Error message : "Error: Optimizer FAILED -dbg-info-enabled --grif --soft-elementary-math=false --fas=false --wiicm-disable=true "kernel_top.1.bc" -o "kernel_top.kwgid.bc"

Environment

  • Intel® Quartus® Prime Pro Edition
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    Due to a problem with the Intel® FPGA SDK for OpenCL™ software technology, you may see this error after a long compilation time. This is caused by a large number of storage operations to undefined elements performed by the h_updating_graph_mask_buf_0 and h_graph_visited_buf_0 arrays functions.

    Resolution

    To fix this problem add the following lines in the kernel_top.cl file:

    ***************
    *** 22,30 ****
        
      #pragma ACCEL interface
    variable=k depth=1
        bool stop;
        do {
    -     bool h_updating_graph_mask_buf_0[1000000];
    -     bool h_graph_visited_buf_0[1000000];
      //if no thread
    changes this value then the loop stops
          stop =
    false;
      //omp_set_num_threads(num_omp_threads);
    --- 22,30 ----
        
      #pragma ACCEL interface
    variable=k depth=1
        bool stop;
      bool
    h_updating_graph_mask_buf_0[1000000];
      bool
    h_graph_visited_buf_0[1000000];
        do {
      //if no thread
    changes this value then the loop stops
          stop =
    false;
      //omp_set_num_threads(num_omp_threads);

    This problem will be fixed in a future release of the Intel FPGA SDK for OpenCL
