In silico Experiment

In order to improve performance and benefit from new computing architectures, the core functionalities of the widely used NEURON simulator have been isolated and optimized into a new simulator CoreNEURON. This software tool developed by the Blue Brain Project, helps existing NEURON users to simulate their models faster, better utilizes computing resources and helps to deliver science early. This software tool is developed by the Blue Brain Project in collaboration with Michael Hines at Yale University.

CoreNEURON has been developed with the goal of minimizing memory footprint and maximizing scalability on large supercomputers. It support graphics processing units (GPU), makes use of streamlined versions of data structures, and allows efficient use of compute hardware capabilities such as SIMD units on desktop as well as large supercomputing platforms. The memory usage is reduced by 7x and simulation time improved up to 6x. The CoreNEURON simulator handles spiking network simulations including gap junction coupling with the fixed time step method. This software is also part of the Human Brain Project Brain Simulation Platform.
