Function sphere_kernel_decision 

Source 
pub fn sphere_kernel_decision(n: usize, m: usize, lmax: usize) -> GpuDecision
Expand description

Decide whether the GPU sphere kernel matrix path is eligible for (n, m, lmax). Heuristic per the math spec:

  • n * m >= 1_000_000
  • lmax <= 200
  • device memory budget admits at least one (ld × m) design at ld = ((n + 31) / 32) * 32.
