High End Performance Tips
Topic Area:
Track: Open VMS
Topic: Performance & Tuning
Type:  Breakout Session

Schedule:
11/09/99   11:30 AM     Duration: 60 Min.     Room: 1B

Presenter:
Dietlinde Kellner
Treasury IT Manager, Bank Austria  

Abstract:
When the application cannot be changed, the hardware is maxed out and the performance needs improvement, drastic methods may be necessary. Understanding sequenced bottlenecks in hardware components from backplanes to controller caches and successive limitations in the operating system design are crucial for the success of tuning efforts. Cache hierarchies and their latencies and bandwidths are critical aspects of IO tuning, SMP scaling issues are important for CPU tuning. Operating system modifications or extensions can be the last way out of a performance dilemma in the high end.

Objectives:
Improve memory utilization by efficient use of caching methods
 
Improve the IO subsystem
 
Identify and reduce CPU bottlenecks  

Prerequisites for attendees:
VMS concepts

Required Skill Level:
Advanced
For experienced professionals in application development & system management; those working on large & complex systems
