Compilation error with cuda 11.1: error: a nontype template parameter may not have class type

[eddy16112]

Here is my cmake cmd, I am using gcc-9.4 and cuda-11.1

cmake -DCMAKE_INSTALL_PREFIX=../install -DCMAKE_CXX_COMPILER=/scratch2/wwu/kokkos/bin/nvcc_wrapper -DBUILD_SHARED_LIBS=ON -DCMAKE_CXX_STANDARD=17 ..

Here is the output of cmake

Then when I compile the code, I am getting a lot of same errors:

/scratch2/wwu/kokkos-kernels/blas/tpls/KokkosBlas1_rotg_tpl_spec_decl.hpp(452): error: invalid partial specialization -- class "KokkosBlas::Impl::Rotg<Kokkos::Cuda, Kokkos::View<Kokkos::complex<float>, Kokkos::LayoutRight, Kokkos::Device<Kokkos::CudaUVMSpace::execution_space, Kokkos::CudaUVMSpace::memory_space>, Kokkos::MemoryTraits<1U>>, Kokkos::View<float, Kokkos::LayoutRight, Kokkos::Device<Kokkos::CudaUVMSpace::execution_space, Kokkos::CudaUVMSpace::memory_space>, Kokkos::MemoryTraits<1U>>, true, true>" is already fully specialized

/scratch2/wwu/kokkos-kernels/blas/tpls/KokkosBlas1_rotg_tpl_spec_decl.hpp(454): error: a nontype template parameter may not have class type

I will try to reproduced, this is somehow not triggered by our builds...

[eddy16112]

Thanks, here is the full log including kokkos and kokkos-kernels https://gitlab.com/StanfordLegion/legion/-/jobs/3246259273

[lucbv]

FYI, I have reproduced the issue on our systems and will work on a fix. This is related to the ETI process so should not be too complicated to fix.

[lucbv]

The fix in PR #1578 worked on our systems, let me know if you want to test this before we merge it otherwise it should be picked up by your CI when the PR is merged.

[eddy16112]

I am getting new errors:

/scratch2/wwu/kokkos-kernels/sparse/src/KokkosSparse_spgemm_handle.hpp(238): error: identifier "cusparse_spgemm_handle_t" is undefined

/scratch2/wwu/kokkos-kernels/sparse/tpls/KokkosSparse_spmv_tpl_spec_decl.hpp(126): error: identifier "CUSPARSE_SPMV_ALG_DEFAULT" is undefined

/scratch2/wwu/kokkos-kernels/sparse/tpls/KokkosSparse_spmv_tpl_spec_decl.hpp(140): error: identifier "CUSPARSE_SPMV_CSR_ALG2" is undefined

[lucbv]

Okay, I am merging the current PR #1578 and will have a look at the error reported above, these are new and I am not sure who modified that code recently?

[vqd8a]

@lucbv @eddy16112 The error identifier "cusparse_spgemm_handle_t" is undefined could be similar to the error in #1564 .

[lucbv]

Thanks @vqd8a for pointing this issue out, I will check with Brian on his PR status, assuming that it only fixes the spgemm side of the problem we still need to look a bit at the spmv issue.
