@pasquadambra Like Matt mentioned first error regarding pinned memory allocation is a fatal one. > I am not able to run the code on more nodes by using increasing dimensions....

@pledac does it happen only with static library?

Hmmm, i cannot blame anything inside AMGX from the top of my head, but this is definitely suspicious. To be honest i haven't used shared library myself in a long...

AMGX's CMake doesn't have explicit dependency on OMP. What is cmake configuration did you use to build AMGX?

Hi @Ning-Li-Ambition , Were you successful with `cmake` command from the build instructions? If it was successful, then there should be AMGX Visual Studio solution in the build directory which...

Latest revision builds fine with VS 2019, let me know if you still have build issues.

Thanks for the report! Actually it seems this fix is also slightly incorrect with some input parameters. Will track this internally and fix: AMGX-55

Hey @vmasyagin, You can try looking into following examples: 1) https://github.com/NVIDIA/AMGX/blob/master/examples/amgx_mpi_poisson5pt.c 5pt stencil, data generated in the host buffers 2) https://github.com/NVIDIA/AMGX/blob/master/examples/amgx_mpi_capi_agg.c data read from file to the host buffers where...

My quick guess would be that AMGX doesn't know dimensions of `sln` vector, since you created but it was not initialized, i will check if we set solution dimensions/block size...

No problem. I should note that you are using `AMGX_solver_solve_with_0_initial_guess()` and it would be logical for AMGX to not expect user to set or initialize initial guess manually (since it's...
