Description:

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
to use 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 systems
Ganglia, 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.
