About this paper
Shermin Khosravi, David Bremner
Researchers at the University of New Brunswick developed Hierarchical Synchronization Barriers (HSB), a method for compiling algorithms into Linear Programs that significantly reduces LP size and enhances solver performance. HSB achieves this by localizing constraints and variables to specific execution time intervals, moving beyond uniform program unrolling.
Key insights
- Efficient LP generation stems from inferring and localizing program execution to specific time intervals rather than globally unrolling code over all potential steps.
- Introducing structural invariants through hierarchical synchronization barriers at compile time allows for precise localization of LP constraints and variables.
- HSB's localized constraint generation leads to significantly smaller LPs, even when its automatically computed `TB(n)` is larger than a user-optimized manual `TB(n)`.
