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] env The 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] env The madness thread environment in case synchronization between threads is needed during startup.

Reimplemented from madness::SystolicMatrixAlgorithm< double >.
