks Mac OS X Installation Initialization Options Installation Options Version 1.0 Copyright © 2001 by Apple Computer, Inc.

W4118: Multikernel
W4118: multikernel Instructor: Junfeng Yang References: Modern Operating Systems (3rd edition), Operating Systems Concepts (8th edition), previous W4118, and OS at MIT, Stanford, and UWisc Motivation: sharing is expensive Difficult to parallelize single-address space kernels with shared data structures . Locks/atomic instructions: limit scalability . Must make every shared data structure scalable • Partition data • Lock-free data structures • … . Tremendous amount of engineering Root cause . Expensive to move cache lines . Congestion of interconnect 1 Multikernel: explicit sharing via messages Multicore chip == distributed system! . No shared data structures! . Send messages to core to access its data Advantages . Scalable . Good match for heterogeneous cores . Good match if future chips don’t provide cache- coherent shared memory 2 Challenge: global state OS must manage global state . E.g., page table of a process Solution . Replicate global state . Read: read local copy low latency . Update: update local copy + distributed protocol to update remote copies • Do so asynchronously (“split phase”) 3 Barrelfish overview Figure 5 in paper CPU driver . kernel-mode part per core . Inter-Processor interrupt (IPI) Monitors . OS abstractions . User-level RPC (URPC) 4 IPC through shared memory #define CACHELINE (64) struct box{ char buf[CACHELINE-1]; // message contents char flag; // high bit == 0 means sender owns it }; __attribute__ ((aligned (CACHELINE))) struct box m __attribute__ ((aligned (CACHELINE))); send() recv() { { // set up message while(!(m.flag & 0x80)) memcpy(m.buf, …); ; m.flag |= 0x80; m.buf … //process message } } 5 Case study: TLB shootdown When is it necessary?
