	 MetaMP: An Array Abstraction for Distributed Memory

			    Steve W. Otto
		      Oregon Graduate Institute

ABSTRACT: 
MetaMP is an extension to the message passing environments Express 
or NX that supports distributed, multi-dimensional arrays.  It is
implemented as a pre-processor combined with a C runtime system.  In
the jargon of object-oriented techniques, MetaMP supports
multi-dimensional arrays as distributed objects, and important
patterns of communication and control involving the array are provided
as object methods.

MetaMP abstracts the single most important data structure for
scientific computation, arrays, but many other data structures and
associated mechanism need support.  I will discuss our efforts to make
MetaMP a user-extensible system.  The tradeoffs involved in doing this
versus embedding everything within a compiler is our current
pre-occupation and will be covered.

BIOGRAPHY:
Steve Otto received a PhD in theoretical physics from Caltech in 1983.
After graduation he worked as a PostDoc in the Caltech Concurrent
Computation Program.  He has worked for the NASA Jet Propulsion
Laboratory, Ncube, and he spent a year as a visiting professor at
Southampton University, UK.  He is now an Assistant Professor in the
Computer Science and Engineering Dept of the Oregon Graduate
Institute.  His research concerns programming environments for
massively parallel computers, parallel algorithms, and combinatoric
optimization algorithms.
