I was recently contacted and figured I would forward this response for the public archives, as well as to have anybody else contribute to the conversation...


Hello XXX,


  I don't mind answering your question personally, but in the future, we have a discussion list at lists.opencpi.org that you can subscribe to (and I will likely anonymize your question and post it there). The OSS version of OpenCPI supports OpenCL as an Authoring Model to target GPUs, and possibly CPUs (I'm not sure off-hand, sorry). FPGA Workers at this time are only written in VHDL. The AV team, whose work I push to GitHub, is currently about a dozen engineers, and we are not currently tasked with supporting OpenCL. This could lead to a possible lack of support of your efforts. However, being inactive does not necessarily denote obsolete; it all should work. But, for example, we are not testing it in our Jenkins builds or anything like that.


Hope this helps,


 Aaron

Aaron,

I hope you don’t mind me reaching out to you, but I have a question about OpenCPI. I see that you have most recently been the leading contributor to the project on Github. We are trying to evaluate OpenCPI as a candidate for a project we are starting. We would like to have the ability to write Workers in OpenCL and deploy them on multiple hardware platforms (CPU, GPU, FPGA). Do you know if OpenCPI provides that kind of support? If not, is it on the roadmap for product? I see that OpenCL has recently been configured out of the default configuration, which makes me wonder about this capability.

Thanks,

XXX
