Remote Memory Access Programming in MPI-3
2015
ACM Transactions on Parallel Computing
Preserved Fulltext
The Message Passing Interface (MPI) 3.0 standard, introduced in September 2012, includes a significant update to the one-sided communication interface, also known as remote memory access (RMA). ...
In particular, the interface has been extended to better support popular one-sided and global-address-space parallel programming models, to provide better access to hardware performance features, and to ...

To access this remote memory, we rely on swap protocols adequate for MPI thread support levels. ...
This system is an extension of our previously proposed socket-based Distributed Large Memory System (DLM), which offers large virtual memory by using remote memory distributed over nodes in a cluster. ...
Although the programs shown in Fig. 2 and Fig. 3 appear to be sequential programs, users can implicitly access the remote memory without any knowledge of parallel programming in MPI.

Modern interconnects offer remote direct memory access (RDMA) features. Yet, most applications rely on explicit message passing for communications albeit their unwanted overheads. ...
The MPI-3.0 standard defines a programming interface for exploiting RDMA networks directly, however, it's scalability and practicability has to be demonstrated in practice. ...
