(Presented by Kanad Sinha)
There’s only so much optimization that can be performed at compile-time.
“Use of adaptive and dynamic optimization paradigms, where optimization is performed at runtime when complete system and input knowledge is available.”
-May not result in max possible optimization
- Can result in code explosion
+ Single copy of source
- May still not result in max possible optimization
+ Complete input and system knowledge – max optimization possible
- Considerable runtime overhead
3 functions of a dynamic/adaptive optimization system
Runtime system consists of:
Optimization and execution truly asynchronous
Each of these can be replaced dynamically
Optimization process outside critical path/decoupled from execution
* “A full description of ADAPT language is beyond the scope of this paper”, and by extension, this presentation.
