digitalmars.D - any BSGP implementation available?

I attended the talk on BSGP at SIGGRAPH Asia and I found BSGP to be very high
level and simple to read and write (though I haven't really done any
programming in it yet). Maybe Kun Zhou ( http://www.kunzhou.net/ ) can help you
regarding the source code. I also wondered about implementing it for D. 

Currently the number of GPU computing "languages" is almost ridiculous, add in
marketing and most developers don't really seem know what's really right for
them or what they should be excited about.

But BSGP introduced several different keyword, I dislike some of them, yet the
compiler implementation
is rather advanced. The small binary executable provides you a full feature of
compile time exec, and 
several passes of optimization.

I've heard that the source was bought by NV corp, so I just want to know if
there's some previous source
available.

Nope. BSGP is a Microsoft Research project so while a compiler is  
available, I doubt the source will be released. However, BSP  
(http://en.wikipedia.org/wiki/Bulk_Synchronous_Parallel) stuff is  
available (i.e. BSFC++  
http://f.loulergue.free.fr/research/bsfcpp/main.html)


 Looking for some research on GPU computing


I've some GPGPU papers written using CUDA and D.  
(http://ciis.lcsr.jhu.edu/Research/Radiation_Oncology) CUDA just got (as  
of 2.1) the ability for the display driver to compile code (it looks like  
it only ptx, which is NVIDIA's portable GPU assembly language, right now).  
Which means you could convert D code to ptx using single assignment and  
then let NVIDIA optimize it. I have D bindings and a high-level api for  
CUDA if you'd like (~sigh~ Someday I'll actually get around to open  
sourcing them)

I thought you've seen the implementation of the compiler :D I doubt if he 
would be that kind to give me the source :) since rumours say it's been sold

That's cool!

Well, if it's true that it's been sold to NVIDIA, then you can expect it  
to be open sourced as the CUDA compiler is based on Open64 and is  
therefore open sourced.
