Mario,
  The Amesos2 Epetra adapeter was not extended for Epetra 64 bit. Can you use Tpetra ?

Thanks
Siva

Hi developers /users,

I am trying to use Amesos2 with SuperLU_Dist_4.2. I am having several incompatibility between the 32 bit and 64 bit implementation of the local ordinal variable. If you have a working version of Amesos2 with SuperLU_Dist (using -D_LONGINT), could you give me some ideas of how to compile and use it without errors?

I am getting the following compilation error:

src/packages/amesos2/src/Amesos2_Superludist_def.hpp:819:51: error: no matching function for call to 'Amesos2::Util::get_crs_helper<Amesos2::MatrixAdapter<Epetra_CrsMatrix>, double, long long int, long long int>::do_get(Teuchos::Ptr<const Amesos2::MatrixAdapter<Epetra_CrsMatrix> >, Teuchos::ArrayView<double>, Teuchos::ArrayView<int>, Teuchos::ArrayView<int>, SLUD::int_t&, Teuchos::Ptr<const Tpetra::Map<int, int, Kokkos::Compat::KokkosDeviceWrapperNode<Kokkos::Serial> > >, Amesos2::EStorage_Ordering)'
                                          ARBITRARY);

Thanks,

Mario J.

Reporting a possible bug in Amesos2_Superludist_def.hpp:

When using SuperLU_dist 5.0.0 with Amesos2, the function getValidParamers_impl() is throwing an exception in line:

pl->set("npcol", data_.grid.npcol, "Number of columns in the processor grid. "
              "Must be set with nprow", col_row_validator);

The problem is that “data_.grid.npcol” is equal to zero always! This value must be set up in this line of the superlu_dist constructor solver:

SLUD::superlu_gridinit(data_.mat_comm, nprow, npcol, &(data_.grid));

Previous function is part of the SuperLU_dist library. Using a debugger shows that npcol and nprow are set up correctly inside the previous function, but when leaving the function, then, “data_.grid.npcol” is assigned the value of zero.

Any idea of how to fix it?

Cordially,

Mario J. Juha

Hello Mario,

The Trilinos CMake guide explains how to link Trilinos against pre-installed TPLs: http://trilinos.sandia.gov/Trilinos10CMakeQuickstart.txt<UrlBlockedError.aspx>  Search for "Enabling support for optional Third-Party Libraries".

There's also a handy script for installing various DOE codes (including Trilinos and SuperLU_Dist) and enabling the interfaces between them, available here: https://xsdk.info/download/<UrlBlockedError.aspx>

Best wishes,
Alicia

Dear developers / Users,

I am trying to use SuperLU_Dist in Amesos2, but the information is confusing. Some headers specify the the supported version of SuperLU_Dist is 2.5, other part of the code says it is supported up to version 4.0. Could you clarify this issue?

Also, how do I link my local version of SuperLU_Dist with Amesos2? I can not find an example.

Cordially,

Mario J. Juha
