Intel Webinar and OpenCL

Intel Webinar and OpenCL

 

One of the greatest strengths of OpenCL as a heterogeneous programming tool is its capability to target multiple devices. While it’s normal to associate OpenCL, CUDA and massive parallel processing with GPUs, there are tasks which have coarser parallelism and can be better handled by CPUs.

In this upcoming Intel webinar they promise to demonstrate how to use the computing power of Intel hardware using OpenCL. This could be very useful if they discuss which types of algorithms are best suited for OpenCL targeting GPUs, OpenCL targeting CPUs and multithreading for CPUs with work stealing (like Microsoft’s Parallel.For or Intel’s own Silk developed at MIT).

OpenCL Kinect Pottery

Virtual Pottery using Kinect and OpenCL/GL interop

 

The video below is a preview of CMSoft research in OpenCL OpenGL interoperation to create interactive virtual environments using Kinect.

In this demonstration, we create interactive deformation of a virtual mud body. Stay tuned for the upcoming tutorial on Using C# and OpenCL / GL Interop to Manipulate Kinect Data!

 

 

OpenCLCodeChecker updated

OpenCLCodeChecker updated

 

Our OpenCLCodeChecker editor is designed to allow developers to compile their OpenCL C99 code without having to compile the entire code, for convenience. It has been updated to incorporate some useful features:

– Added status bar to show line and column number
– Select all with Ctrl+A
– Fixed some _native and _half function typos

 

Download OpenCLTemplate and the updated OpenCLCodeChecker.

 

OpenCL for FPGAs

OpenCL for FPGAs

 

Altera announced early access to their FPGA program. At this point, however, it seems to be limited to a very specific group through courses. We hope the framework is made publicly available soon and that it enables the construction of embedded FPGA systems using OpenCL as the programming language. In any event, we at CMSoft hope this initiative will motivate many other hardware manufacturers to adopt OpenCL as mainstream language for parallel processing.

OpenCL at SIGGRAPH 2012

OpenCL meeting at SIGGRAPH 2012

 

SIGGRAPH 2012 is approaching and, for the second year, we’ll be there to exchange ideas about parallel computing and OpenCL, as well as check up on the latest technologies which will be presented in the most important conference of computer graphics. Khronos Group has Birds of a Feather events which are the perfect meeting spot for OpenCL programmers and adopters.

We look forward to meeting everyone interested in exchanging ideas about parallel processing, technology or just to chat about life =]; feel free to send me an email.

See y’all on Wednesday August 8th.

Case study: heat transfer simulation using OpenCL OpenGL interop

 

Heat transfer and, more generally, parabolic partial differential equations are a very important class of problems in physics and mathematics. Analytic solutions aren’t available for real-world problems where initial and boundary conditions can be arbitrary.

CMSoft presents video tutorials and source code with detailed information about how to create the CLGL shared context, use OpenCL to accelerate the simulation of heat transfer and share an OpenGL texture to present the results to the user.

This is an example of the video tutorials to come should our user community show interest (in our poll, left menu) to watch a complete series of video tutorials. Otherwise we’ll concentrate our efforts and time on striving to create high-quality code content with online text explanation.

OpenCL video tutorial

CMSoft poll: video tutorials about OpenCL using C#

Would you like us at CMSoft to create a series of video tutorials about how to develop OpenCL applications using C#? Vote using the poll in the left menu.

Video lectures and tutorials have become a major source of technical information. From MIT OpenCourseWare to Khan Academy, high quality education is being offered for free and made available to people all over the world.

We at CMSoft are considering the idea of creating a step-by-step video tutorial covering the aspects discussed in our OpenCL in C# tutorial using Cloo and OpenCLTemplate and beyond.

Our idea is to record some videos showing the very first basics of the OpenCL memory model and data-parallel structure and from there move to on-demand topics such as image processing, __local memory usage, OpenCL/OpenGL interop or how to use OpenCL using multiple GPUs and CPUs. We might even cover C++ or advanced synchronization sometime.
