Hi! Instead of compiling LLVM, LDC from the source downloading LDC 1.4 is enough right ? It was written they already using LLVM 4.0 in this precompiled version.

And one more question when I use dub build in source folder of DCompute it is giving me this output :

Error: unrecognized switch '-mdcompute-targets=cuda-210'
Error: unrecognized switch '-oq'

kerdemdemir

@kerdemdemir

Does anyone have any idea about what I am doing wrong

Nicholas Wilson

@thewilsonator

If you are building with dub make sure to specify --compiler=/path/to/ldc2

Nicholas Wilson

@thewilsonator

Otherwise it will likely use dmd instead, which won't work. I should probably put that in an FAQ.

kerdemdemir

@kerdemdemir

Yes it compiled! Thanks a lot

I am just curious meanwhile compiling I never did anything for linking CUDA. How LDC,LLVM or DCompute knows the CUDA header&library locations.

Nicholas Wilson

@thewilsonator

derelict-cuda takes care of the dynamic linking

https://github.com/DerelictOrg/DerelictCUDA which is specified as a dependancy for DCompute so dub takes are of that.

Being D we don't need the headers, our definitions again come from derelict-cuda.

Good luck porting your simulation!

Thanks! Soul is willing many things but sadly I am so slow

Should we add a * b to ndslice for 1d vectors?

Guys Hi, this is not directly related with DCompute a bit more general.

I am trying to port my beamforming project to DCompute

https://github.com/kerdemdemir/CUDABeamformer/blob/master/CudaBeamformer/kernel.cu

The link above is using CUDA and C++ and already working

I will port this to DCompute and D . I already started the project

https://github.com/kerdemdemir/DSharpEar

Now it is time to write the CUDA kernel. But I am not sure how to import dcompute.lib( I already compiled dcompute source and created .lib file ) to my project.

Do you have any suggestions?

Do I also need to import other libraries like DerelictCL.lib, DerelictCUDA.lib,DerelictUtil.lib

@JohanEngelen

Upon releasing new mir-algorithm, I hope someone can take care of updating d.godbolt.org. It's very easy, but also easily forgotten. See: mattgodbolt/compiler-explorer-image#31 and mattgodbolt/compiler-explorer#529
Small things! Thanks! :-)

Ilya Yaroshenko

@9il

done mattgodbolt/compiler-explorer-image#39

Thanks!

Ilya Yaroshenko

@9il

proposed new Mir logo

Feedback or alternatives are welcome. I am looking for a soft logo instead of current one

Nicholas Wilson

@thewilsonator

IDK, i like the current one, it looks distinctive. That one looks ...bland.

Ilya Yaroshenko

@9il

We need a bland one :-(

or somtihing soft

Maybe we can change it back after a while

Matt Ranger

@VHRanger

hey guys. I think for the long run (3-5 years) it would be in the best interest for libmir to have an interface with apache arrow. Apache arrow is poised to replace pandas in that timeframe

see here: http://wesmckinney.com/blog/apache-arrow-pandas-internals/

and interfacing efficiently with it would potentially be a killer app. I'm interested in contributing here, just throwing this out there

Ilya Yaroshenko

@9il

Hey Matt @VHRanger . Thank you for letting us know. You can count on our help if you need new mir-algorithm features for Apache Arrow. Also, we can create a repo in libmir org and include you to the organizatoin if you want Apache Arrow be part of the libmir.

Greetings. I try to build a simple project using lubeck, mir-glas and mir-cpuid. I am getting errors and I am not really sure how to deal with them: https://gist.github.com/Marenz/a33645a8ab6e6b8b1d4fa5234c124f6a

I am getting the same result if I write ldmd2

and even if I write --compiler=dmd it's using my system ldc (a very old version) and fails

Mathias L. Baumann

@Marenz

ah.. it seems mir-glas' dub file is hard coding quite a lot of things

Mathias L. Baumann

@Marenz

This is all a bit confusing really

lubeck says it requires blas, cblas and lapack as static libraries.. which confused me as I thought it would be a pure D library
