Get the following error for cuda-samples/Samples/cudaTensorCoreGemm

Initializing...
GPU Device 0: "Tesla V100-SXM2-16GB" with compute capability 7.0

M: 4096 (16 x 256)
N: 4096 (16 x 256)
K: 4096 (16 x 256)
Preparing data for GPU...
Required shared memory size: 68 Kb
Computing...
CUDA error at cudaTensorCoreGemm.cu:474 code=77(cudaErrorIllegalAddress) "cudaEventSynchronize(stop)"

The error goes away if I decrease M_TILES,N_TILES and K_TILES to 168(from 256).

Any ideas about this?

Thanks.
