Hi all,

Now that I've (finally) finished my honours thesis, I've got time to start working on dcompute again. I'd like to invite anyone interested in helping to develop and/or document (or just interested in general) the drivers for OpenCL/CUDA, the device standard library and other stuff. Please post here or on the MIR gitter (https://gitter.im/libmir/public) if you would like to contribute.

Misc stuff that needs doing:
* Derelict packages for recent OpenCL/CUDA.
derelict-cl currently supports up to 1.2 (latest is 2.1/2.2 released May),
derelict-cuda currently supports 6.5 (latest is 8.0 released September 2016)

* LDC/LLVM releases that support SPIR-V. I've got OSX covered, Windows/Linux would be nice to have. Docker containers etc.

Exposing the OpenCL and CUDA instrinsics as part of the device standard library. Also any other common functionality not covered by the intrinsics.

The main work of dcompute will be developing the drivers for OpenCL and CUDA, automating the horrible APIs with the power of D's meta-programming. And of course building libraries of kernels, which is the fun part.

I will continue to develop the necessary LDC features required, if anyone would like to contribute to that effort I can give you some directions but the compiler suff is a fair bit more complicated.

@Mike Parker, what kind of things do you want me to write for the blog?

P.S: Thanks so much for Vibe, Sönke! Being able to use D made the writing if the server for my thesis so much less painful.

I would like to contribute. Is it possible to provide some small chunked tasks to begin with? I have limited time and attention span right now, so that would help a lot.

Grats!

Yay!

Keep pushing adding SPIR-V backend to LLVM mainline. It seemed to get some traction recently.

Cheers,

PS. please update the SPIR-V CI build for OSX: https://github.com/ldc-developers/ldc/pull/2190

You're welcome and congratulations on finishing your thesis! I'm sure I can say the same once I'll finally be ready to start using DCompute, I would have had to invest lots of work into an inferior system otherwise!

Anything you can expand on beyond your DConf talk. Add a link to the talk video & slides in the introductory paragraph, touch on one or two points you talked about, then expand on them. Or even branch off into info not in the talk. This helps keep the DConf talks in the public awareness (for the subset of the public we care about anyway), alerts people who haven't seen the video what it's about, and gives new information for those who already have.

I'd like to get as many such posts as I can from DConf speakers between now and DConf 2018. Email me if you'd like to brainstorm.

Thanks, I try and subdivide and further flesh out https://github.com/libmir/dcompute/projects

Hi!

I would like to contribute if I can.

I am a C++ developer partially pay attention to D whenever I have extra time. I did some scientific open source programming with D "https://github.com/kerdemdemir/YINS-FFT-DLANG".
and join coding contests with D lang.

I am also very interested with CUDA and GPU since I believe in the future coding will not be done only in CPU. Even simple programs will be a hybrid of CPU and GPU. I wrote some basic stuff like calculating covariance in C++ with using CUBLAS and trust.

I am currently not very familiar neither with D nor with CUDA it been like 2 years I couldn't made anything since I had to finish my master thesis also.

I want to ask now if I can contribute somehow even I am not in a good shape neither with GPU nor D anymore.

Regards
Erdem

Glad you're interested.

If you want to take a look at
https://github.com/libmir/dcompute/tree/master/source/dcompute/driver
and the the OpenCL Driver and start working on something similar for CUDA that's be great.
There will be an article on the D blog soon and I'm sure that a more concrete direction for the library will emerge from the discussion on the forums/Reddit/HN.
