Thank you very much, you were right, the default LLVM module was built incorrectly and could only target x86 platforms.
However, I was able to build TVM on Power9 with CUDA10, but if I want to run anything it fails with this error: error: /software/ml/GCCcore/8.3.0/include/c++/8.3.0/type_traits(335): error: identifier "__ieee128" is undefined
Do you have a suggestion or a hint on where to look, as I am quite confused regarding Power9…
You might want to check compiler flags like -mno-float128 to nvcc.
You can override CUDA callback here to pass custom compiler options to nvcc tvm/measure_methods.py at main · apache/tvm · GitHub by using @tvm._ffi.register_fun(override=True)
