whitepaper Breaking the Chains - Using LinuxBIOS to Liberate Embedded x86 Processors2007-06-30 Advanced Micro Devices (AMD)
  While x86 processors are an attractive option for embedded designs, many embedded developers avoid them because x86-based systems remain dependent on a legacy BIOS ROM to set up the system. LinuxBIOS is an open source solution that replaces the proprietary BIOS ROMs with a light-weight loader. LinuxBIOS frees the developer from complex CPU and chipset initialization and allows a variety of payloads to be loaded, including the Linux kernel itself. This paper reviews the journey of the AMD Geode processors and chipset as they were integrated into LinuxBIOS to become the centerpoint of the One Laptop Per Child (OLPC) project. The paper also discusses how embedded developers can take advantage of the LinuxBIOS environment for their own x86-based projects.

whitepaper Virtual Hierarchies to Support Server Consolidation2007-06-13 Association for Computing Machinery
  Server consolidation is becoming an increasingly popular technique to manage and utilize systems. This paper develops CMP memory systems for server consolidation where most sharing occurs within Virtual Machines (VMs). The memory systems maximize shared memory accesses serviced within a VM, minimize interference among separate VMs, facilitate dynamic reassignment of VMs to processors and memory, and support content-based page sharing among VMs. The paper begins with a tiled architecture where each of 64 tiles contains a processor, private L1 caches, and an L2 bank. It reveals why single-level directory designs fail to meet workload consolidation goals. It develops the paper's central idea of imposing a two-level virtual (or logical) coherence hierarchy on a physically flat CMP that harmonizes with VM assignment.

whitepaper The University of Utah Supports Cutting-Edge Research by Delivering 50 Percent More Work With Half the Power Consumption2007-06-01 Dell
  University of Utah's Center for High Performance Computing (CHPC) supports the high-performance computing needs of research projects university-wide. The CHPC's aging high-performance computing cluster needed an upgrade; increasing demand for scientific research required a powerful cluster within the university's budget. The CHPC deployed a new high-performance computing cluster based on Dell Power-Edge servers with two dual-core AMD processors running Red Hat Enterprise Linux operating system and multiple scientific computing applications.

whitepaper Dell Latitude Notebooks With Embedded Broadband Wireless Networking Provide Sales Force With Mobile Access2007-06-01 Dell
  Edward Don & Company is a world-class distributor of food service equipment. Edward Don realized that it needed a mobile sales force that could access e-mail, inventory tracking, and order processing systems in the field. They wanted their sales reps to be able to show customer's products on their notebook computer screens, check inventory, create a quote, e-mail it to the customer on the spot, and walk out of there with a signed purchase order. Edward Don chose to equip its salespeople and staff with nearly 400 Dell Latitude D620 notebook computers with Intel Core Duo processors running the Microsoft Windows XP operating system, as well as the full Microsoft Office suite.

whitepaper AMD64 Multi-Core Computing Platforms and SolidDB Enable Consolidated Approach to Subscriber Databases and Related Applications2007-05-30 Advanced Micro Devices (AMD)
  With solidDB and AMD64 Multi-Core Processors, system architects can consider a new, consolidated approach to subscriber databases and related applications. In this new approach, the applications are run in the same multi-core/multi-processor system, together with the database server. With the consolidated approach, benefits can include greater performance, higher processor utilization, and improved load balancing and lower administration costs. In the consolidated approach, applications communicate with the dataset via the high bandwidth and low-latency Direct Connect Architecture, to decrease external network traffic and improve efficiency. AMD Virtualization technology may further improve performance when virtualization is used to place applications and database in different virtual machines.

whitepaper Do Newer Processors Equate to Slower Applications?2007-05-16 Jupitermedia
  Processor speeds have hit the wall with current technologies. The speed is nearly at the maximum that can be obtained, and people are virtually at the ceiling with current technology. Some additional speed will be tweaked and added, but overall it seems that using current processor technology, the maximum speed of a processor is just about upon users.

whitepaper Tuning C++ Applications for the Latest Generation X64 Processors With PGI Compilers and Tools2007-05-09 Advanced Micro Devices (AMD)
  At CUG 2006, a cache oblivious implementation of a two dimensional Lagrangian hydrodynamics model of a single ideal gas material was presented. This paper presents further optimizations to this C++ application to allow packed, consecutive-element storage of vectors, some restructuring of loops containing neighborhood operations, and adding type qualifiers to some C++ pointer declarations to improve performance. In addition to restructuring of the application, analysis of the compiler-generated code resulted in improvements to the latest PGI C++ compiler in the area of loop-carried redundancy elimination, resolution of pointer aliasing conflicts, and vectorization of loops containing min and max reductions. These restructuring and compiler optimization efforts by PGI and Sandia have resulted in application speedups of 1.25 to 1.80 on the latest generation of x64 processors.
