PaGMO is described as 'offers a generalization of the island model paradigm able parallelize global and local optimization algorithms using multiple threads/processes'. There are six alternatives to PaGMO for Windows and Linux. The best alternative is ParEGO, which is both free and Open Source. Other great apps like PaGMO are MOEA Framework (Free, Open Source), OPAC (Free, Open Source), modeFRONTIER (Paid) and Open BEAGLE (Free, Open Source).
modeFRONTIER is a multidisciplinary and multi-objective optimization and design environment, written to allow easy coupling to almost any computer aided engineering (CAE) tool, whether commercial or in-house
(PARallel and DIStributed Evolving Objects) is a C++ white-box object-oriented framework dedicated to the flexible design of metaheuristics. Based on EO, a template-based ANSI-C++ compliant evolutionary computation library, it is composed of four modules:
