- numerous changes in GPU_TWINCHIRP (in progress)
- possible fix for iGPU build on Skylake (FP_CONTRACT disable (thanks to Juha(http://setiathome.berkeley.edu/show_user.php?userid=1019453) for hint); -cl_mad_enable removed )

    Let me know if you want all those previous attempts.

    And Eric gave link to new

    (moderation:
      )

      And Eric gave link to new location of SETI sources.

      But not so easy to find needed commit there.

      So lets look on this change log.

      Those times E@h used same OpenCL-based FFT library as we used. If it's still the case these changes can be implemented directly.

       

      Seems oclFFT can be build with 

       -cl-mad-enable

      option (here build call: 

      err = clBuildProgram(plan->program, 1, &device_id/*devices[i]*/, "-cl-mad-enable -w", NULL, NULL);

      )

      but this build flag, FP_CONTRACT, should be switched off (we disabled it through whole app, in my kernels too, not only in oclFFt)

      And in oclFFT it can be added here:

      OpenCL_FFT/fft_base_kernels.h

      #pragma OPENCL FP_CONTRACT OFF\n

       

      That's what that log says.

      EDIT: commit comment says -cl-mad-enable removed but log contains that lines as+, not as -.

      Well, initially there was no this flag so perhaps worth to try w/o it.
