building on windows #2
Comments
|
I've never even tried building it on windows. It can be ported. I guess CUDA behaves the same, it's just a matter of low level IO functions. |
|
Yeah I bet it is just a few lines of code. Let me know if there is anything I can do to help out... if you need any more detailed build logs. |
|
Super interested in a version that runs on windows. |
|
Any update on a windows build attempt? |

Not really.
I don’t have time right now. I don’t see how this could happen soon, at least from my side.
If there is some other developer that is willing to do it, I can review the code. But not much more.

I have successfully build CUDAICA on Windows 10 using Visual Studio 2015, and it seems running fast and well now. @fraimondo If you have time, could you please help to review the code a little bit? Both the low-level IO part and the CUDA and BLAS part have issues, and I used some workarounds to bypass them. If you agree, I will upload the code on GitHub. Thanks, |

Hi Yunhui,
That’s great.
Do you have the code on GitHub so I can take a look?

Hello Fraimondo, I have uploaded modified version of CUDAICA on https://github.com/yhz-1995/cudaica_win. I find that the cublas part of "step3" in infomax.cu is very slow, On my machine (i7 7700HQ + Nvidia 1050Ti) a lot of time is spent on transform the triangular matrix "u*u'" into a dense matrix. Instead, your "step3<<<>>>" kernel is very fast, but somehow you disabled it. Once I reenable this kernel, I get a 5x speed up on my machine. |
At one point I thought you had a windows binary available but maybe I am mistaken. Anyway, I am all setup with a msys2/mingw64 build environment and CUDA and visual studio 12. How do I get this to compile? I was able to hobble my way through the configure but then it still fails on the build because of sys/mman.h missing and unistd.h.
