PC Gamers Win Big
CASE STUDY Intel® Solid-State Drives Performance, Storage and the Customer Experience PC Gamers Win Big Intel® Solid-State Drives (SSDs) deliver the ultimate gaming experience, providing dramatic visual and runtime improvements Intel® Solid-State Drives (SSDs) represent a revolutionary breakthrough, delivering a giant leap in storage performance. Designed to satisfy the most demanding gamers, media creators, and technology enthusiasts, Intel® SSDs bring a high level of performance and reliability to notebook and desktop PC storage. Faster load times and improved graphics performance such as increased detail in textures, higher resolution geometry, smoother animation, and more characters on the screen make for a better gaming experience. Developers are now taking advantage of these features in their new game designs. SCREAMING LOAD TiMES AND SMOOTH GRAPHICS With no moving parts, high reliability, and a longer life span than traditional hard drives, Intel Solid-State Drives (SSDs) dramatically improve the computer gaming experience. Load times are substantially faster. When compared with Western Digital VelociRaptor* 10K hard disk drives (HDDs), gamers experienced up to 78 percent load time improvements using Intel SSDs. Graphics are smooth and uninterrupted, even at the highest graphics settings. To see the performance difference in a head-to- head video comparing the Intel® X25-M SATA SSD with a 10,000 RPM HDD, go to www.intelssdgaming.com. When comparing frame-to-frame coherency with the Western Digital VelociRaptor 10K HDD, the Intel X25-M responds with zero hitching while the WD VelociRaptor shows hitching seven percent of the time. This means gamers experience smoother visual transitions with Intel SSDs. -

GMAI: a GPU Memory Allocation Inspection Tool for Understanding and Exploiting the Internals of GPU Resource Allocation in Critical Systems
The final publication is available at ACM via http://dx.doi.org/ 10.1145/3391896 GMAI: A GPU Memory Allocation Inspection Tool for Understanding and Exploiting the Internals of GPU Resource Allocation in Critical Systems ALEJANDRO J. CALDERÓN, Universitat Politècnica de Catalunya & Ikerlan Technology Research Centre LEONIDAS KOSMIDIS, Barcelona Supercomputing Center (BSC) CARLOS F. NICOLÁS, Ikerlan Technology Research Centre FRANCISCO J. CAZORLA, Barcelona Supercomputing Center (BSC) PEIO ONAINDIA, Ikerlan Technology Research Centre Critical real-time systems require strict resource provisioning in terms of memory and timing. The constant need for higher performance in these systems has led industry to recently include GPUs. However, GPU software ecosystems are by their nature closed source, forcing system engineers to consider them as black boxes, complicating resource provisioning. In this work we reverse engineer the internal operations of the GPU system software to increase the understanding of their observed behaviour and how resources are internally managed. We present our methodology which is incorporated in GMAI (GPU Memory Allocation Inspector), a tool which allows system engineers to accurately determine the exact amount of resources required by their critical systems, avoiding underprovisioning. We first apply our methodology on a wide range of GPU hardware from different vendors showing itsgeneralityin obtaining the properties of the GPU memory allocators. Next, we demonstrate the benefits of such knowledge in resource provisioning of two case studies from the automotive domain, where the actual memory consumption is up to 5.6× more than the memory requested by the application.

Monte Carlo Evaluation of Financial Options Using a GPU a Thesis
Monte Carlo Evaluation of Financial Options using a GPU Claus Jespersen 20093084 A thesis presented for the degree of Master of Science Computer Science Department Aarhus University Denmark 02-02-2015 Supervisor: Gerth Brodal Abstract The financial sector has in the last decades introduced several new fi- nancial instruments. Among these instruments, are the financial options, which for some cases can be difficult if not impossible to evaluate analyti- cally. In those cases the Monte Carlo method can be used for pricing these instruments. The Monte Carlo method is a computationally expensive al- gorithm for pricing options, but is at the same time an embarrassingly parallel algorithm. Modern Graphical Processing Units (GPU) can be used for general purpose parallel-computing, and the Monte Carlo method is an ideal candidate for GPU acceleration. In this thesis, we will evaluate the classical vanilla European option, an arithmetic Asian option, and an Up-and-out barrier option using the Monte Carlo method accelerated on a GPU. We consider two scenarios; a single option evaluation, and a se- quence of a varying amount of option evaluations. We report performance speedups of up to 290x versus a single threaded CPU implementation and up to 53x versus a multi threaded CPU implementation. 1 Contents I Theoretical aspects of Computational Finance 5 1 Computational Finance 5 1.1 Options . .7 1.1.1 Types of options . .7 1.1.2 Exotic options . .9 1.2 Pricing of options . 11 1.2.1 The Black-Scholes Partial Differential Equation . 11 1.2.2 Solving the PDE and pricing vanilla European options . -
