cahlen/kronecker-cuda

Kronecker Coefficients (Symmetric Group)

Computes Kronecker coefficients g(lambda,mu,nu) for S_n from character tables via GPU-parallel triple-sum.

Usage

import torch
from kernels import get_kernel

kernel = get_kernel("cahlen/kronecker-cuda")
result = kronecker.slab(char_table, z_inv, j=0)

Compile (standalone)

nvcc -O3 -arch=sm_90 -o kronecker kronecker/kronecker_gpu.cu -lm
