whitepaper zAAPs and zIIPs: Increasing the Strategic Value of System z2007-01-09 IBM
  With the addition of IBM System z application assist processors (zAAPs) and integrated information processors (zIIPs) to the portfolio of special-purpose IBM System z processors, the reinvention of the IBM mainframe continues. Jointly, zAAPs and zIIPs provide significant IBM System z9 integrated and cost-effective processing cycles for nowadays strategic Java and DB2t for z/OS programming platforms which are increasingly fundamental to enterprise-class business environments. Overviews of zAAPs and zIIPs are presented that describe their functionality, design, and use by the z/OS operating system to achieve the execution of both Java and z/OS DB2 programming functions.   
whitepaper The Future Data Center - Part 1: Multi-Core Processors2007-01-08 Symantec
  Multi-core microprocessors promise substantially improved system performance with commensurately reduced power and cooling requirements. However, multiprocessor programming can prove a daunting activity and involve a learning curve. Some applications inherently cannot exploit multiprocessing facilities and many applications are extremely difficult to partition into parallel processing architectures. Small wonder that attempts to parallelize existing applications have sometimes been referred to as paralyzing the applications.

whitepaper System x3755 Technical Introduction2007-01-03 IBM
  Delivering an industry-leading, 64-bit framework for high performance computing and business computing, the IBM System x3755 is built for speed. The x3755 eliminates system architecture bottlenecks through the use of separate, high-speed links between the processors, main memory, and I/O. The AMD Direct Connect Architecture and HyperTransport technology combined with IBM Xcelerated Memory Technology drive the x3755 to deliver the performance, availability, and manageability needed for the next generation of high performance computing servers that require low latency and high speed access to memory. This paper describes the technical aspects of the server.

whitepaper Enabling BSS Business Process and System Convergence With HP Integrity, HP-UX and HP BladeSystem2007-01-01 Hewlett-Packard (HP)
  Communications Service Providers are faced with the convergence of voice, data and information technology infrastructure, ongoing mergers and acquisitions, and the constant evolution of services. Intel Itanium 2 processor-based HP Integrity platforms running HP-UX - from 1U rack optimized systems to cabinet-sized symmetric multi-processor systems and now high-performance, high density blade form-factor systems - offer an exciting opportunity to accelerate next-generation BSS infrastructure at an excellent price/performance ratio.

whitepaper High-Speed Interconnect and Packaging Design of the IBM System z9 Processor Cage2007-01-01 IBM
  This paper describes the system packaging and technologies of the IBM System z9 enterprise-class server. The central electronic complex of the system consists of four nodes, each housing a MultiChip Module (MCM) with 16 chips consuming up to 1,200 W. The z9 server doubles the multiprocessor performance of the System z990 by increasing the Central Processing Unit (CPU) configuration and using an internally developed elastic interface to increase interconnect speed on all high-speed buses. High frequencies and massively parallel connectivity lead to a raw packaging bandwidth of up to 1,764 GB/s between processors and cache within a single frame for a fully configured four-node z9 system.

whitepaper Power Comparison of Dell PowerEdge 2950 Using Intel X5355 and E5345 Quad Core Xeon Processors2007-01-01 Dell
  This paper will compare the performance of the PowerEdge 2950 using two different quad-core Intel Xeon processors that consume different amounts of power. Results will show that the Intel Xeon E5300 family of processors can approach the performance of the X5300 series of processors while realizing a power savings of approximately 15%.   
whitepaper An FPGA-Based Network Processor for IP Packet Compression2007-01-01 University of Calgary
  This paper describes the design, implementation, and experimental evaluation of a reconfigurable network processor that can do on-the-fly content adaptation of IP packets for wired or wireless networks. In the demonstration application, FPGA technology is used in conjunction with traditional RISC micro-processors to perform IP packet compression in hard-ware, using a CAM-based hardware implementation of the Lempel-Ziv (LZ) compression algorithm. The experimental evaluation considers HTTP Web browsing traffic using the TCP/IP protocols. The measurement results show that the proposed LZ compression architecture can reduce network byte traffic volume by 5- 38%. Furthermore, the hardware-based approach pro-vides consistent throughput performance as the compression buffer size is increased.

whitepaper A Novel Architecture for VLIW Processor2007-01-01 Anna University
  Technology has seen the development of processor industry right from micro to the latest Nanotechnology with speed being important criteria. Not much attention has been given to the power required to drive these Integrated Circuits. With gaining popularity in mobile computing, developing mobile processors have gained popularity since these processors possess unique properties like low power consumption and dissipation. This paper aims at designing a low power Very Long Instruction Word (VLIW) processor with built in FFT processor, which uses single clock frequency. This VLIW processor is designed with two modules one for VLIW processor and the other one is Hybrid dynamic voltage scaling module.

whitepaper High Fidelity Simulation of Mobile Cellular Systems With Integrated Resource Allocation and Adaptive Antennas2006-12-29 Stanford University
  Using parallel processing, the execution time of wireless network simulations can be significantly decreased without compromising the fidelity of the simulation. However, incorporating details such as signal propagation, interference, and resource allocation schemes may add considerable complexity to the parallel simulation which may overshadow the gain of parallelization. This paper reports on a recent work on parallelizing a high fidelity mobile wireless network simulator where dynamic resource allocation schemes are incorporated and the physical layer characteristics are included in sufficient detail.
