ParaSCIP and FiberSCIP - Parallel extensions of SCIP

Coauthors: Tobias Achterberg, Timo Berthold, Stefan Heinz, Thorsten Koch, Stefan Vigerske, Michael Winkler


SCIP is a powerful Mixed Integer Linear and Non-Linear Programming (MILP/MINLP) solver. We will present the implementation of two parallel extensions of SCIP. One is ParaSCIP, which is intended to run on a large scale distributed memory computing environment and the other is FiberSCIP, intended to run in shared memory computing environments. ParaSCIP has successfully been run on the HLRN II supercomputer utilizing up to 7,168 cores to solve a single difficult MILP. It has also been tested on a Fujitsu PRIMERGY RX200S5 using up to 512 cores. Even though ParaSCIP and FibreSCIP have different capabilities, they are realized using a single software: the Ubiquity Generator (UG) framework. The latest computational results using the both ParaSCIP and FiberSCIP will be presented.
