Post date: June 22, 2006, 15:06 Category: Miscellaneous Views: 6206 Comments
Tutorial quote: Ubuntu has become the most popular Linux distribution for new Linux users. It's easy to install, easy to use, and usually "just works." But moving to a different operating system can be confusing, no matter how well-designed it is. Here's a list of tips that might save you some time while you're getting used to Ubuntu.

Considerations for the system architect: Performance

Post date: April 20, 2005, 10:04 Category: Miscellaneous Views: 2889 Comments
Tutorial quote: For many developers and engineers, performance is often an afterthought. But when a product functions as designed and has proven stability and the right feature mix, success in the marketplace often depends upon performance. Architectural decisions define the ultimate feasible performance of any product. In this article, learn how performance-monitoring technology initially developed for mainframes can help you improve your own code's performance.

Application optimization with compilers for Linux on POWER

Post date: May 23, 2005, 16:05 Category: Optimizing Views: 2762 Comments
Tutorial quote: The Linux on POWER platform offers more than one option to produce binary C/C++ code. In addition to supporting both 32- and 64-bit runtime environments simultaneously, Linux on POWER has two compiler collections. The GNU Compiler Collection, or GCC, is consistent with other Linux implementations with specific exceptions for the POWER architecture. GCC is the leading compiler for portability but also features a number of performance enhancements for optimizing code. The IBM XL C/C++ compiler for Linux on POWER is derived from the high performance compiler for AIX but uses the GNU linker and assembler to create ELF objects that are fully compatible with objects produced by GCC. This document provides side-by-side comparisons of how these two compilers are controlled, overviews of what the compilers are capable of, in terms of optimization, and tips for writing code that is more easily optimized with either of these compilers.

Choosing an I/O Scheduler for Red Hat Enterprise Linux 4

Post date: July 18, 2005, 22:07 Category: Benchmarks Views: 7483 Comments
Tutorial quote: The Linux kernel, the core of the operating system, is responsible for controlling disk access by using kernel I/O scheduling. Red Hat Enterprise Linux 3 with a 2.4 kernel base uses a single, robust, general purpose I/O elevator. The 2.4 I/O scheduler has a reasonable number of tuning options by controlling the amount of time a request remains in an I/O queue before being serviced using the elvtune command. While Red Hat Enterprise Linux 3 offers most workloads excellent performance, it does not always provide the best I/O characteristics for the wide range of applications in use by Linux users these days. The I/O schedulers provided in Red Hat Enterprise Linux 4, embedded in the 2.6 kernel, have advanced the I/O capabilities of Linux significantly. With Red Hat Enterprise Linux 4, applications can now optimize the kernel I/O at boot time, by selecting one of four different I/O schedulers.
