[Carpet] Carpet Status Report (2006-06-13)

[Erik Schnetter]

During the last month, Ian Hawke contributed the tapered time  
evolution algorithm to Carpet.  This algorithm, described in Lehner,  
Liebling, Reula: gr-qc/0510111, avoids all time interpolation.  This  
reduces the number of time levels that are required for a consistent  
time evolution, but increases the number of required buffer zones.   
Lehner et al. state that, for a given set of resources, this tapered  
algorithm delivers more accuracy.  Note that multiple time levels may  
still be necessary to obtain high order accurate analysis quantities.

  Carpet saw also several smaller improvements:

- Warnings about insufficient storage are now printed later, when  
Carpet knows the exact amount of storage that is requested.  This  
avoid premature unjustified warnings.
- CarpetIOHDF5 supports HDF5 1.8.  (Note that files produced by and  
HDF5 version can be read by any other HDF5 version.)
- The vect class was restructured.
