The stated purposes of
the Binary Black Hole Grand Challenge Alliance are:
problem solving environment
the Nonlinear Einstein equations describing General Relativity, including
adaptive multilevel parallel infrastructure.
To provide controllable convergent algorithms to compute gravitational
waveforms which arise from Black Hole encounters, and which are relevant
to astrophysical events and may be used to predict signals which for
detection by future ground-, and space-, based detectors.
To provide representative examples of computational waveforms.
