Stephane,

 

You might try loopy <https://documen.tician.de/loopy/> .  It allows out of the 
box execution of pyopencl kernels (assuming you have opencl correctly 
installed, etc.), with a simpler pseudo-code-esque syntax.  It sounds more 
along the lines of what you were looking for

thank you,

So, I will start softly with opencl…

 

I was hoping I could avoid the opencl/c++ step. that’s usually a big python 
advantage. I don’t have any clear difficulty yet, I was just planning to 
introduce some concepts and syntaxes and play with some codes (I have several 
Markov Chains - pymc3 codes for instance) and then debug a more elaborate 
pipeline.

for example I’ve seen there are several ways for opening a context while I 
don’t even know why having context is required...

Dear Stephane,

Starting out with parallel computing can be indeed a big challenge.

Could you elaborate on the type of issues you have? Are you having difficulties 
with OpenCl and developing algorithms for parallel processing? Or is it the 
python-opencl interface?





What would be your advise to get started with pyopencl ?


I would suggest to start with a small example in OpenCL and then integrate it 
in python using pyOpenCL. 

See for example: 
https://github.com/pyopencl/pyopencl/blob/master/examples/narray.py

Good luck,

Sven
