Charm++ is a parallel programming language and runtime system designed to create large-scale scientific applications. This object-oriented framework aids in the development of complex computational simulations by managing objects, which contain both data and methods for processing that data, better than alternative models. The framework's adaptive runtime system allows it to automatically distribute workloads across different processor cores or nodes in a distributed memory environment without requiring explicit message passing between components — improving scalability and performance on multiprocessor systems. Developed at the University of Illinois at Urbana-Champaign, Charm++ is widely used in domains like weather modeling, quantum chemistry simulations, and cosmological research where big computing resources are necessary to process massive amounts of data.
