Parallel
Virtual Machine
( PVM )
PVM
(Parallel Virtual Machine) is a software system that enables a collection of
heterogeneous computers to be used as a coherent and flexible concurrent
computational resource. The individual computers may be shared- or local-memory
multiprocessors, vector supercomputers, specialized graphics engines, or scalar
workstations, that may be interconnected by a variety of networks, such as
ethernet, FDDI, etc. PVM support software executes on each machine in a
user-configurable pool, and presents a unified, general, and powerful
computational environment of concurrent applications. User programs written in C
or Fortran are provided access to PVM through the use of calls to PVM library
routines for functions such as process initiation, message transmission and
reception, and synchronization via barriers or rendezvous. Users may optionally
control the execution location of specific application components. The PVM
system transparently handles message routing, data conversion for incompatible
architectures, and other tasks that are necessary for operation in a
heterogeneous, network environment.

pgperl is a version of the Perl 4.0 language which has been combined with the
PGPLOT FORTRAN library, a very popular package for plotting astronomical data.
(As a glance through any issue of ApJ or MNRAS will confirm.) The details of
this involve some complicated C glue routines but are transparent to the user.
perl is a real C-like language with full control structures, and is very fast
and efficient. All the power of perl (and believe me that is a lot) is available
to extract data to plot from multitudes of files in complicated free formats.
PGPLOT
Graphics Subroutine Library
The PGPLOT Graphics Subroutine Library is a Fortran-callable, device-independent
graphics package for making simple scientific graphs. It is intended for making
graphical images of publication quality with minimum effort on the part of the
user. For most applications, the program can be device-independent, and the
output can be directed to the appropriate device at run time.
The pgperl module allows the use of the the PGPLOT graphics library from the
popular Perl scripting language. PGPLOT makes it very easy to process and plot
data using the powerful file and text manipulation facilites built in to Perl.

Phase-diverse
speckle reconstruction of solar data
( PDS )
Award-winning
paper: " Phase-diverse speckle reconstruction of solar data," by John
H. Seldin and Richard G. Paxman, Environmental Research Institute of Michigan.
--ABSTRACT-- Phase-diverse speckle imaging is a novel imaging modality that
makes use of both speckle-imaging and phase-diversity concepts. A phase-diverse
speckle data set consists of one conventional image and at least one additional
image with known phase diversity for each of multiple atmospheric phase
realizations. We demonstrate the use of a phase-diverse speckle data set
collected at the Swedish Vacuum Solar Telescope on La Palma to overcome the
effects of atmospheric turbulence and to restore a fine-resolution image of
solar granulation. We present preliminary results of simultaneously
reconstructing an object and a sequence of atmospheric phase aberrations from
these data using a maximum-likelihood parameter-estimation framework. The
consistency of the reconstructions is demonstrated using subsets of the sequence
of images pairs.

The Auger Observatory is designed to detect and study cosmic rays around and
above the GZK cutoff, i.e. at energies exceeding 1019 eV, with an
unprecented quality and precision. Within our present knowledge, there is no
standard explanation to the production and acceleration of any particle in the
universe at such macroscopic energies. The Auger project is therefore the only
answer the scientific community can propose to solve an astrophysical puzzle of
more than 30 years.

Planck is the third Medium-Sized Mission (M3) of ESA's Horizon 2000 Scientific
Programme. It is designed to image the anisotropies of the Cosmic Background
Radiation Field over the whole sky, with unprecedented sensitivity and angular
resolution. Planck will provide a major source of information relevant to
several cosmological and astrophysical issues, such as testing theories of the
early universe and the origin of cosmic structure.
Planck was formerly called COBRAS/SAMBA. After the mission was selected and
approved, it was renamed in honor of the German scientist Max Planck
(1858-1947), Nobel Prize for Physics in 1918.

Project
Galileo: Bringing Jupiter to Earth
Launched in 1989, the Galileo spacecraft arrived at Jupiter on December 7, 1995,
when it fired its main engine for a successful orbit capture around Jupiter. On
that day, Galileo's atmospheric probe plunged into Jupiter's atmosphere and
relayed information on the structure and composition of the solar system's
largest planet. The spacecraft's orbiter will spend the next two years orbiting
the giant planet, studying Jupiter and its moons (encountering one moon during
each orbit), and returning a steady stream of images and scientific data. The
first two encounters were successfully performed with Jupiter's largest moon,
Ganymede, on June 27, 1996 and September 6, 1996.
