cuSPARSELt matmul example not working on M=N=K8192

[OrenLeung]

on https://github.com/NVIDIA/CUDALibrarySamples/tree/master/cuSPARSELt/matmul

the example runs fine on the existing small m,n,k, but unfortunately when i change my m,n,k to be 8192, i get a runtime error. any pointers or patches on how to fix it?
