Remove solver_.parameters_ #668
base: main
Are you sure you want to change the base?
Conversation
I do see some calls where solver.solver_.parameters_ is not being modifiedbut rather the value is getting used. Example: EXPECT_EQ(solver.solver_.parameters_.absolute_tolerance_[state.variable_map_["Ar"]], 1.0e-12); I am unsure if we need to change these as well? |

Right direction, but we still have some more work to do. Any mechanism-specific thing (like tolerances) need to be moved somewhere else. We should spend some time figuring out where they need to go. Also, the parameters need to be any set of paramters (rosenbrock, backward euler, etc.)

31 - rosenbrock (SEGFAULT)
45 - regression_test_solve (NUMERICAL)
46 - chapman_integration (SEGFAULT)
47 - analytical_rosenbrock_integration (NUMERICAL)

I am not sure what happened but after my latest pull and merge- lot of tests failed. I am looking what caused the test failures |
@sjsprecious we've addressed some of your comments. Also, here is the timing of the cuda tests:

Thanks @K20shores for working on this giant PR. It looks good to me and I just have a few minor questions.

After a second thought, shall we copy the absolute tolerance in the constructor or somewhere instead? The variables_
and rate_constants_
are changed every time step but the absolute_tolerance_param_
is not. Thus we should only need to copy it once.

Anyt ideas where else we can copy these in?

I think we can do it in the constructor of CudaState
here: https://github.com/NCAR/micm/blob/main/include/micm/cuda/solver/cuda_state.hpp#L24-L25, assuming that the absolute_tolerance_param_
is already initialized properly.
@K20shores The CUDA LU decomposition and process set tests seem to take lots of time than what I observed on Derecho. Are they running on Derecho or your local laptop? |
This was on derecho |
Interesting. I just ran the CUDA tests on my branch for the LU decomposition rename PR and it ran much faster.
Can you run it on a scratch directory in case it is an issue due to the filesystem for the home directory? |
Oh man. That's drastically longer. I will try scratch and see what happens |
@sjsprecious I guess it was a scratch issue?
|
@K20shores The new result is consistent with mine now. I noticed that you were running the CUDA tests on your home directory on Derecho and I think that was the problem. |
This PR includes moving Parameters
absolute tolerance and relative tolearnce to state from solver
Note:
I have left
std::vector absolute_tolerance_;
double relative_tolerance_{ 1e-6 };
in rosenbrock_solver_prarameter.hpp as the CUDA tests are failing because tolerance doesnt get copied over to the device. Issue occurs in CudaRosenbrockSolver constructor when doing this->parameters_.absolute_tolerance_.size(); it comes out as zero
We can potential get rid of this line in solver_builder.inl. This is also a temporary. solution.
options.absolute_tolerance_ = state_parameters.absolute_tolerance_;
Along with that i have commented out unit tests till we don't have a solution how to deal with tolerance.
