CHANGES FOR BETA 7
==================

Infrastructure
==============

1) Added script "GetCactus" which, given a thorn list with CVS repository
information, will checkout the thorns. It is also possible to embed
parameter files in the thorn list, which will be automatically
extracted. The script and sample parameter files are available from
the web pages.

Flesh
=====

1) Added configuration options DEBUG and OPTIMISE
Added build option WARN.

2) Now can use CCTK_ARGUMENTS and DECLARE_CCTK_ARGUMENTS
rather than specifying CCTK_FARGUMENTS, CCTK_CARGUMENTS,
DECLARE_CCTK_FARGUMENTS or DECLARE_CCTK_CARGUMENTS

3) Changed gmake doc to
gmake UsersGuide -> produces UsersGuide.ps (manual for users)
gmake MaintGuide -> produces MaintGuide.ps (manual for maintainers)

4) Added new make targets
gmake cvsstatus
-> processes information from CVS on the status of your checked
out code
gmake cvsdiff
-> reports the differences between your checked out code and the
version in the CVS repository

5) Added new make option PROMPT=no, which should complete the compilation
without giving you any further prompts. Use this in conjunction from
the THORNLIST option to build a new configuration in one step.

6) Changed name of
gmake <config>-thornparfiles
to
gmake <config>-examples

7) Added the capability to specify that an array should have a constant
size on each processor. This is specified in the interface.ccl by
assigning
DISTRIB=CONSTANT
the default value is
DISTRIB=DEFAULT

8) External packages, such as MPI, recognised by the flesh now define e.g.
#define CCTK_MPI
instead of
#define MPI
Both will continue to work for the next release as this is made
consistent, and the work on including external packages is completed.

9) New Architectures:
Cactus port to IBM SP2 finished (should work out of the box with native
MPI). Tested on SP2s at Argonne, NERSC and MHPCC. The default compiler
on the SP2 is xlc.
Initial port to Hitachi SR8000.


10) Added support for the Lahey/Fujitsu Fortran Compiler. This should be
treated as experimental, since we don't have our own version. (Thanks
to Erik Schnetter for the known architectures file).

11) rfrTraverse has been removed, and is replaces by CCTK_Traverse

12) Memory tracing added.

13) Added support for MPICH 1.2.0


Util Thorns
===========

1) Removed deprecated routines in CactusBase/Boundary

2) CactusPUGH/PUGH - Added manual decomposition (donated by
Matei Ripeneau), and changed parameter names for manual processor
topology. See the README in PUGH/doc for more information.

3) CactusPUGH/PUGH - Major changes to remove the old pGF and implement
grid functions as a special case of a grid array.

4) CactusPUGH/PUGH - Implemented support for constant sized arrays on
each processor

5) CactusBase/IOUtil - Append to output data files after restarting
from a checkpoint file

6) CactusBase/IOUtil - can now recover from the latest checkpoint file
in a given directory (so you can submit several consecutive jobs to
a queue without editing the parameter file)

7) Added CactusBench arrangement to contain benchmarking thorns.
Currently there is just BenchADM which contains the staggered leapfrog
evolution method for CactusEinstein/ADM with the macros expanded, and
some optimisations.

8) New thorn: IDScalarWaveC, initial data for the scalar wave equation all
in C

KNOWN BUGS IN BETA 7
====================
(See Cactus bug tracking system for a complete list)


==============================================================================


WHAT TO EXPECT IN BETA 8
========================

1) Fixes for all known bugs in Beta 7.

2) Full support for Hitachi and Exemplar machines.

3) Support for Intel C/C++ compiler with NT.

4) Compiling on DEC Alphas with native MPI

5) Function aliasing

6) New infrastructure for compiling with external packages (e.g.
HDF5, PETSc,...)

7) Example 1D and 2D applications, extensions of computational infrastructure
to support 1D and 2D.
