Amirus Mirror Memory
-
Version
1.4.40
A Reflective Memory software solution, using standard
networking components and the processors own internal
exception mechanism. The fault-tolerant design is
optimized for low overhead. and delivers throughput of
over 30Mbits/second with millisecond latency. Included
are comprehensive management and diagnostic utilities,
an integrated help facility, a complete API, and
numerous example programs.
The entry-level license supports sharing up to
512Kbytes of memory; the full license supports 64Mbyes.
Both connect 32 computer systems in a single data
network. Multicast techniques and a sophisticated data
exchange protocol minimizes the probability of data
collision, allowing the system to deliver deterministic
performance on Ethernet or wireless networks.
Fault-tolerance is built-in, with a multiple-node
caching algorithm designed to ensure memory consistency
in the event of node failures on an unreliable network.
This permits a robust reflective memory system to be
implemented even on wireless networks. The design is
peer-to-peer with no single point of failure.
A global lock facility allows cooperating programs to
coordinate access to shared memory, making AmirusMM an
ideal platform for the rapid development of distributed
applications. Locks can be requested at either Shared
or Exclusive levels, allowing efficient and protected
access to read-only and read-write memory structures.
The system can be integrated with an existing hardware
reflective memory ring through a hardware-independent
user-written library (available with installation of an
additional license). Sections of memory on the hardware
side can be mapped into AmirusMM memory, and vice
versa. Data exchange between the two rings can be
configured to be either exception-driven or periodic,
with a data granularity of four bytes.
Simplified MATLAB and VB.NET interfaces are included.
