19 Mar 2012 How Memory Allocation Affects Performance in Multithreaded Programs [25732]
Sniffing Out Lock Contention with Several Tools

If your new server has an alarmingly lower transaction rate than you had anticipated, Rickey C. Weisner suggests that you look first at lock contention in the memory allocator. His article demonstrates the use of prstat to determine whether there is lock contention. Demonstrated as well is the use of Professor Emery Berger's MT-hot allocator named Hoard, and of the mtmalloc (both old and new), and the libumem memory allocators. The question of which is best is answered by Weisner's use of a test harness, which appears to give the edge to the new mtmalloc.

24 Oct 2011 Oracle's SPARC T4 Prices Mask Improved Value [24799]
Prickett Morgan Hauls Out His Magnifying Glass

Writing for The Register, Timothy Prickett Morgan provides a rather undramatic assessment of Oracle's new SPARC T4 Processors which, he claims "offer slightly better performance [than the T3] on jobs that like threads (like database processing or Java serving), so for the same or a little less money, you get beefier memory and disk configurations." This, Morgan asserts, amounts to a fudge factor in that it is workloads that like threads on which the performance of the SPARC T4 is most dramatic.

11 May 2011 SPARC T-3, Enterprise M-Series Servers Demonstrate Outstanding Performance [24172]
Several Benchmark Results Showcase SPARC Performance Superiority Across Oracle’s Software Portfolio

Several recent benchmark results demonstrate the viability of Oracle's integrated approach to hardware and software design, making it clear that Oracle solutions run optimally on Sun Oracle hardware. Oracle tested its SPARC T-Series and SPARC Enterprise M-Series servers in performance measures against IBM notably and in one instance delivered results nearly 2.5 times the IBM entry. Among the benchmarks involved were TPC-H@3000GB; JD Edwards EnterpriseOne "Day-in-the-Life" benchmark; and Oracle Communications ASAP. Oracle announced results as well for benchmarking tests using the Avitek medical Records application and on cryptographic performance of the SPARC T3 processor running the IPsec AES-256-CCM cipher. In every instance, Oracle's current line of servers outperformed either the competition or earlier versions of hardware.

29 Mar 2011 SPARC T3-1B Doubles Performance on Oracle Fusion Middleware [24047]
WebLogic Avitek Medical Records Sample Application

Running a sample application of the Avitek Medical Records and Oracle WebLogic Server 11g software, a configuration using Oracle SPARC T3-1B and SPARC Enterprise M5000 servers, the latter running the Oracle database, showed excellent scaling of different configurations. The configuration had 2.1x times the transactional throughput over the previous generation UltraSPARC T2 processor based Sun Blade T6320 server module. The SPARC T3-1B server shows linear scaling as the number of cores in the SPARC T3 processor used in the SPARC T3-1B system module are doubled, writes Brian Whitney in a BestPerf blog. He notes that the Avitek Medical Records application instances were deployed in Oracle Solaris zones on the SPARC T3-1B server, allowing for flexible, scalable and lightweight architecture of the application tier.

11 Mar 2011 Oracle's SPARC T3-1, SPARC T3-2, SPARC T3-4 and SPARC T3-1B Server Architecture [23999]
Higher Levels of Performance in as Little as 2RU

The 45-page white paper "Oracle's SPARC T3-1, SPARC T3-2, SPARC T3-4 and SPARC T3-1B Server Architecture" explains how these servers, which take the industry's first massively threaded system-on-a-chip (SoC) to new performance levels, can deliver the breakthrough performance and energy efficiency needed to drive data center infrastructure and address typically demanding data center challenges such as guaranteeing availability even while scalability measures are underway. With 128 threads per processor, on-chip memory management, two 10 GbE interfaces, PCIe, and on-chip cryptographic acceleration, the SPARC T3 processor fundamentally redefines the capabilities of a modern processor, the white paper maintains. By incorporating cache coherency for multiprocessor support, SPARC T3 processors allow these capabilities to be multiplied incrementally. With these servers, customers can enjoy fourth-generation multicore, multithreading technology that supports up to 128 threads in as little as two rack units (2RU), and provides increased computational density while staying within variously constrained envelopes of power and cooling.
