HP, Sun Challenge IBM's Power5 While IBM's micro-partitioning capabilities help Big Blue to catch up, Singer said Sun also has the ability to run UNIX on Xeon and Opteron processors. Key features include a new modular design for the Power5 machines and "micro-partitioning," which was borrowed from the company's mainframe suite and allows 10 virtual servers to run on one processor. Dovas also questioned IBM's operating system compatibility, and wondered if AIX applications would have to be rewritten to take advantage of the new Power5 and AIX 5L 5.3, the latest OS driving the Power5 machines. www.internetnews.com /ent-news/article.php/3381271

CRN Breaking News IBM's New p5 Servers Geared For Channel Server Consolidation Unveiled Tuesday, the eServer p5 servers--based on IBM's new POWER5 multicore processors--feature micro-partitioning, which allows a single POWER5 processor to be divided into 10 LPARs (logical partitions), or virtual servers. Scott Bisbee, brand manager at Champion Solutions, a Boca Rotan, Fla.-based solution provider, said IBM is moving Unix to a mainframe-like environment with micro-partitioning, a key capability in server consolidation. When the new p5 servers ship late next month, they will support the current AIX 5L 5.2 Unix operating system, making them compatible with more than 3,600 applications, Freund said. www.crn.com /sections/breakingnews/dailyarchives.jhtml?articleId=23900629   (823 words)

IBM POWER - Wikipedia, the free encyclopedia Ravi Arimilli, IBM's chief microprocessor designer has said: "The POWER5 chip is more of a midrange design that can drive up to the high end and then down to things like blades." IBM servers built with the POWER5 processor offer virtualization features: logical partitioning and micro partitioning. Improvements in the POWER5 over the POWER4 include: a larger L2 cache, a memory controller on the chip, simultaneous multithreading which appears to the operating system as multiple CPUs, advanced power management, dedicated single-tasking mode, Hypervisor (virtualization technology), and eFuse (hardware re-routing around faults). Up to ten LPARs (logical partitions) can be created for each CPU, the biggest 64-Way system can run 256 independent operating systems. en.wikipedia.org /wiki/IBM_POWER   (823 words)

CoSORT IBM eServer i5 and eServer p5 systems are an advanced line of servers that can run Linux on POWER5 microprocessors while leveraging Micro-Partitioning™, an IBM Virtualization Engine™ technology, to achieve unprecedented computing performance and reduced costs for a wide range of business and scientific applications. CoSORT for IBM eServer is the latest in a series of IRI solutions that demonstrates the company's "ongoing commitment to IBM's Linux and server technology initiatives," according to IRI Business Development VP David Friedland. In this case, IRI compiled CoSORT on an IBM eServer i5 i520 running SLES 9 at IBM's Benchmark Center in Rochester, Minnesota. www.cosort.com /public/news/pr/power5.htm   (823 words)

Introduction to clustering on IBM eServer OpenPower 710 Like other POWER5 processor-based hardware, the OpenPower 710 also supports micro-partitioning and virtual I/O functions, which can be enabled as features when you purchase the server or through the Capacity Upgrade on Demand process. The OpenPower 710 is an ideal solution for high performance clustering with its POWER5 processor-based 64-bit architecture and SMT capabilities. This example shows how fault tolerance is possible using two OpenPower 710 models: one acting as a primary server and the other acting as a backup server. www-128.ibm.com /developerworks/linux/library/l-pow-opcluster/?...   (2087 words)

IT-Analysis.com - Power Storage The platforms even share an enormous amount of micro code and utilise a common operating environment making it possible to deploy the two platforms together to be used as part of a single business continuity solution using common remote mirroring capabilities. Indeed, selected models in the DS8000 range can make use of IBM Logical Partitioning (LPAR) technology, well known in the server space, to allow storage resources to be separated into distinct logical storage systems, each of which may operate completely independently. This is especially so in the area of storage platforms where a relatively small number of vendors dominate, at least in a marketing sense, the market. www.it-analysis.com /article.php?articleid=12342   (727 words)

IBM attacks Unix rivals with Power5 Tech News on ZDNet One of the major new features of the Power5 servers is "micro-partitioning," the ability to run as many as 10 operating systems on each processor. The higher-end Unix models are due by the end of the year, including a 64-processor model, said Ravi Arimilli, chief technology officer of eServer microprocessors and systems development and an IBM fellow. The feature is available today, but only using a relatively slow networked storage system; with the Power5+ systems it will happen "in a matter of a few seconds" using conventional Ethernet networking, Arimilli said. news.zdnet.com /2100-9584_22-5266768.html?tag=nl   (727 words)

IBM Adds Low-end Server to Power5 Line The company's Virtulization Engine software allows each Power5 processor to run 10 virtual servers at once and enables micro-partitioning, which allows clients to run several Unix and Linux servers on one system. The pricing of the server is aggressive considering the technology in the machine, designed to take on boxes from rivals HP ( Quote, Chart) and Sun Microsystems ( Quote, Chart) in the two-way Unix market, which IDC said is a $2 billion market. Available next week in rack form with one or two processors, the p5 510 runs AIX 5L v5.3, the latest version of IBM's operating system. www.internetnews.com /ent-news/article.php/3469691   (727 words)

CoSORT IBM eServer i5 and eServer p5 systems are an advanced line of servers that can run Linux on POWER5 microprocessors while leveraging Micro-Partitioning™, an IBM Virtualization Engine™ technology, to achieve unprecedented computing performance and reduced costs for a wide range of business and scientific applications. CoSORT's sort benchmark of 711MB in 22 seconds on both machines "should be indicative of the new level of price-performance CoSORT users can expect when transforming their operational data into information," Friedland observed. The top CoSORT interface is SortCL™ (for sort control language) -- a high-level data definition and manipulation program for reporting, migrating legacy and COBOL sort operations, and for data warehouse extracts, transforms and loads (ETL). www.cosort.com /public/news/pr/power5.htm   (727 words)

How Power5 enhances IBM?s virtualization capabilities In addition to the micro-partitioning described above, the Power5 servers also have the ability to use virtual I/O. The virtual I/O avoids the requirement on Power4 systems to assign I/O for each LPAR - which was a potential waste of I/O resources on the Power4 systems. Power5 is the latest chip from IBM, which will be available on its servers from the high end to the low end. The use of the Power5 chip and the virtualization capabilities in its hardware are proof that IBM is delivering on its promised strategy. www.networkworld.com /newsletters/nsm/2004/1129nsm2.html?fsrc=rss-ibm   (727 words)

Automatic program parallelization. The crux of automatic parallelization lies in the rigourous data flow analysis of the program and a balanced partitioning of the parallel tasks onto the target architecture. A light-weight threaded micro-kernel is designed in close cooperation with the parallel compiler developers, in order to optimize the overall performance on a tightly coupled multiprocessor. Debugging parallel computer systems is known to be a hard task, because of the limited observability of the architecture, and because of the so-called probe effect: observing the system alters its behavior. www.elis.rug.ac.be /brochure/node46.html   (644 words)

ICPP98 Paper Number 1.11.5S In the light of these results, together with recent findings that plasmodesmata facilitate the cell-to-cell transport of macromolecules including proteins and nucleic acids, we advanced the hypothesis that trafficking of regulatory (information) molecules through plasmodesmata may establish a special supracellular communication network between the companion and mesophyll cells, which operates to regulate carbon partitioning [3]. Analyses of diurnal accumulation of carbohydrates and export rates from source leaves, combined with micro-injection experiments in which plasmodesmal function was determined, established that the TMV-MP has a pleiotropic effect on leaf physiology. Transgenic tobacco plants expressing tobacco mosaic virus (TMV) MP have been used to explore the role of plasmodesmata in terms of the transport of photosynthate. www.bspp.org.uk /icpp98/1.11/5S.html   (481 words)
