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 Rapid Context Switching on an FPGA Custom Processor With a Configurable Number of Registers2006-10-16 National Technical University of Athens
  This paper presents the xr16rcs, a custom processor for embedded system applications that is an extension of the xr16 RISC CPU. Both the xr16 and xr16rsc have been implemented on a Field Programmable Gate Array (FPGA) chip. The innovation of this work lies in the design of a context switching mechanism that is implemented with a configurable number of CPU register sets. The number of application tasks is determined at compilation time and the resulting source code for programming the FPGA chip is produced automatically. For an application of n tasks, n register sets are produced, individually assigned to a specific task.

whitepaper It Takes Advanced Manufacturing Technology to Make a Native Multi-Core Processor2006-10-09 Advanced Micro Devices (AMD)
  This white paper shares some of the approaches that position AMD among the leaders in the industry. The paper explores how its patented APM (Automated Precision Manufacturing) technologies enhance the speed, accuracy, and agility of production facilities (known in the industry as "Fabs"). Then it examines how AMD stays at the forefront of semiconductor technology development by leveraging its intellectual and financial resources through collaboration with other industry leaders. Next, the paper discusses how AMD introduces new technology into its fabs using evolutionary, rather than revolutionary tactics, and how it refines that technology using a unique "Lab in fab" approach.

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 eMIPS, a Dynamically Extensible Processor2006-10-01 Microsoft
  The eMIPS architecture can realize the performance benefits of application-specific hardware optimizations in a general-purpose, multi-user system environment using dynamically extensible processor architecture. It allows multiple secure Extensions to load dynamically and to plug into the stages of a pipelined data path, thereby extending the core instruction set of the microprocessor. Extensions can also be used to realize on-chip peripherals and if area permits even multiple cores. The new functionality can be exploited by patching the binaries of the existing applications, without requiring any changes to the compilers.

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.
