+MRNet is a customizable, high-performance software infrastructure for
+building scalable tools and applications.  It supports efficient 
+multicast and data aggregation functionality using a tree of processes 
+between the tool's front-end and back-ends.  MRNet-based tools may use 
+these internal processes to distribute many important tool activities, 
+for example to reduce data analysis time and keep tool front-end loads 
+manageable.
+
+MRNet-based tool components communicate across logical channels called
+streams. At MRNet internal processes, filters are bound to these streams to
+synchronize and aggregate dataflows. Using filters, MRNet can efficiently
+compute averages, sums, and other more complex aggregations and analyses
+on tool data. MRNet also supports facilities that allow tool developers
+dynamically load new tool-specific filters into the system.
+
+Features:
+* Flexible tool organization: MRNet does not dictate the organization of
+MRNet and tool processes, so MRNet-based tools can tailor MRNet's
+configuration to the requirements of the tool and its target environment.
+
+* Scalable, flexible data aggregation:  MRNet provides a set of built-in
+filters for traditional data aggregation operations like averages, sums,
+and data concatenation.  MRNet also supports custom, dynamically-loaded
+filters for tool-specific aggregations.
+
+* High-bandwidth communication: Internally, MRNet transfers data using an 
+efficient, packed binary representation. Zero-copy data paths are used 
+whenever possible to reduce data transfer latency.
+
+* Scalable multicast: MRNet supports efficient multicast to reduce the cost
+of delivering tool control messages to tool back-ends.
+
+* Multiple concurrent data channels: MRNet supports multiple logical
+channels of data between tool components. Multiple aggregation and
+multicast operations may be in progress simultaneously.
+
+* Open source licensing.
