Version 1.6

On January 22, 2009 we released version 1.6. This release contains many small improvements to the codebase, as well as several large improvements. Most prominently, it features a completely redesigned, massively parallel implementation of the halo finding algorithm HOP, as well as attendant improvements to particle data IO and parallel communication. Additionally, the underlying data structures for hierarchical datasets have been rewritten for speed and clarity, enabling the future addition of new multi-resolution data formats to be easily added.

  • (New) Parallel HOP (  http://arxiv.org/abs/1001.3411 )
  • (Beta!) Software ray casting and volume rendering (Sam Skillman has a gallery here:  http://casa.colorado.edu/~skillman/simulation_gallery/simulation_gallery.html )
  • Rewritten, faster and better contouring engine for clump identification
  • Spectral Energy Distribution calculation for stellar populations
  • Optimized data structures such as the hierarchy
  • Star particle analysis routines
  • Halo mass function routines
  • Completely rewritten, massively faster and more memory efficient Particle IO
  • Fixes for plots, including normalized phase plots
  • Better collective communication in parallel routines
  • Consolidation of optimized C routines into amr_utils
  • Many bug fixes and minor optimizations

HELP!

If you're having trouble with installation or usage, please feel free to email the  users' list. Alternatively, please feel free to contact one of the developers, whose names are sprinkled throughout the source code. (But be forewarned, they might change CC the mailing list on any replies, in case somebody else is having a similar problem!)
