The Aggregate Remote Memory Copy Interface (ARMCI) library is intended to provide a general-purpose, efficient, and widely portable remote memory access (RMA) operations (one-sided communication) optimized for contiguous and noncontiguous (strided, scatter/gather, I/O vector) data transfers.
In addition, ARMCI includes a set of atomic and mutual exclusion operations.
The development ARMCI is driven by the need to support the global-address space communication model in context of distributed regular or irregular distributed data structures, communication libraries, and compilers.
ARMCI is a standalone system that could be used to support user-level libraries and applications that use MPI or PVM.
ARMCI is a free software and can be download from: http://www.emsl.pnl.gov/docs/parsoft/armci/
Optimized implementations of ARMCI are available for the Myrinet (GM), Quadrics, Giganet (VIA) and Infiniband using Mellanox verbs API.
A port of ARMCI on the Cray XD1 platform has been developed by Cray and is distributed by them.
IBM has a port of ARMCI on IBM BG/L machine.
ARMCI is available on the following platforms:
IBM SPs (based on LAPI)
Cray X1, T3E, SV1, and J90
Unix workstations and servers: Sun, SGI, HP, IBM, Linux
Clusters of Unix and Windows NT workstations/servers
