Scalable Data Parallel Algorithms for Texture Synthesis and Compression using Gibbs Random Fields
This paper introduces scalable data parallel algorithms for image
processing. Focusing on Gibbs and Markov Random Field model
representation for textures, we present parallel algorithms for
texture synthesis, compression, and maximum likelihood parameter
estimation, currently implemented on Thinking Machines CM-2 and CM-5.
Use of fine-grained, data parallel processing techniques yields
real-time algorithms for texture synthesis and compression that are
substantially faster than the previously known sequential
implementations. Although current implementations are on Connection
Machines, the methodology presented here enables

Overview of Wide Area Information Servers
The Wide Area Information Servers system is a set of products supplied by
different vendors to help end-users find and retrieve information over
networks. Thinking Machines, Apple Computer, and Dow Jones initially
implemented such a system for use by business executives. These products
are becoming more widely available from various companies.
What does WAIS do?
Users on different platforms can access personal, company, and
published information from one interface. The information can be anything:
text, pictures, voice, or formatted documents. Since a single
computer-to-computer protocol is used, information can be stored anywhere
on different types of machines. Anyone can use this system since

Portable Parallel Programming with the Message-Passing Interface
William Gropp, Ewing Lusk, and Anthony
The parallel programming community recently organized an effort to
standardize the communication subroutine libraries used for
programming on massively parallel computers such as the Connection
Machine and Cray's new T3D, as well as networks of workstations.
The standard they developed, Message-Passing Interface (MPI), not
only unifies within a common framework programs written in a
variety of existing (and currently incompatible) parallel
languages but allows for future portability of programs between
machines. Three of the authors of MPI have teamed up here to

NCSA CM-5 Overview
The Connection Machine Model 5 (CM-5) from Thinking Machines Corporation
is a massively parallel, distributed memory system that supports both
data parallel and message-passing programming. The I/O subsystem on
the CM-5 includes a Scalable Disk Array (SDA) -- a parallel disk storage
system connected directly to the CM-5 data network that provides high-speed
disk I/O -- and a HIPPI interface that provides high-speed data transfer.
NCSA's CM-5 has:
*512 node processors
*64-bit floating point and integer hardware
*16-gigabytes (Gbytes) of memory
*130-Gbyte Scalable Disk Array
Each node consists of four vector units connected by a 64-bit bus to
a SPARC CPU and a Network Interface chip.

Subject: Nesl: a parallel functional language
A full implementation of the NESL language and environment is now
available via anonymous FTP. NESL is a fine-grained, functional,
nested data-parallel language. The current implementation runs on
workstations, the Connection Machines CM2 and CM5, the Cray Y-MP and
the MasPar MP2.
NESL is loosely based on ML. It includes a built-in parallel
data-type, sequences, and parallel operations on sequences (the
element type of a sequence can be any type, not just scalars). It is
based on eager evaluation, and supports polymorphism, type inference
and a limited use of higher-order functions. Currently it does not
have support for modules and its datatype definition is limited

Many distributed memory machines support connection-based
communication instead of or in addition to connection-less message
passing. Connection-based communication can be more efficient than
message passing because the resources are reserved once for the
connection and multiple messages can be sent over the connection.
While long-lived connections enable more efficient use of the
communication system in some situations, managing connection resources
adds another level of complexity to programming such machines. iWarp

Sorting for Particle Flow Simulation on the Connection Machine
by Leonardo Dagum
RNR Technical Report RNR-90-017
This paper investigates the sorting requirements of
a particle simulation and analyzes the sorting algorithms currently
in use on sequential, vector, and data parallel implementations
of particle flow simulations. Particle simulation requires sorting n
integers in the range [1, O(n)] and takes O(n) running time
on sequential or vector machines.
The data parallel implementation of a particle simulation is shown to
be non--optimal with running time O(n \log n).
Until recently, there have been no optimal parallel integer sorting algorithms.
This paper presents an optimal deterministic algorithm
for parallel sorting in a particle

An SGI Power Challenge has been purchased and will be available
by May 1994. This machine will initially have 32 R4400
processors (150 MHz, 75 Mflop peak), 2 Gbytes of shared memory,
and 80 Gbytes of RAID disk. In July 1994, this machine will be
upgraded to 16 TFP superscalar processors, each running at 75
MHz and 300 Mflop peak speed. This machine will be binary
compatible (for single processor applications) with R4400-based
SGI workstations. In addition, NCSA will experiment this
summer with a Houston-based SGI Challenge Array consisting of
four networked Challenge machines with 20 processors each.
This machine will be used to evaluate both high performance
