The Future of the SPARC T5 in Oracle's Big Iron Lineup [27510]
Timothy Prickett Morgan Reports from Hot Chips
Reporting on this year's Hot Chips event in Cupertino, CA, Timothy Prickett Morgan speculates on the future of the SPARC T5 chip in Oracle's apparent growing interest in big iron featuring multithreaded processors in terms of cores and sockets. In his view, the scalability enhancements coming from the SPARC T5 machines, sporting faster cores that can do superior single-threaded work, will be big enough for all but the absolutely largest Solaris workloads. Prickett Morgan devotes a substantial part of his article to looking at the history of the SPARC T3, T4 and T5 chips and their family resemblances.

Revision to SPARC Architecture Released [27424]
Essential to Understanding the Operation of the SPARC Processor
Darryl Gove draws attention to the release of the updated "Oracle SPARC Architecture 2011," a document essential for those interested in the behavior of a SPARC processor. This publication supersedes the SPARC v9 book, which was published in the 90s. Describing its scope, the document collects in one volume the nonprivileged (Level 1) architecture from SPARC V9; most of the privileged (Level 2) architecture from SPARC V9; and provides more in-depth coverage of all SPARC V9 features. Moreover, the book includes all of the architectural extensions (beyond SPARC V9), developed through the processor generations of UltraSPARC III, IV, IV+ and T1.

Oracle's SPARC T4 Chip Called Twice as Fast as SPARC T3 [24466]
Expect a Hot Property in this Chip, Timothy Prickett Morgan Writes
In the view of Timothy Prickett Morgan, writing in "The Register," "The SPARC T4 processor that Oracle expects to ship before the end of December ... is probably the most important chip that either Sun or Oracle has put into the field since the dual-core UltraSPARC-IV+ 'Panther'...." The new SPARC T core has a feature called the critical thread API that allows a high priority application to grab one thread on a core and hog all of the resources on that core to significantly boost performance of that single thread. The SPARC T4 will have double the per-thread performance of the T3 chip it will replace, according to Prickett Morgan, quoting Oracle sources.

Oracle Releases Information on the New SPARC T4 and Beta program [24355]
Five Times Faster than SPARC T3
Information on the beta program for Oracle's forthcoming SPARC T4 processor caught the attention of blogger Henkis, who draws on Oracle's own releases to furnish information on the release. "The aim here was to develop a processor core that would provide high-speed, single-thread performance while also addressing the needs of applications that benefit from the high efficiency and throughput of multithreaded cores. The SPARC T4 is up to five times faster than the SPARC T3 for single-threaded functions," says Rick Hetherington, vice president of hardware development at Oracle. "It's breakthrough technology for us." Further, still from Oracle, "The new systems use "critical thread API", or the ability of the Solaris operating system to recognize critical threads in applications and assign them, by themselves, to a single processor core. This allows the critical threads to run at the very highest performance levels without competing with other less critical threads. This delivers faster overall performance by accelerating the more critical components in threaded applications."

Oracle VM Server for SPARC 2.1 [24248]
Adds Live Migration, Improved P2V Tool, Dynamic Resource Management (DRM) between domains
Oracle has augmented its virtualization portfolio with the release of Oracle VM Server for SPARC 2.1, which comes installed on Oracles SPARC T-series servers. Oracle VM Server for SPARC allows up to 128 virtual machines, or "domains", on one system, providing organizations increased flexibility and improved server utilization.
Oracle VM Server for SPARC 2.1 also delivers live migration capabilities to the SPARC T-series server family, including SPARC T3, UltraSPARC T2 Plus and UltraSPARC T2 based servers, allowing customers to quickly and easily migrate running domains from one physical server to another, eliminating application outages and server downtime.
In addition, Oracle Enterprise Manager Ops Center Virtualization Management Pack provides full lifecycle management of Oracle VM Server for SPARC.
