Hi

I find it brilliant.

Thanks

Temat: [pypy-dev] An idea about automatic parallelization in PyPy/RPython

> Hi everyone,

>    I have read some papers about PyPy and I also had some ideas about it.  I have communicated with Mr. Bloz and been advised to send my question here.

>    2. There is no control-flow in trace, which is suitable to the fragment program in GPU. 
>    3. We may use the hint of @elidable in interpreter codes, since the elidable functions are nonsensitive in the execution ordering so can be executed parallel.
