confused GPU

Hey guys, been back since about a year.

Why on earth there is no GPU project at this moment? GPU's work so more efficient, faster and stuff. It would be such an improvement when people can use there GPU. It's not like that hard to write a GPU workunit, or is it?

Re: GPU

Hey guy, you missed it. The for GPGPU suitable project ran from Q4-2012 to Q2-2013 which caused it [HCC1] to finish several years earlier, so we very well understand what the impact is.

Got an easy code machine for us to convert the rest of the science applications and still get 'exactly' the same results as produced by the CPU? We'd love to have them.

Re: GPU

DennisM6, please read the multitude of posts in regards to it being up to the scientists to decide if they want to support GPU's and not WCG. Also, it would be wise to do a little more research on the topic because it isn't a simple process and not all science can be ran on the GPU's. Even if the science supports GPU's, the programming is much different and would require someone familiar with either CUDA, CAL, or OpenCL in most cases (and there are a few lesser known ones out there) in order to even get to that point.

Re: GPU

Hello DennisM6,
Apparently it is difficult to write a GPU program. The current Mapping Cancer Markers project is run by the same people who wrote the HCC project - both CPU and GPU versions. Right now there is no GPU project in the pipeline. The HCC project was an image analysis program, as was the HDC (Help Defeat Cancer) project many years earlier. I suspect image analysis is relatively easy to port to a GPU. But we don't have an image analysis project.

WCG is ready to run a GPU project if anybody approaches us with a good GPU project.

Re: GPU

When adding CUDA acceleration to existing applications, the relevant Visual Studio project files must be updated to include CUDA build customizations. For Visual Studio 2010 or 2012, this can be done using one of the following two methods:

1.Open the Visual Studio 2010 or 2012 project, right click on the project name, and select Build Customizations..., then select the CUDA Toolkit version you would like to target.

2.Alternatively, you can configure your project always to build with the most recently installed version of the CUDA Toolkit. First add a CUDA build customization to your project as above. Then, right click on the project name and select Properties. Under CUDA C/C++, select Common, and set the CUDA Toolkit Custom Dir field to $(CUDA_PATH) . Note that the $(CUDA_PATH) environment variable is set by the installer...

You are a practical man with practical suggestions, oscark! Thanks for the tip. I feel sure that the staff will pass it along to prospective project scientists if it seems relevant.

Re: GPU

oscark,

Please do not forget about on which platform most of the applications are developped. It is not the Windows but Ubuntu Linux.

If you are the one of Windows only cruncher, please be patiant by thinking about Linux crunchers. Please....

Sorry, corrected a typo.
