Hello there,
This is my first post at codeplay.
I am a ML developer working with FPGA platform. As of now, my code is written in OpenCL. I came across a suggestion to give a try at ComputeCPP-tensorflow-openCL acceleration. I tried running the executable computecpp_info from bin folder.
I received the following output which clearly says that the ‘device is Not supported’ because of unavailability of SPIR.
Toolchain information:
GLIBC version: 2.27
GLIBCXX: 20160609
This version of libstdc++ is supported.
Device Info:

Still I just want to confirm once from the experts that is it possible to use intel arria 10 fpga with ComputeCPP?
Thanks in advance
