Enum SmAllocation 

pub enum SmAllocation {
    Exact,
    Full,
    Ratio {
        max_extra_numerator: u32,
        max_extra_denominator: u32,
    },
}

Controls how Streaming Multiprocessors (SMs) are assigned cubes.

• Exact: Balanced allocation using GCD (e.g., 120 cubes, 16 SMs → 4 SMs × 30 cubes)
• Full: Uses all SMs even if it overallocates (e.g., 120 cubes, 16 SMs → 16 SMs × 8 cubes = 128 total cubes)
• Overallocate: Allows extra SMs within a specified fraction (e.g., up to 25% overuse)

Variants

Exact

Balanced: uses GCD to never exceed total cubes.

Full

Uses all SMs, possibly overallocating total cubes.

Ratio

Allows overallocating SMs up to a ratio.

Fields

max_extra_numerator: u32

max_extra_denominator: u32
