Member Function Documentation

◆ deactivate()

void sc::R12IntsAcc_MemoryGrp::deactivate ( )
virtual

Done reading content - call set_localsize(0) on the associated MemoryGrp This is a collective operation.

This accumulator cannot be activated again.

Reimplemented from sc::R12IntsAcc.

◆ save_data_state()

void sc::R12IntsAcc_MemoryGrp::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::R12IntsAcc.

◆ store_memorygrp()

void sc::R12IntsAcc_MemoryGrp::store_memorygrp ( Ref< MemoryGrp > &  mem,
int  ni,
const size_t  blksize 
)
virtual

Stores all pair block of integrals held in mem mem must be the same as mem_ used to construct this This is a collective operation.

See documentation for R12IntsAcc::store_memorygrp() for more info.

Implements sc::R12IntsAcc.
