digitalmars.D - CUDA with D working after all

While browsing team0xf's repository I found a small, inconspicuous 
project named dcuda that was never officially mentioned: 
http://team0xf.com:1024/dcuda/

This guy managed to compile at least a few CUDA examples with D.
Just tried out MatrixMultiply and the test passed :)

Cool. Although the link doesn't seem to be working. I've also been using CUDA and have my own bindings, although I haven't gotten around to hosting them anywhere yet.

Thanks. At first glance, this looks like it only runs on linux, except according to the source it's Windows only... hmm... cool CUDA 2.0 fixed the nvcuda.dll loading bug. Sweet. I didn't notice it in the change log. I have some wrappers which greatly simplify CUDA use. Would the members of team0xf be interested?

Port 1024 works for me.

I tried it on WinXP Pro SP3, so it works on Windows. Although I could only run the debug version, the release one crashed with access violation.

Fixed Newest 'dcuda' works with CUDA 2.3, contains cufft bindings and simpleCUFFT example.

Here: https://jshare.johnshopkins.edu/xythoswfs/webui/_xy-3638242_1-t_5kUrZSWG It requires D2 and the new phobos and CUDA 2.2. It's only been tested on XP and Vista and D2.031. If you need a D1 version, let me know and I'll hunt down an old revision. The ddocs for cuda.api and cuda.tests has some example usage. The D2 version has some pretty niffty features, like struct support. Let me know if you need any help.

It seems the package does not contain module cuda.cufft?

Opps. Just remove the import statement, the file is currently all comments. I stopped maintaining the fft and blas dll shortly after CUDA 1.0 since I wasn't using them. I've updated the ZIP. Also, as before, if you'd like a copy of the FFT bindings, let me know.

What about that __thread storage class? class Device { protected: static __thread CUdevice dev; // This thread's GPU static __thread int gpu_id = 0; // This thread's GPU id static __thread int rev_major; // The major revision number static __thread int rev_minor; // The minor revision number static __thread size_t totalGM; // Total global memory static __thread string dev_name; // Device name static __thread CUdevprop prop; // This device's properties static __thread CUcontext ctx; // This device's context static __thread isValid = false; // Is the device alive Does this combination of static and __thread work? By the way, are static class members treated as "classic global data"? D 2.030: classic global storage now defaults to TLS (Thread Local Storage). D 2.013: Added __thread storage class for thread local storage. This is for testing purposes only to check out the machinery in the back end. The front end design of this will change.

Well, I could probably eliminate __thread now, but it doesn't seem to be doing any harm. Device is in flux right now, as it's basically transitioning from a class with data to a struct containing a bunch of static functions. I don't have a multi-GPU setup (sadly) so I haven't played around with any of the multi-gpu/context stuff in CUDA.
