I haven't really tested DeepBench kernels for K80. Are you sure you compiled with the correct SM version? Are the drivers updated to run with CUDA 8.0?
1.) As currently written, gemm_bench will fail for Kepler GPUs for CUDA 8 and later. cublasGemmEx() is only supported on GPUs with SM 5.0 or greater (i.e. Maxwell and newer). https://docs.nvidia.com/cuda/cublas/index.html#cublas-GemmEx
I have changed CUDA version to 7.5 , cuDNN version to 5.0, and now the deepbench can run most of the benchmarks but except the 'nccl_mpi_all_reduce'.
Environment:
Problems:
After make there are five files in .../nvidia/bin , they are:
conv_bench gemm_bench nccl_mpi_all_reduce nccl_single_all_reduce rnn_bench
And I can successfully run 'rnn_bench', 'nccl_single_all_reduce',
How can I fix it?
