1. Challenge: Complexity and Scalability
Simple Extension
Simple verification to add 1 unit to a N-unit system
No downtime (For the …)
Scalable characteristics
Linear capacity growth
Predictable bottlenecks in extended system
Predictable (soft real time) characteristics
Cost efficient
For systems from <10 to >100 processors
Both horisontal and vertical distibution
Question
Principles for cost efficiency and modularity?

2. Challenge: Enabling Processor Technologies
Potential technologies:
Extreme Processors (see example)
SMP on a chip
Already useful technologies:
System on a chip
Network Processors
Multiprocessors on a board (see example)
Questions:
Generic SW models (e.g, language, OS, modelling tools) ?
Power/performance, cost/performance ?
Soft and Hard real time behaviour for Telecom applications ?
Level of system compatibility ?
