IBM’s BlueGene Hits Warp Speed

The IBM BlueGene/L supercomputer at Lawrence Livermore National Laboratory just got a fresh dose of steroids. Its number-crunching speed has been pumped up to a phenomenal 183.5 trillion calculations every second. That's 183.5 teraflops in geek-speak -- double the 92 teraflops world record that BlueGene set just six months ago.

Perl Parser Performance

C/C++ parsers, such as libxml2 or Xerces C++ have entered the scene, and so have their Perl extensions. Perl XML folks have developed Perl SAX, a Perlish counterpart of Java SAX interface. Currently, CPAN contains several parsing modules. This article compares the performance of five free PerlSAX 2 parsers available from CPAN. Older XML::Parser is also included to serve as a baseline.

Performance of Java versus C++

This article surveys a number of benchmarks and finds that Java performance on numerical code is comparable to that of C++, with hints that Java's relative performance is continuing to improve. Then they describe clear theoretical reasons why these benchmark results should be expected.

Power Mac G5 Trails Opteron on Media Benchamrks

"The Power Mac G5 is a formidable machine, representing a giant leap in performance over the G4. But the 64-bit transition so far only represents a small step. Even though there's not much of a benefit from 64-bit computing yet, this marks the beginning of a new era for Apple, where the 64-bit world will enable new capabilities for the content creation community" the reviewer concludes in his benchmark article.

Benchmarking Filesystems: JFS, XFS, ReiserFS, ext3

"The conclusion is obvious by the "Total Time For All Benchmarks Test." The best journaling file system to choose based upon these results would be: JFS, ReiserFS or XFS depending on your needs and what types of files you are dealing with. I was quite surprised how slow ext3 was overall, as many distributions use this file system as their default file system. Overall, one should choose the best file system based upon the properties of the files they are dealing with for the best performance possible!" Read the whole article at the LinuxGazette.

Benchmark: Linux 2.6 and Hyper-Threading

"Anyone who's ever set out to perform Linux benchmarks quickly realizes the difficulties involved in such an undertaking, not only with the availability of quality benchmarks (or lack thereof), but also in the way the test system(s) are configured. Most of the Linux benchmarks that I see on hardware review sites are simple things like kernel compiles or povray... maybe a game benchmark or two." 2CPU.com gets serious over Linux benchmarking on the web.

SPARC Optimizations With GCC

In continuing with my articles exploring the my SPARC-based Sun Ultra 5, I'm going to cover the topic of compiler optimizations on the SPARC platform. While many are familiar with GCC compiler optimizations for the x86 platform, there are naturally differences for GCC on SPARC, and some platform-specific issues to keep in mind.
