Fixstars' Yellow Dog Enterprise Linux v6.1 Outperforms the Competition

LOVELAND, COLORADO - 15 April 2009 - Fixstars today announced the release of Yellow Dog Enterprise Linux (YDEL) v6.1. This release introduces important performance improvements as well as new features for the world's only Linux OS built specifically for the Cell Broadband Engine. In addition to providing continued support for Fixstars GigaAccel 180 and IBM QS2x blades, YDEL v6.1 now offers support for the Sony PlayStation3 and IBM JS2x series blades.

"In each release of YDL or YDEL, we focus on one particular area to improve. In YDEL v6.1 while we broadened the hardware support to include the PlayStation 3 and IBM JS blades, our focus was to improve the overall performance of the distribution. YDEL now installs faster, boots faster, and our customers' applications will also benefit from a performance increase," said Owen Stampflee, Fixstars Solutions Director of Engineering.

Results for benchmark tests demonstrate noteworthy performance increases in comparison to other Linux distributions. When running LINPACK (HPL), which is used for the, YDEL v6.1 is 1.5% faster than RHEL on a single blade. The Bonnie++ I/O benchmark shows YDEL as 19.5% faster for NFS than RHEL and 24.8% faster for tmpfs than Fedora.
