Configuring and Managing Wolfram Language Kernels

From within a Wolfram Language session, it is possible to connect to other Wolfram Language engines (kernels) both locally and on remote computers using a variety of connection methods. Such kernels can be used for ad-hoc evaluations, as session kernels of a notebook or bundled for parallel computation. Support for discovering, configuring and managing kernel resources has been modernized over the last three language versions, and is now available in a single coherent way across a wide variety of environments, from ad-hoc collections of workstations to managed clusters, supercomputers and cloud compute services. We give an overview over the kernel connection methods and their intended use cases. Connection methods discussed include local kernels, remote access (SSH), WSTPServer and Wolfram Lightweight Grid.
