Ginkgo: The simple-solver-logging program (original) (raw)

The simple solver with logging example..

This example depends on simple-solver, minimal-cuda-solver.

using ValueType = double;

using IndexType = int;

if (argc == 2 && (std::string(argv[1]) == "--help")) {

std::cerr << "Usage: " << argv[0] << " [executor]" << std::endl;

std::exit(-1);

}

const auto executor_string = argc >= 2 ? argv[1] : "reference";

std::map<std::string, std::function<std::shared_ptrgko::Executor()>>

exec_map{

{"cuda",

[] {

}},

{"hip",

[] {

}},

{"dpcpp",

[] {

}},

{"reference", [] { return gko::ReferenceExecutor::create(); }}};

const auto exec = exec_map.at(executor_string)();

auto A = share(gko::read(std::ifstream("data/A.mtx"), exec));

auto b = gko::read(std::ifstream("data/b.mtx"), exec);

auto x = gko::read(std::ifstream("data/x0.mtx"), exec);

Let's declare a logger which prints to std::cout instead of printing to a file. We log all events except for all linop factory and polymorphic object events. Events masks are group of events which are provided for convenience.

std::shared_ptr<gko:🪵:Stream> stream_logger =

std::cout);

Add stream_logger only to the ResidualNorm criterion Factory Note that the logger will get automatically propagated to every criterion generated from this factory.

const RealValueType reduction_factor{1e-7};

using ResidualCriterionFactory =

std::shared_ptr residual_criterion =

ResidualCriterionFactory::create()

.with_reduction_factor(reduction_factor)

.on(exec);

residual_criterion->add_logger(stream_logger);

auto solver_gen =

cg::build()

.with_criteria(residual_criterion,

gko::stop::Iteration::build().with_max_iters(20u))

.on(exec);

auto solver = solver_gen->generate(A);

First we add facilities to only print to a file. It's possible to select events, using masks, e.g. only iterations mask: gko:🪵:Logger::iteration_complete_mask. See the documentation of Logger class for more information.

std::ofstream filestream("my_file.txt");

solver->add_logger(stream_logger);

This adds a simple logger that only reports convergence state at the end of the solver. Specifically it captures the last residual norm, the final number of iterations, and the converged or not converged status.

std::shared_ptr<gko:🪵:Convergence> convergence_logger =

solver->add_logger(convergence_logger);

Add another logger which puts all the data in an object, we can later retrieve this object in our code. Here we only have want Executor and criterion check completed events.

std::shared_ptrgko:🪵:Record record_logger =

gko:🪵:Logger::iteration_complete_mask);

solver->add_logger(record_logger);

Print the residual of the last criterion check event (where convergence happened)

auto residual =

record_logger->get().iteration_completed.back()->residual.get();

auto residual_d = gko::as(residual);

print_vector("Residual", residual_d);

std::cout << "Solution (x):\n";

std::cout << "Residual norm sqrt(r^T r):\n";

write(std::cout, gko::as(convergence_logger->get_residual_norm()));

std::cout << "Number of iterations "

<< convergence_logger->get_num_iterations() << std::endl;

std::cout << "Convergence status " << std::boolalpha

<< convergence_logger->has_converged() << std::endl;

}
