Hello all I am a graduate student interested in participation in GSoC 2010. I found some PyPy projects closely related to my background. In particular writing a backend for Intel 64, for JIT compiler, sounds interesting. Also I would like to know more about projects on stackless features. I would be happy to hear any comment on these projects and pointers to documents/paper/code that might be helpful. Last year I participated in GSoC as well. I developed a prototype of an architecture independent SIMD library for Python. This library provides an interface for programmers to write SIMD code in Python and then translates it to low level architecture specific SIMD code using CorePy. The prototype that I developed last year supports intel 64 as I did not have enough time to develop code generators for any other architecture. Best Ehsan
