Hi Marc,

We have fixed most tests ... under linux+pyopencl+GPU nvidia (fermi+kepler)
* With AMD/intel on CPU driver some tests don't pass (but the library is functional and working)
* With NVidia GT200 few kernel crashes (but the library is functional and working)
* With Nvidia 9600 many kernel are crashing but the library is able to use CPU kernels
* With elder nvidia cards where atomic operation do not exist at all, no way to get it working.

The problem we encounter is that kernel designed for GPU do not behave properly under CPU and vice-versa.

This is fully untested with other platforms like windows or macosX and
with ATI graphic cards but feed-back would be welcome.

To run the tests: run test/test_all.py
to have a small demo: run test/demo_match.py

There is comprehensive sphinx doc. The repository should now be:

Cheers,
