I had a crash in when choosing cuda as executor. The matrix csr format and rhs/sol vector are from std::vector
It crashed at "reordering = gko::experimental::reorder::Amd::build().on(g_exec)->generate(matrix);"
It also crashed if "reordering = gko::experimental::reorder::Amd::build().on(g_exec)->generate(matrix->transpose());"
============================================
Here's example code:
// values, col_idx, and row_ptrs are std::vectors
const auto g_exec = exec_map.at("cuda")(); // throws if not valid
// executor used by the application
// initialize matrix and vectors
auto matrix_host = mtx::create(g_exec->get_master(), gko::dim<2>(m_size),
val_array::view(g_exec->get_master(), m_nnz, values.data()),
idx_array::view(g_exec->get_master(), m_nnz, col_idxs.data()),
idx_array::view(g_exec->get_master(), m_size + 1, row_ptrs.data()));
auto matrix = gko::share(gko::clone(g_exec, matrix_host));
auto b_host = vec::create(g_exec->get_master(), gko::dim<2>(m_size, 1));
auto x_host = vec::create(g_exec->get_master(), gko::dim<2>(m_size, 1));
for (IndexType ii = 0; ii < m_size; ii++) {
b_host->at(ii, 0) = res[ii];
x_host->at(ii, 0) = u[ii];
}
auto b = gko::clone(g_exec, b_host);
auto x = gko::clone(g_exec, x_host);
std::shared_ptr<gko::matrix::Permutation<IndexType>> reordering;
reordering = gko::experimental::reorder::Amd<IndexType>::build().on(g_exec)->generate(matrix); //
std::shared_ptr<gko::matrix::Csr<ValueType, IndexType>> mat_reorder;
std::unique_ptr<gko::matrix::Dense<>, std::default_delete<gko::matrix::Dense<> > > b_reorder, x_reorder;
{
mat_reorder = gko::share(matrix->permute(reordering));
b_reorder = b->permute(reordering, gko::matrix::permute_mode::rows);
x_reorder = x->permute(reordering, gko::matrix::permute_mode::rows);
}
std::shared_ptr<gko::LinOpFactory> par_ilu_fact;
par_ilu_fact = gko::factorization::ParIlut<ValueType, IndexType>::build()
.with_fill_in_limit(limit)
.on(g_exec);
auto par_ilu = gko::share(par_ilu_fact->generate(clone(g_exec, mat_reorder)));
auto ilu_pre_factory =
gko::preconditioner::Ilu<gko::solver::LowerTrs<ValueType, IndexType>,
gko::solver::UpperTrs<ValueType, IndexType>,
false>::build()
.on(g_exec);
// Use incomplete factors to generate ILU preconditioner
auto ilu_preconditioner = gko::share(ilu_pre_factory->generate(par_ilu));
