The compilation time is too long for Intel FPGA OpenCL

I am trying to compile a HLS project with Intel SDK for OpenCL 20.3 on DE10 PRO. This project used to take 5~6 hours to compile on Intel SDK for OpenCL 19.4 on Arria10, but it has taken more than 17 ...

    Hi @myg,

    Thank you for posting in Intel community forum, hope all is well and apologies for the delayed in response.

    Unfortunately the compilation time would depends on multiple factors such as complexity of design or system required which the design are compiled with.

    Hence would suggest the following, which is to check on the minimal recommended required specs for the system to compile which hopefully will shorten the compilation time, more details are in the links below:

    Hope that clarify

    Note: Intel OpenCL technology has been deprecated and would advise to move to oneAPI.

    Best Wishes

Hi @FDJKL,


Thank you for the interest in the OpenCL compiler, unfortunately the software has been deprecated and would advise to move to oneAPI.

However the floating point error does have different cause, example the dynamic range of the floating point used, the sequence of the operands or memory order of the floating point data. Hence there could be many cause.


Perhaps if you could if you face such challenges, please do post a separate thread and we would try our best to advise on that.

Hope that clarify.


Best Wishes
