Hi, I'm just curious about the feasibility of running python code in a gpu
by extending pypy.
Disclaimer: I am not a PyPy developer, even if I've been following the
project with interest. Nor am I an expert of GPU - I provide links to
the literature I've read.
Yet, I believe that such an attempt is unlikely to be interesting.
Quoting Wikipedia's synthesis:
"Unlike CPUs however, GPUs have a parallel throughput architecture
that emphasizes executing many concurrent threads slowly, rather than
executing a single thread very fast."
And significant optimizations are needed anyway to get performance for
GPU code (and if you don't need the last bit of performance, why
bother with a GPU?), so I think that the need to use a C-like language
is the smallest problem.
I don't have the time (and probably the knowledge neither) to develop that
pypy extension, but I just want to know if it's possible.
I'm interested in languages like openCL and nvidia's CUDA because I think
the future of supercomputing is going to be GPGPU.
Python is a very different language than CUDA or openCL, hence it's
not completely to map python's semantics to something that will make
sense for GPU.
Try googling: copperhead cuda
Also look at:

What's the point of posting here project which has not released any code?
1) He is packaging it up for release this month:

Before the end of August. I'm working on packaging it up right now. =)
2) Bryan's got a good head on his shoulders and has been working on this
problem or some time. Rather than (or at least before) starting off in a
completely new direction, its worth looking at something that has been
in the works for a while now and is attaining some maturity.
3) You are welcome to ignore it, but some folks might be interested, and
at least they now know it is there and where to look for more
information and forthcoming code.
