LOVELAND, Colorado – 30 November 2005 – Terra Soft Solutions, the leading developer of integrated Power Architecture Linux solutions is pleased to announce its role in COLSA Corporation’s success with MACH5, the world’s largest Apple Xserve-based cluster.

In June 2004, COLSA, located in Huntsville, Alabama, began construction of their 1,566-node Apple Xserve G5 cluster for the United Stated Army. In late 2004, COLSA contracted Terra Soft to help prepare a system-wide Linux installation using the then beta Y-HPC cluster construction and management suite.

Terra Soft’s David Smith worked on-site with COLSA engineers for three days in order to prepare a multi-tier system first for rapid node replication and secondly to maximize system performance. Significant gains were recognized with their combined efforts: the Top500.org benchmark, Linpack, achieved 16.18 Tflops on the Xserve, vaulting it to the 15th fastest computer in the world.

Jeff Highfield, senior engineer at the Huntsville COLSA facility states, “Terra Soft was highly responsive to our needs, providing on-site assistance with little advance notice and on-going support for the past year. While we ultimately used a mixture of Terra Soft’s offerings and in-house developed code, the Terra Soft team and their Y-HPC product provided the foundation for our exceptional placement on the Top500.org list.”

COLSA has shown their continuing dedication to researching the best possible solution for their cluster and has devoted significant resources to the effort. Software and systems engineers at COLSA have committed their time and two full racks of G5 Xserves to assist Terra Soft with on-going Y-HPC development and testing. Terra Soft’s co-founder & CEO Kai Staats offers, “We are pleased to continue to work with COLSA to not only improve their cluster performance, but also further the real world value of Y-HPC as a cluster construction and management suite.”

The next version of Y-HPC will be distributed to YDL.net Pro account holders following the near-future release of Yellow Dog Linux v4.1.
