Struct GroupedProblem 

pub struct GroupedProblem<'a, T: Element> {
    pub m: i32,
    pub n: i32,
    pub k: i32,
    pub a: MatrixRef<'a, T>,
    pub b: MatrixRef<'a, T>,
    pub c: Option<MatrixRef<'a, T>>,
    pub d: MatrixMut<'a, T>,
    pub alpha: T::Scalar,
    pub beta: T::Scalar,
}

One per-group entry for a grouped GEMM launch.

Each group has its own shape and pointers; CUTLASS dispatches them in a single kernel invocation. Passed as a slice to GroupedGemmPlan::prepare, which returns a PreparedGroupedGemm whose run method performs the launch.

Fields

m: i32

Group M.

n: i32

Group N.

k: i32

Group K.

a: MatrixRef<'a, T>

Left input.

b: MatrixRef<'a, T>

Right input.

c: Option<MatrixRef<'a, T>>

Optional accumulation source.

d: MatrixMut<'a, T>

Output.

alpha: T::Scalar

α for this group. Scalar type matches T::Scalar — f32 for f16/bf16/f32/F32Strict, f64 for f64.

beta: T::Scalar

β for this group. Forced to 0 internally when c is None.
