## Member Function Documentation

void sc::MsgMemoryGrp::set_localsize | ( | size_t |  | ) | `[virtual]`

Set the size of locally held memory.

When memory is accessed using a global offset counting starts at node 0 and proceeds up to node n() - 1.

Implements sc::MemoryGrp.

Reimplemented in sc::ActiveMsgMemoryGrp, sc::ARMCIMemoryGrp, sc::RDMAMemoryGrp, and sc::ShmMemoryGrp.

void sc::MsgMemoryGrp::sync | ( |  | ) | `[virtual]`

Synchronizes all the nodes.

This is useful after remote memory writes to be certain that all of the writes have completed and the data can be accessed locally, for example.

Implements sc::MemoryGrp.

Reimplemented in sc::ARMCIMemoryGrp, and sc::MTMPIMemoryGrp.
