Parallel Program Development Toolkit (ppdt) - IBM SP parallel execution simulation

abstract

The Parallel Program Development Tookit (ppdt), is a suite of tools for
simulating the behavior of an IBM SP parallel program written using the
IBM Message Passing Applications Programming Interface Library. The
main program is a simulator object module that a user links with the object
modules for the program. It allows the parallel program to run on a single
RS/6000 processor, shifting back and forth among the sections of code that
execute on different processors. It also models the communications
latency and bandwidth for each message. A configuration file allows one to
vary communications characteristics, giving the capability to predict the
performance of a code on a machine that the user doesn't have.
