GADGET is used for a wide range of cosmological N-body/SPH simulations, addressing problems as diverse as the formation of large-scale structure in the universe and the dynamics of colliding and merging galaxies to studies of star formation and its regulation by feedback processes. It has been successfully deployed on many of the high performance computers currently in use and has been used for a variety of visualization applications of the results from such simulations, including movies of galaxy formation.
A variety of additional visual material has also been obtained from simulations performed with GADGET, including a web-site dedicated to data visualization and a multimedia presentation that is used in a class taught at MPA on the research topics addressed by the Galaxy Formation group. More information on the implemented physics and algorithmic and numerical aspects of GADGET-2 can be found in the papers “The cosmological N-body/SPH code GADGET-2”, Springel, Yoshida, and White (2000), New Astronomy 6 and in the paper describing the previous version of the code GADGET-1, which is included in the ‘Documentation’ subdirectory of the distribution.
The introduction of environments in Gadget has also facilitated the addition of a deployment button, allowing developers to promote development versions of their apps to production with a single click. This feature is accompanied by a number of changes to the Gadget editor, helping users view the status of their apps as they are deployed. In particular, production errors are now displayed in development environments utilizing original alert designs to help users avoid mistakes when upgrading their apps. Additionally, the zero-downtime reloader now detects and reports when shop plans change from invalid states like frozen or fraudulent to valid, ensuring accurate error reporting and no downtime for users during upgrades.
