<abstract>
pC++ is a portable parallel C++ for high performance computers. pC++ is a
language extention to C++ that permits data-parallel style opertations using
"collections of objects" from some base "element" class. Member functions
from this element class can be applied to the entire collection in parallel.
This allows programmers to compose distributed data structures with
parallel execution semantics. These distributed structures can be aligned and
distributed over the memory hierarchy of the parallel machine much like
HPF. pC++ also includes a mechanism for encapsulating SPMD style
computation in a thread-based computing model.

pC++ code is extremely portable. Just like Cfront translates C++ code into
standard ANSI C that can be passed to the native C compiler, the pC++
preprocessor (written using Sage++) translates pC++ into C++, which is then
compiled on the target architecture. Currently, pC++ has run-time systems
for the following parallel machines:

   Thinking Machines CM5
   Silicon Graphics Challenge
   Kendall Square KSR1
   Intel Paragon
   Meiko CS2
   IBM SP1
   BBN TC2000
   Sequent Symmetry
   homogeneous networks of workstations (PVM)

Furthermore, code can be developed and tested on the following
"uniprocessor" workstations:

   HP hpux
   DEC Decstation (MIPS based)
   DEC Alpha
   Sun4
   Cray C90
   SGI Irix
   IBM RS6000
   NeXT

<title>Sage++
<abstract>
Sage++ is an object-oriented compiler preprocessor toolkit. Using Sage++ to
transform source code is a three step process:

   PARSING: Source code, either FORTRAN, pC++, or C, is parsed
   and saved as a machine-independant parse tree (".dep" file).
   RESTRUCTURING: The ".dep" file is read by a Sage++-built
   restructuring tool. Sage++ uses member functions to manipulate the
   parse tree. For example, a restructuring program written with Sage++
   could identify function-call sites, add variables, optimize loops, add
   tracing functions, or globally replace variables. After the parse tree
   has been modified, the new ".dep" file is saved.
   UNPARSING: The new ".dep" file is "unparsed", recreating the
   source code and reflecting the changes that were made to the parsed
   form. After unparsing, the source code can be compiled with the
   native compiler.
