Planning Considerations for HiperDispatch Mode 2008-04-02 IBM

For all levels of z/OS, a TCB or SRB may be dispatched on any logical processor of the type required (standard, zAAP or zIIP). A unit of work starts on one logical processor and subsequently may be dispatched on any other logical processor. The logical processors for one LPAR image receive an equal share for equal access to the physical processors under PR/SM LPAR control. For example, if the weight of a logical partition with four logical processors results in a share of two physical processors, or 200%, the LPAR hypervisor will manage each of the four logical processors with a 50% share of a physical processor. All logical processors are used if there is work available, and they typically have similar processing utilizations.

Live Migration With AMD-V Extended Migration Technology 2007-12-17 Advanced Micro Devices (AMD)

Virtual Machine migration is a capability being increasingly utilized in today's enterprise environments. With live migration, a Virtual Machine Monitor (VMM) moves a running Virtual Machine (VM) nearly instantaneously from one server to another for a seamless experience to the end user while maintaining guest uptime. However, if the processors running in the computers in the pre and post migration environment are not identical, live migration can result in unexpected behavior of the guest software. Since the introduction of its AMD64 processor technology in 2003, AMD has worked closely with virtualization software developers to define the functionality necessary to ensure that live migration is possible across a broad range of AMD64 processors.

Tuning Symantec Brightmail AntiSpam on UltraSPARC T1 and T2 Processor-Powered Servers 2007-12-07 Sun Microsystems

Electronic mail is a business-critical function in virtually every enterprise, and it is also one that is under constant attack. Well-known viruses such as Melissa, and worms like SoBig have propagated through email and have disrupted user PCs and corporate networks worldwide. Fraudulent email messages find their ways into inboxes and tempt unsuspecting users into divulging personal information at phishing sites. As companies recognize that their intellectual property can easily leave their premises through email messages, filtering outbound and internal messages is becoming as important as protecting an organization from incoming traffic.

Cache Optimization for Coarse Grain Task Parallel Processing Using Inter-Array Padding 2007-12-01 Waseda University

The wide use of multiprocessor system has been making automatic parallelizing compilers more important. To improve the performance of multiprocessor system more by compiler, multigrain parallelization is important. In multigrain parallelization, coarse grain task parallelism among loops and subroutines and near fine grain parallelism among statements is used in addition to the traditional loop parallelism. In addition, locality optimization to use cache effectively is also important for the performance improvement. This paper describes inter-array padding to minimize cache conflict misses among macro-tasks with data localization scheme which decomposes loops sharing the same arrays to fit cache size and executes the decomposed loops consecutively on the same processor.

Parallel Processing Using Data Localization for MPEG2 Encoding on OSCAR Chip Multiprocessor 2007-12-01 Waseda University

Need for efficient processing of multimedia applications on PCs, mobile phones, games and so on have been increasing. Especially, low cost, low power consumption and high performance processors for multi-media applications have been expected. To satisfy the demands, chip multiprocessor architectures which allow giving scalability using multigrain parallelism are attracting much attention. However, to get performance of chip multiprocessor architectures, data locality optimization for target applications is also required. This paper describes a parallel processing scheme for MPEG2 encoding using data localization technique which improves execution efficiency by using global data locality optimization among different loops with coarse grain task parallel processing, and evaluates the performance of the proposal scheme on OSCAR chip multiprocessor architecture.

Genesys Enterprise Routing Solution V7.5 on IBM System p 570: Performance Report V1.0 2007-12-01 IBM

An IBM System p 570 with an IBM POWER6 processor server running IBM AIX 5L Version 5.3.6 and IBM DB2 Universal Database Version 8.2.7 set an outstanding record on the Genesys Inbound Voice Solution v7.5 for the Inbound Call Center industry in September 2007. A 16-way IBM System p6 570 4.7 GHz IBM,9117-MMA server, configured as four Logical PARtitions (LPARs) using a total of 16 CPUs, demonstrated the scaling capabilities across three diverse configurations to meet the demands of an enterprise-level of Genesys' Inbound Voice solution and Reporting implementation. Just one LPAR has the capability of handling a Call Center with call activity of up to 80 calls per sec.

Performance Characterization of HP ProLiant DL360 G5 With Quad-Core Intel Xeon Processors (3.16 GHz/2x6 MB) in a 64-Bit HP Server Based Computing Environment 2007-11-01 Hewlett-Packard (HP)

This paper describes a performance characterization performed utilizing the HP 64-bit test harness, which incorporates a Microsoft Office 2003 workload. Test results cannot be compared directly with the results of tests performed using the 32-bit Office XP- or Office 2003-based harnesses. Combining concentrated 1U computing power, HP Integrated Lights-Out 2 (iLO 2) management, and essential fault tolerance, the HP ProLiant DL360 G5 server is a great choice for any business where space is at a premium.

Virtual Software Demos Reduce Sales Expense and Shorten Sales Cycles 2007-11-01 Microsoft

Makers of complex software programs run into challenges when trying to demonstrate their products. They either have to fly prospective customers to demonstration centers, or salespeople have to configure custom demos and carry around expensive computers to run them. VLabSource, of Redmond, Washington, offers a Web-based demonstration management system called DemoPoint that salespeople can use to demonstrate their wares with nothing more than a browser and a broadband Internet connection. VLabSource uses Microsoft Virtual Server 2005 R2 to create virtual machines, which run on Dell PowerEdge server computers powered by dual-core Intel Xeon processors.
