[QST] How to compile and run `examples/35_gemm_softmax` ? #1728

Closed hxdtest closed 1 week ago

hxdtest commented 3 weeks ago

What is your question? When I run examples/35_gemm_softmax， I use nvcc --expt-relaxed-constexpr -I /mnt5/xuantai.hxd/cutlass/include -I /mnt5/xuantai.hxd/run_cutlass/cutlass_gemm_softmax -I /mnt5/xuantai.hxd/cutlass/tools/util/include gemm_softmax.cu -o run -std=c++17 to compile the file. But the ouputs are void cutlass::arch::ldsm(cutlass::Array<unsigned int, MatrixCount, true> &, const void *) [with Layout = cutlass::layout::RowMajor; int MatrixCount = 4] not implemented Device synchronize failed with error unspecified launch failure? Is there anything wrong with compile commands?

Your command line flags are wrong. Please use the cutlass cmake build system or replicate its flags.
