Sun architects are making groundbreaking progress towards sophisticated synchronization support for multicore systems, find Dave Dice, Yossi Lev, Mark Moir, Dan Nussbaum, and Marek Olszewski. In their research for a Sun Labs technical report on commercial hardware transactional memory (HTM), the men report on a number of promising results using HTM to improve performance in a variety of contexts, in addition to lessons learned on more effectively using the feature.
In his contrarian minds interview with David Vengerov, writer Al Riske characterizes the Sun Labs researcher as "part of an emerging consensus that large-scale systems need to be self-managing and self-optimizing." The complexity of systems is so vast that setting tuning parameters has become all but impossible to accomplish perfectly. "The only thing people can do now to make these systems work well is to set by hand multitudes of different parameters and policies," Vengerov told Riske.
For handling bugs, Cristina Cifuentes, a senior staff engineer in Sun Labs discusses "the Parfait Project." The Parfait Project is named after the dessert because it takes a multi-layered approach to bug checking. The building of this layered bug checker is an attempt at providing an efficient tool for checking bugs and reducing the amount of time spent.
Within the Open Source Community, the updated version of the Hardware Activity Reporter (HAR) Version 2.0 is available for download. The original version 1.0 was created in 2001 by the Sun ISV Engineering group for Solaris 8 and has since been enhanced by the developer community.
The China Innovation Program for Students (CHIPS) is a student development program providing mentoring and training on open source technologies. Sponsored by Sun and the Ministry of Education of China, CHIPS will invite technology students from 10 Chinese universities to leverage Sun's portfolio of open source, virtual and collaborative technology solutions to build an online virtual collaboration site. Divided into teams, the best one will be flown to Sun's corporate headquarters for a one week hosted stay where they will meet with Sun technologists for additional mentoring programs.
