[[File:Image.png|thumb|BlackHoles@Home numerical grid structure, which is ~100x more efficient than other techniques (requiring supercomputers), enabling black hole inspiral and merger calculations to be performed on consumer-grade hardware.]] | |||
BlackHoles@Home leverages recent advances in solving Einstein's equations in [https://github.com/zachetienne/nrpytutorial/blob/master/Tutorial-BSSN_formulation.ipynb solving Einstein's equations in singular curvilinear coordinates] (including spherical-like coordinates), to solve the dynamics of binary black hole inspirals and mergers on consumer-grade hardware. It makes extensive use of and was co-developed alongside our [https://github.com/nrpy/nrpy open-source NRPy+ code generation framework], which makes use of [https://www.sympy.org/ the free & open-source Sympy computer algebra system] to convert complex mathematical expressions into highly optimized C code. NRPy+ was written with BlackHoles@Home in mind as its primary application. | |||
