whitepaper Market Risk and Algorithmic Trading2006-10-24 Advanced Micro Devices (AMD)
  In the evolving financial markets, ever-more complex quantitative analyses are performed. Some constantly assess the market risk of portfolio exposures, while others calculate the probability of reward for various strategies in the continually shifting markets. Increasingly, algorithmic trading programs automatically execute the trade orders that result. With the growing adoption of the AMD Opteron processor, high performance computing for quantitative modeling and algorithmic trading in the financial markets likely will increase. Simulation modeling techniques quantify market risk, measuring the probability and magnitude of potential loss due to change in prices. As market liquidity decreases, typically price volatility and, hence, market risk increases. With the recent introduction of decimalization, the U.S. equity market structure dramatically changed.

whitepaper High Performance Computing: Compatible Acceleration Using Fine Grain, Parallel Processing2006-10-24 CPU Technology
  In many cases, organizations are not realizing expected performance increases when running large, complex applications on High Performance Computing (HPC) computers. A mismatch between existing computer architectures and the applications running on them is exacerbating the inefficiencies inherent in these systems. Tailoring a computer to meet the specific resource requirements of a group of applications can yield an optimal machine without the massive expense in time and dollars of changing the architecture and rewriting the software. Multi-processor in Memory (MNM) technology, combined with CPU Tech's System-on-a-Chip (SoC) integration, can produce high throughput compatible processing at very low power and cost.

whitepaper An Advanced Cache Power Model for an Embedded Processor Using SLEEP Methodology2006-10-06 Koninklijke Philips Electronics
  Low power design of the digital SoC (System on a Chip) is a hot research area recently. The power estimation techniques can be implemented at all abstraction levels in the low power design flow, of which system level is on the top. The power estimation in this level can greatly save the designer's effort and time of going to the lower design levels. However, in system level, the detailed information about the circuit of the system cannot be extracted.   
whitepaper Securing Your Future With HP: Moving Forward With OpenVMS2006-10-01 Hewlett-Packard (HP)
  HP announced plans to port OpenVMS, its layered software products and compilers, to the Integrity server architecture and to ensure a smooth transition from OpenVMS on AlphaServer to OpenVMS on Integrity server. This paper assures that a person can continue to use the AlphaServer running OpenVMS well into the future, to help himself understand what he needs to do to transition to Integrity servers when the business needs require a transition, and to identify the resources available to help to do so.

whitepaper An Enterprise Database Performance Comparison of the Dell PowerEdge 6850 and the Sun Fire V490 UltraSPARC Server2006-10-01 Dell
  Computer processor vendors continue to bring out higher performing processors. The latest generation from vendors such as Intel and Sun feature two processor cores and a large L3 cache on the processor module. To test the performance of latest generation dual core quad socket servers from Dell and Sun, a performance test using the open source and freely available Dell DVD store database was conducted. Similarly configured Dell PowerEdge 6850 and Sun Fire V490 server were used for the performance comparison. The large (100 GB) version of the DVD store database was built with a leading enterprise database server and was configured with similar settings on both systems.

whitepaper Quad-Core and Dual-Core Intel Xeon Processor-Based Two-Processor Workstations: Superior Performance to Improve How People Work and Create Every Day2006-10-01 Intel
  With more complex designs and an overwhelming desire to push the envelope of business, creative, and scientific possibilities, the challenges get tougher every year. Yet, these are what drives one at Intel to take the next leap in technologies so they can reach their objectives. With Intel technologies built into one's work environment, one can build success into the business. Intel continues to build more capabilities into platforms so the user can do much more with a lot less. For over 30 years, Intel has helped developers and businesses solve their toughest problems with advanced computing capabilities and technologies - from the first multi-purpose processor in 1974 to the industry's first quad-core, 64-bit processor-based platforms today.

whitepaper Hardware Support for Spin Management in Overcommitted Virtual Machines2006-09-20 Association for Computing Machinery
  Multiprocessor Operating Systems (OSs) pose several unique and conflicting challenges to System Virtual Machines (System VMs). For example, most existing system VMs resort to gang scheduling a guest OS's virtual processors (VCPUs) to avoid OS synchronization overhead. However, gang scheduling is infeasible for some application domains, and is inflexible in other domains. In an overcommitted environment, an individual guest OS has more VCPUs than available physical processors (PCPUs), precluding the use of gang scheduling. In such an environment, the authors demonstrate a more than two-fold in-crease in runtime when transparently virtualizing a chip-multiprocessor's cores.

whitepaper Phoenix: Detecting and Recovering From Permanent Processor Design Bugs With Programmable Hardware2006-09-18 University of Illinois
  Although processor design verification consumes ever-increasing resources, many design defects still slip into production silicon. In a few cases, such bugs have caused expensive chip recalls. To truly improve productivity, hardware bugs should be handled like system software ones, with vendors periodically releasing patches to fix hardware in the field. Based on an analysis of serious design defects in current AMD, Intel, IBM, and Motorola processors, this paper proposes and evaluates Phoenix - novel field-programmable on-chip hardware that detects and recovers from design defects. Phoenix taps key logic signals and, based on downloaded defect signatures, combines the signals into conditions that flag defects.   
whitepaper Evaluation of ESX Server Under CPU Intensive Workloads2006-09-06 Brigham Young University
  Virtual machines are used by IT departments to provide better hardware utilization and to isolate users and programs from each other. The paper explores how configuration changes affect the throughput of virtual machines hosted on ESX Server during CPU intensive workloads. In particular the paper explores how Hyper-Threading, Virtual SMP, and the amount of RAM allocated affect throughput. Hyper-Threading is Intel's implementation of simultaneous multithreading technology and was introduced with the Xeon processor. Virtual SMP allows ESX Server to host virtual machines with two virtual processors.

whitepaper Intel Energy-Efficient Performance: Performance Made Energy Efficient Through New Technological Leaps2006-12-27 01:00:55 Intel
  The drive for more performance is relentless, but is now matched with a need for greater energy efficiency-performance made energy efficient. Intel is addressing this need by delivering unprecedented innovations in processor architecture, silicon, platform technologies, and software. These innovations are delivering superior performance in the most efficient ways to give people what they care about most - whether it's smaller devices, increased performance, lower cooling bills, or better energy-efficiency.
