Cloud-based Services and Applications Chairs: Prof Mark Baker, University of Reading Dr. Marcel Kunze, Forschungszentrum, Karlsruhe Abstract Cloud computing is increasingly being used for what was known as “on-demand” and “utility computing”. The services provided, the APIs and the applications that can be hosted by these Cloud providers have superseded the use of the grid, and are increasingly becoming popular with users. There are obviously two sides to the services that are provided by Cloud providers: those that are supplied by commercial entities, such as Amazon and Google , as well as those that are open-source systems, such as provided by OpenCirrus and Eucalyptus . In this workshop we wish to examine and explore the services, interfaces and types of applications that can be executed on Cloud systems. In addition, we are interested in the interfaces used to access the underlying services, the pros/cons of using virtualisation, the range and scope of applicat...

Presenter Mordechai Butrashvily CEO Company for Advanced Supercomputing Solutions Ltd. Abstract This meeting will showcase NVIDIA library implementing various performance primitives on the GPU for various purposes, from image/video processing to other tasks. The library can be considered as the GPU equivalent of Intel IPP, although with functionality that is added with time. In the meeting we will overview the set of supported functions, test and discuss performance topics with regard to the GPU. Using this library, users can experience between x10 to x50 performance increases when compared to running on the CPU. This meeting will be followed by another, discussing upcoming LAPACK library implementation on the GPU. To reserve your place, please send your contact details to: info@grid.org.il

Prof. Miron Livny The Head of the Condor project: Open Source for High Throughput Computing (HTC) http://www.cs.wisc.edu/condor/ Condor and the Cloud - The Challenges and the Roadmap of Condor The goal of the Condor® Project is to develop, implement, deploy, and evaluate mechanisms and policies that support High Throughput Computing (HTC) on large collections of distributively owned computing resources. Today, Condor is being used as a service in private clouds, Amazon EC2 and is embedded in Redhat Linux. Dhruba Borthakur Software Engineer at Facebook and Project Lead for Apache Hadoop File System Hadoop Distributed File System (including Hive) & Condor I discuss the design and architecture of the Hadoop Distributed File system. I then talk about configuration details about the private Hadoop Cloud used by Facebook to process petabytes of data.

In this post I will show step by step how to install and execute MPI (Message Passing Interface) parallel programs in the .NET environment. A much more detailed tutorial is available here . 1) Installation: My computer is running Windows Vista and Visual Studio 2008 is already installed. Download and install the HPC Pack 2008 (next 5 figures): Then install the MPI.NET SDK.msi (see next 4 figures): 2) Test the installation from the command line (next 3 figures): A "Ping-Pong" program Serial run: As should be, the firewall detects the communication traffic and the user should allow it: Parallel run: 3) MPI "Hello" demo using Visual Studio 2008 and C# (next 5 figures): Start a new console C# project: Add Reference to the MPI component: Build the executable: Execute the parallel program with 8 threads: Verifying the execution of the 8 threads by looking at the Task Manager: That's all for now.
