static Ref<MOIndexSpace> sc::R12IntEvalInfo::gen_project (const Ref< MOIndexSpace > & space1, const Ref< MOIndexSpace > & space2, const std::string & name, double lindep_tol) [static]

Project space1 on space2. This routine computes X2 such that C1.S12.X2 = I, where I is identity matrix and X2 spans subspace of space2. X2 is returned.

static Ref<MOIndexSpace> sc::R12IntEvalInfo::orthogonalize (const std::string & name, const Ref< GaussianBasisSet > & bs, const Ref< Integral > & integral, OverlapOrthog::OrthogMethod orthog_method, double lindep_tol, int & nlindep) [static]

Compute span of bs and create corresponding mospace referred to by name. Number linear dependencies is returned in nlindep

void sc::R12IntEvalInfo::save_data_state (StateOut &) [virtual]

Save the base classes (with save_data_state) and the members in the same order that the StateIn CTOR initializes them. This must be implemented by the derived class if the class has data.

Reimplemented from sc::SavableState.

void sc::R12IntEvalInfo::set_absmethod (LinearR12::ABSMethod abs_method)

Sets the ABS approach to be used (ABS or CABS). Default depends on how the object was constructed.

void sc::R12IntEvalInfo::set_dynamic (bool dynamic) [inline]

Sets whether to use dynamic load balancing in parallel MO transformations. Default is no

void sc::R12IntEvalInfo::set_ints_file (const std::string & filename) [inline]

Sets name of the file used to store transformed integrals. Default depends on how the object was constructed.

void sc::R12IntEvalInfo::set_ints_method (const StoreMethod method) [inline]

Sets the method of storing transformed MO integrals. Default depends on how the object was constructed.

void sc::R12IntEvalInfo::set_memory (const size_t nbytes)

Sets the amount of memory to use for the calculation. Default is determined by DEFAULT_SC_MEMORY.
