[GitHub] [incubator-tvm] yzh119 opened a new issue #6157: [feature request] Support for cuda 11
yzh119 opened a new issue #6157:
URL: https://github.com/apache/incubator-tvm/issues/6157
Currently, if I build tvm with cublas and CUDA 11, I'll encounter the following error:
```
/home/expye/repo/incubator-tvm/src/runtime/contrib/cublas/cublas.cc: In function ‘void tvm::contrib::CallLtIgemm(tvm::runtime::TVMArgs, tvm::runtime::TVMRetValue*, cublasLtHandle_t)’:
/home/expye/repo/incubator-tvm/src/runtime/contrib/cublas/cublas.cc:175:63: error: cannot convert ‘cudaDataType_t’ to ‘cublasComputeType_t’
175 | CHECK_CUBLAS_ERROR(cublasLtMatmulDescCreate(&operationDesc, CUDA_R_32I));
| ^~~~~~~~~~
| |
| cudaDataType_t
```
which is no longer compatible with CUDA 11 [cublasLtMatmulDescCreate interface](https://docs.nvidia.com/cuda/cublas/index.html#cublasLtMatmulDescCreate), which has three arguments:
```
cublasStatus_t cublasLtMatmulDescCreate(
cublasLtMatmulDesc_t *matmulDesc,
cudaDataType computeType);
```
which breaks the old api which only has two arguments.
I'm not sure if there are other breaking changes in CUDA 11 that would make the compilation of tvm failed. I think a macro like `#if CUDART_VERSION >= 11000` could solve the problem mentioned above.
