libensemble 0.10.2

Library to coordinate the concurrent evaluation of dynamic ensembles of calculations

libEnsemble: A complete toolkit for dynamic ensembles of calculations

Adaptive, portable, and scalable software for connecting “deciders” to experiments or simulations.

• Dynamic ensembles: Generate parallel tasks on-the-fly based on previous computations.

• Extreme portability and scaling: Run on or across laptops, clusters, and leadership-class machines.

• Heterogeneous computing: Dynamically and portably assign CPUs, GPUs, or multiple nodes.

• Application monitoring: Ensemble members can run, monitor, and cancel apps.

• Data-flow between tasks: Running ensemble members can send and receive data.

• Low start-up cost: No additional background services or processes required.

libEnsemble is effective at solving design, decision, and inference problems on parallel resources.
