Proving termination or non-termination of lasso programs is a challenging problem in program verification. To unify state-of-the-art approaches under a common execution framework, we present PaSTTeL, a modular and generic parallel portfolio framework for termination and non-termination analysis of lasso programs. PaSTTeL is designed to: (1) facilitate the integration of new analysis algorithms into the portfolio, (2) execute registered strategies concurrently, and (3) act as a self-contained library component that can be seamlessly embedded into any external project requiring (non-)termination analysis. Initial experiments demonstrate that an instantiation of PaSTTeL performs competitively against state-of-the-art tools.
