In the context of the CERN openlab collaboration, Tim Mattson (Intel) comes to CERN for two days on 16 and 17 June 2011. A workshop is organised the first day and a computing colloquium the second one.

The workshop proposes to give the participants an introduction to OpenCL.

Description:

OpenCL is a standard for programming heterogeneous computers built from CPUs, GPUs and other processors. It includes a framework to define the platform in terms of a host (e.g. a CPU) and one or more compute devices (e.g. a GPU) plus a C-based programming language for writing programs for the compute devices. Using OpenCL, a programmer can write task-based and data-parallel programs that use all the resources of the heterogeneous computer. In this tutorial, we will introduce OpenCL. This will be a “programmer’s introduction” where we cover the ideas behind OpenCL but also show how these ideas are translated into source code. We will do this through a series of progressively more challenging examples, thereby providing a set of pedagogically useful examples that experienced HPC programmers can use to quickly become productive OpenCL programmers.

In the afternoon there will be an hands-on tutorial. Please, bring your own laptop. We will provide access to some machines with Intel OpenCL Linux installed, but it would be best if you had OpenCL installed on your own laptop. We will drive the tutorial around the Windows release from Intel, but we invite to use Linux version.

You can download the beta release of OpenCL (Linux and Windows) from Intel at:         http://software.intel.com/en-us/articles/opencl-sdk/

For Apple laptops, OpenCL is included with Xcode for Mac OS X (Snow Leopard release and beyond). You can also use the AMD release of OpenCL for x86 processors which can be downloaded at:

About the speaker:

Tim Mattson is a parallel programmer (Ph.D. Chemistry, UCSC, 1985). The recurring theme of his career is to do whatever it takes to meet the needs of parallel application programmers.

Tim has been with Intel since 1993 where he has worked with brilliant people on great projects including:

• the first TFLOP computer (ASCI Red),

• the OpenMP API for shared memory programming,

• the OpenCL programming language for heterogeneous platforms,

• programming Intel's first TFLOP chip (the 80 core research chip), and

• Intel’s 48 core, SCC research processor

Tim has published extensively including the books Patterns for Parallel Programming (with Beverly Sanders and Berna Massingill, Addison Wesley, 2004) and An Introduction to Concurrency in Programming Languages (with Matthew J. Sottile and Craig E Rasmussen, CRC Press, 2009), and the OpenCL Programming Guide (with Aaftab Munshi, Ben Gaster, James Fung, and Dan Ginsburg, Addison Wesley, summer 2011).
