Detailed Description

The ARMCIMemoryGrp concrete class provides an implementation of MsgMemoryGrp.

It uses the ARMCI interface.

Member Function Documentation

void sc::ARMCIMemoryGrp::free_local (void * data) [virtual]

Free data that was allocated with malloc_local_double.

Reimplemented from sc::MemoryGrp.

void* sc::ARMCIMemoryGrp::malloc_local (size_t nbyte) [virtual]

Allocate data that will be accessed locally only. Using this for data that will be used for global operation can improve efficiency. Data allocated in this way must be freed with free_local_double.

Reimplemented from sc::MemoryGrp.

void sc::ARMCIMemoryGrp::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.

void sc::ARMCIMemoryGrp::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.
