About This Manual
Preface
The Accelerator enables you to increase the performance of programs that run on
TNS/R systems. The Accelerator optimizes TNS programs to take advantage of the
TNS/R architecture. The Accelerator processes a TNS object file to produce an
accelerated object file.
Most TNS object code that has been accelerated runs faster on TNS/R systems than
TNS object code that has not been accelerated. Most programs written for TNS
systems do not require changes to run on TNS/R systems, either with or without
acceleration.
The Accelerator Manual describes:
•
How the Accelerator works and how to determine which programs to accelerate
•
The changes that you must make to run your TNS object on TNS/R systems. Most
of these changes only affect low-level TAL programs
•
The changes that you must make to your TNS object code before processing it
with the Accelerator
•
The Accelerator syntax and command options
•
How to set Accelerator options to eliminate certain variances and to increase
program performance
•
How to increase the performance of accelerated programs by reducing the number
of transitions into TNS code and compatibility trap handlers
Audience
This manual is intended for systems and applications programmers familiar with HP
systems, the HP NonStop operating system, and the source languages of the
programs to be accelerated. The manual contains all the information needed to use the
Accelerator.
