Why not just offer CUDA assistance now? Nothing says the application has to be OpenCL. Simply put, OpenCL runs on AMD and Nvidia GPUs. CUDA only works with Nvidia. For a BOINC project, you want an app that all of your users can use rather than only half. The only reason to use a CUDA app is if it's a legacy application and no OpenCL version is available. |

I have not found a suitable online course in OpenCL, and therefore cannot convert any application to OpenCL. I have found, and taken, an online course in CUDA, but I'm still looking for information on how to interface to BOINC, and how to get started with compiling CUDA on my own computer instead of the remote computer used in the course.

Can't believe this is still going! Look, This project doesn't do GPU work, end of story. It might sometime in the future.

I have not found a suitable online course in OpenCL... To start..... https://handsonopencl.github.io/ https://software.intel.com/en-us/intel-opencl-support/training http://developer.amd.com/wordpress/media/2012/10/OpenCL-University-Kit-2.0.zip And, of course, youtube. Search David Gohara or AJ Guillon [Edit 2 times, last edit by [VENETO] boboviz at Dec 20, 2017 11:33:23 AM] |

Not entirely true. It would be better to offer a CUDA application for GPU (thus only supporting nVidia) then no GPU applications at all. Use the tools that you have. You can figure out OpenCL later if you really want to. In theory you are right. Realistically, not so much.     [Edit 1 times, last edit by Coleslaw at Dec 20, 2017 10:35:13 PM] |

After about 200 hours of playing with python/numba I got the hang of using cuda on python. The speed should be about 25% of C, but the syntax is much "easier" to cope with. Plus you can make the code run on 'parallel' cpu and then easily switch to 'cuda' by changing one word

I just use my GPUs on the GPUGRID while my CPUs run WCG. I guess GPUGRID is optimized for cuda cores though :-(

No. It would be better to offer OpenCL, since nVidia shouldn't be rewarded for having a closed system (ie. CUDA)! |

I guess in your eyes, nothing is better than something as well. That is the logic you are clearly using to argue this point. In that case the argument is as valid as screaming at a wall...
