How is the OpenMP implementation going? I've just received my parallella (finally arriving to the Old Continent) and I was hoping to do a matrix-matrix multiplication benchmark but going through the examples I thought there was not an OpenMP approach to use the Ephiphany coprocessor. Am I right?
My modest opinion is that it would be very important to access the coprocessor using OpenMP and MPI. That would definitely put parallella among other emergent low consumption options in HPC.

Hope is okay to share my ideas...

Regards,
Luiceur

First, a programming quick start using STDCL can be found here:

Second, OpenMP support is being investigated using libcoprthr as a co-processor threading library for Epiphany, proof-of-concept code looks good so far as a basis for a project.

Consider STDCL. Its not a wrapper but it leverages OpenCL for portability, at the moment at least, the way other APIs do, like OpenACC (though its very different from OpenACC). STDCL supports Parallella now with the COPRTHR SDK v1.6 released yesterday. The SDK also provides a more direct API that may be of interest in the context of getting OpenMP to work on Parallella for any project aimed in that direction. Many OpenMP implementations use pthreads for a thread pool. The COPRTHR direct API includes a logical extension of pthreads to co-processors. Parallella is a target for support. That may provide a useful connection in the future.

So there are really two interwoven issues here. If you want a quick example of parallel code for Parallella, STDCL is very simple and there are a lot of tools in place, like clcc that supports a standard compilation model - these things are available now, not future projects.

If you are looking for a programming quick start with examples for Parallella, we are hoping to post something within days. No tedious verbose OpenCL headaches. Just simple clean code.
