Member Function Documentation

◆ converged()

bool madness::SystolicFixOrbitalOrders::converged ( const TaskThreadEnv env) const
inlinevirtual

Invoked simultaneously by all threads after each sweep to test for convergence.

There is a thread barrier before and after the invocation of this routine

Parameters
[in]envThe madness thread environment in case synchronization between threads is needed during computation of the convergence condition.

Implements madness::SystolicMatrixAlgorithm< double >.

References nswitched.

◆ end_iteration_hook()

void madness::SystolicFixOrbitalOrders::end_iteration_hook ( const TaskThreadEnv env)
inlinevirtual

Invoked by all threads at the end of each iteration before convergence test.

There is a thread barrier before and after the invocation of this routine. Note that the converged() method is const whereas this can modify the class.

Parameters
[in]envThe madness thread environment in case synchronization between threads is needed during startup.

Reimplemented from madness::SystolicMatrixAlgorithm< double >.

References madness::SystolicMatrixAlgorithm< T >::get_world(), madness::World::gop, madness::TaskThreadEnv::id(), nswitched, and madness::WorldGopInterface::sum().

◆ start_iteration_hook()

void madness::SystolicFixOrbitalOrders::start_iteration_hook ( const TaskThreadEnv env)
inlinevirtual

Invoked by all threads at the start of each iteration.

There is a thread barrier before and after the invocation of this routine

Parameters
[in]envThe madness thread environment in case synchronization between threads is needed during startup.

Reimplemented from madness::SystolicMatrixAlgorithm< double >.
