Multi-simulation coordinator (MUSIC) is a software developed and released by the INCF and Royal Institute of Technology (KTH) School of Computer Science and Communication in Stockholm, Sweden.^[1] MUSIC is designed for interconnecting large scale neuronal network simulators, either with each other or with other tools.^[2] It allows spike events and continuous time series to be communicated between such applications in a cluster computer. The typical usage cases are connecting models developed for different simulators and connecting a parallel simulator to a post-processing tool.

MUSIC provides a standardized software interface (API) on top of the message-passing interface (MPI) for communication among parallel applications for large-scale computational neuroscience simulations. It enables the transfer of massive amounts of event information and continuous values from one parallel application to another, including those using different data allocation strategies.^[3] In the design of the standard interface, care was taken to allow easy adaptation of existing simulators and to permit third-party development and community-sharing of reusable and interoperable software tools for parallel processing. Three simulators currently have MUSIC interfaces: Moose, NEURON and NEST.^[4]

The MUSIC software library and its documentation are publicly available through the INCF Software Center.^[5]
