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

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

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

After linking with those, I stumbled over kaleidicassociates/lubeck#3

Today I discovered that mir-glas aims to provide .. static c libraries

so I figured I Can use mir-glas in-place

mir-glas claims to provide blas and glas. For some reason lubeck still wants cblas though.

So, linking with cblas, it finally compiled

however, I again stumbled over the already mentioned bug, this time the program at least exits with code 255 and says something slightly different

I just updated the ticket accordingly

Mathias L. Baumann

@Marenz

though I don't even know why cblas is required, my assumption was that mir-glas would provide all.

Ilya Yaroshenko

@9il

mir-glas is not used in Lubeck

lubeck uses only common cblas / lapack libs. Glas does not provide full cblas

The bug in lubeck code

or even in https://github.com/libmir/mir-blas

Mathias L. Baumann

@Marenz

hmm alright. But I suppose I don't actually need lubeck and just use mir-glas directly

btw, I don't know when opBinary was implemented, but it is soooo nice to be able to write m[] = m1 + m2 (it wasn't possible last time I used it)

me gusta

Mathias L. Baumann

@Marenz

I assume there is no libary that offers something like a lazy gemm abstraction so I could write things like m[] = m1.mtimes(m2) + m3;

It seems not trivial to write something like that myself as I discovered

at least if you want to avoid temporary allocations

Ilya Yaroshenko

@9il

m[] = m1.mtimes(m2) + m3; should be possible with lubeck

I will fix the mtimes bug
Thank you for the report!

Mathias L. Baumann

@Marenz

Yeah, it is with lubeck, but as I understood, lubeck doesn't use mir-glas, right?

Ilya Yaroshenko

@9il

Yes, lubeck does not

Mathias L. Baumann

@Marenz

another question: what exactly does the universal() function do? It doesn't take the slice as a ref-argument so I am wondering if it modifies the original slice in any way or if it just returns a new slice that has a different "view" on the same data? Or would it be a mistake to use the original slice after I called universal() on it?
