Any one using Nvidia's CUDA

kmg365

So my boss says "wouldn't cool if SAS used the GPU's on the graphics card" He provides me with this link, saying see someone else is doing it. click.[^] It took me several emails to explain the difference between actually sucking in a SAS or delimited data and hand coding processing and actually using the horse power to do SAS. Maybe if he increased bid to $2k he can get that as well.

What kind of SAS do you mean? Anyway, just "using the GPU" is easy, CUDA somehow manages to make it harder then it is with OpenGL and a nice shader.. well maybe that's just me.

I thought CUDA was the only way to access the GPU, what did you use?

His reluctance to answer that implies this[^], but I suspect it's actually this[^].

Cuda rocks!

You can't turn lead into gold, unless you've built yourself a nuclear plant.

Well Cuda makes it more elegant for doing GPGPU, which has a slightly different purpose than OpenGL (although you can twist opengl to do gpgpu but it is neither clean nor easy).

Time moves alot faster than in other forums. It's the second one.

How so?

SAS-statistical analysis software. click[^]

OpenGL, but as Pierre Leclercq said, it's not really a clean way to do it

Kinda thought it might be ;) All I know about SAS is that my cousin used to be a SAS contractor.

No but I am planning to use OpenCL. I am not really sure how much they differ.

martin_hughes

At a guess, one's called CUDA and the other OpenCL.

OpenCL should work on ATIs as well

It's used by Google in their search engines. I have an interesting post about GPU's and Amdahls's Law on Nvidia: How can CUDA break Amdahl's Law?[^] If you are thinking of using CUDA, you might want to read the post first, it may or may not help your team make a decision to use CUDA. The truth about CUDA is revealed. ~TheArch :cool:

If you can find me the CUDA Language Spec (Op Code) I will make a IL -> CUDA IL assemble linker for it. I looked around for it a few weeks ago, but could not find it. The alternitive it to use DirectML, but I have no idea when it's comming out?!?! ~TheArch

Lost User

DirectML(sp?) will do it also. A mathematics lib for in the next version of DirectX.

Like this? PTX specs[^] Sadly it doesn't seem to specify the binary encoding..
