Issue while using VLfeat's vl_kdforest_query_with_array

I am trying to use VlFeat's vl_kd_forest_query and vl_kdforest_query_with_array. The documentation is poor. All it says is that vl_kdforest_query_with_array "can" make use of multiple cores for running. Does anyone know if this function already uses multiple cores or is there a way to make use of it? Thanks!

(I know one option is to go through the code, but just wanted to know if anyone already has this information.)

Solution

  • This function uses parallelization via OpenMP as you can see here:

    #ifdef _OPENMP
#pragma omp for
#endif
for(qi = 0 ; qi < (signed)numQueries; ++ qi) {
    /* ... */
}
