Hi,
Version 2.1.1b of GPGPU-Sim has been uploaded. This version of GPGPU-
Sim includes several enhancements versus 2.1.0b including support for
OpenCL.
Perhaps you can reuse wrapper code..

Hi,
I would like to use ocelot to create an openCL execution/emulation environment.
Has there been any progress on this issue? If not, I will be willing to help create the openCL front end.

Unfortunately, I starting this but was unable to make much useful progress. My studies moved elsewhere and I forgot I was assigned this task. Anyone is free to pick up the slack.

Not a problem. We've looked into this in detail and concluded that the amount of effort required would be greater than 1-2 people full time for a year. In the meantime, OpenCL has become less interesting from our end as all of the functionality exists in CUDA, and at this point, CUDA applications seem to still dominate the market.

I'm going to leave this open in case anyone else is interested in picking it up.

Has anyone still work on adding an OpenCL frontend? I think it will be very useful since current OpenCL compilers are verdor specific, there is not an OpenCL compiler which can generate optimized code for NV GPU, AMD GPU and x86 CPU.
OpenCL is the future!

There is not currently anyone working on this. We would love volunteers to take this up, particularly someone with experience developing compiler language frontends. At this point though, it is a large engineering effort, and most of the contributors to Ocelot are PhD students who want to leverage the codebase for their research. CUDA serves that purpose well enough in most cases, and the lack of language features like templates and C++ support in OpenCL make it unlikely that any of the current Ocelot developers are going to spend time on this.

Eventually I would like to move Ocelot towards a complete open source compiler for parallel processors (GPUs). Specifically by moving beyond PTX to a new IR and adding in a language front-end and a generic framework for supporting additional backends. We need people to step up and take ownership of these components though.

OpenCL frontend is coming! The ability of Clang/LLVM to parse OpenCL/C and generate PTX via the NVPTX code generator makes this more realistic. I am a research scientist working for Prof. Hyesoon Kim at Georgia Tech on an OpenCL variant called LCL ("Light" CL) for mobile and embedded platforms (sponsored by Samsung). Implementing basic OpenCL functionality via Ocelot is a stepping-stone for us towards LCL. We have a subset of the Platform and Runtime APIs working and are making efforts to extend the library of built-ins required by OpenCL/C available at LLVM.org which was initiated by Peter Colingbourne.

Any progress on this? It would be a way to implement OpenCL 1.2 and 2.0 functionality on supporting NVidia hardware without waiting for NVidia to finally update its drivers.
