The first barrier that a new Linux user has to face is the overwhelming number of flavors that this operating system has. These flavors are commonly known as distros (from distribution), and to date there are more than three hundred active distros to choose from. So, how to choose one? You can choose the most popular at the moment, or take heed of what your friend says, but are you sure that this is the one that you need? Making the wrong decision on this matter is behind a good number of disappointments with this operating system. You need to choose the distro that is right for you and your needs. Introducing Linux Distros teaches you the pros and the cons of the most frequently used distros in order to find the one that is right for you. You will explore each distro step by step, so that you dont have to endure hours of web surfing, countless downloads, becoming confused by new concepts and, in the worst cases, reading complex and marathon installation guides. You will benefit from the authors long-term experience working with each distro hands on, enabling you to choose the best distro for your long-term needs. Linux offers us a wonderful open source alternative to proprietary software, and using Introducing Linux Distros you can decide how to best make it work for you. Start exploring the open source world today. Jose Dieguez Castro is a senior systems administrator, currently working as a freelance consultant.

Unix in 24 Hours, Sams Teach Yourself:Covers OS X, Linux, and Solaris Dave Taylor
To the outside world, a ´´supercomputer´´ appears to be a single system. In fact, it´s a cluster of computers that share a local area network and have the ability to work together on a single problem as a team. Many businesses used to consider supercomputing beyond the reach of their budgets, but new Linux applications have made high-performance clusters more affordable than ever. These days, the promise of low-cost supercomputing is one of the main reasons many businesses choose Linux over other operating systems.This new guide covers everything a newcomer to clustering will need to plan, build, and deploy a high-performance Linux cluster. The book focuses on clustering for high-performance computation, although much of its information also applies to clustering for high-availability (failover and disaster recovery). The book discusses the key tools you´ll need to get started, including good practices touse while exploring the tools and growing a system. You´ll learn about planning, hardware choices, bulk installation of Linux on multiple systems, and other basic considerations. Then, you´ll learn about software options that can save you hours--or even weeks--of deployment time.Since a wide variety of options exist in each area of clustering software, the author discusses the pros and cons of the major free software projects and chooses those that are most likely to be helpful to new cluster administrators and programmers. A few of the projects introduced in the book include: MPI, the most popular programming library for clusters. This book offers simple but realistic introductory examples along with some pointers for advanced use. OSCAR and Rocks, two comprehensive installation and administrative systems openMosix (a convenient tool for distributing jobs), Linux kernel extensions that migrate processes transparently for load balancing PVFS, one of the parallel filesystems that make clustering I/O easier C3, a set of commands for administering multiple systemsGanglia, OpenPBS, and cloning tools (Kickstart, SIS and G4U) are also covered. The book looks at cluster installation packages (OSCAR&Rocks) and then considers the core packages individually for greater depth or for folks wishing to do a custom installation. Guidelines for debugging, profiling, performance tuning, and managing jobs from multiple users round out this immensely useful book.
