How did Cactus start?
Cactus originated in the Numerical Relativity community to realise the large scale computing needs and collaborative working practices required to model objects such as black holes, neutron stars and and gravitational waves using Einsteins Theory of General Relativity. In particular, Cactus grew out of codes, experiences, and ideas of members of the NCSA and AEI numerical relativity groups together with a number of friends and collaborators. Since the first Beta release of Cactus 4.0 many suggestions and contributions have also been made by the users.
