CHANGES FOR BETA 9
==================

Flesh
=====

1) New functions:
CCTK_RunTime - number of seconds since simulation started
CCTK_CurrentTime - string with current time
CCTK_CurrentData - string with current date
CCTK_ParameterFilename - returns full name of parameter file used
Util_SplitFilename - returns directory and filename from full name

2) Running:

The parameter file can now be read from standard input by adding
a "-" at the end of the executable line, e.g.

./exe/cactus_myconfig -

3) Compilation:

CST will no longer stop for duplicate thorn names in the ThornList
which are in the same arrangement

The thorn list can be specified on the compile line with the new
argument THORNS. This can be used in conjunction with THORNLIST

gmake myconfig-config THORNS="Fancy/NewOne" THORNLIST="OldOne.th"

(Note that the notation for this will probably change slightly
for the next release)

CST now accept USES without a range block in the param.ccl

CST no longer accepts deprecated keyword LOGICAL for BOOLEAN

4) Deprecated:

CCTK_GetInterpHandle -> CCTK_InterpHandle
CCTK_RegisterInterpOperator -> CCTK_InterpRegisterOperator
CCTK_mkdir -> CCTK_CreateDirectory
FMODIFIER -> CCTK_FCALL
FORTRAN_NAME -> CCTK_FNAME

5) Removed deprecated macros

GROUP_SCALAR -> CCTK_SCALAR
GROUP_GF -> CCTK_GF
GROUP_ARRAY -> CCTK_ARRAY

GROUP_PRIVATE -> CCTK_PRIVATE
GROUP_PROTECTED -> CCTK_PROTECTED
GROUP_PUBLIC -> CCTK_PUBLIC

6) Changed names

DISTRIB_CONSTANT -> CCTK_DISTRIB_CONSTANT
DISTRIB_DEFAULT -> CCTK_DISTRIB_DEFAULT

7) Coordinates

Fixed bug in CCTK_CoordLocalRange

8) CYGWIN/Windows compilation updates

Works with latest Cygwin (1.1.6)
Works with Intel icl and ifl compilers
Picks up INCLUDE environment variable when making dependencies
LIBS and LIBDIRS may now be set in the make.config.defn file
Tested under Windows 2000
Preliminary configuration support for HPVM
MPI=HPVM HPVM_DIR='...'
Preliminary configuration support for MPIPro
MPI=MPIPro

(See README.NT for specific details of Cactus on the Windows platform.)

9) AIX

Free format F90 now works.

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

1) CactusBase/Time: Added fixed timestep and changed some parameter names
to be more consistent:

courant_method -> method

options: given
courant_static (was standard)
courant_speed (was courant)
courant_time

courant_outevery -> timestep_outevery

2) CactusBase/Boundary,CartGrid3D: Deprecated functions

ConstantBCVar
ConstantBCVarI
ConstantBCGroup
ConstantBCGroupI
ApplyConstantBC
CopyBCGroup
CopyBCGroupI
CopyBCVar
CopyBCVarI
FlatBCGroupI
FlatBCGroup
FlatBCVarI
FlatBCVar

3) CactusBase/IOUtil

The utility routine to parse variable names in a parameter file string
IOUtil_ParseVarsForOutput has now been generalised and moved to the
Flesh. It is now called CCTK_TraverseString.

4) CactusPUGH/PUGH

No longer parallelises on directions with less than or equal to
2*ghostsize+1 points.

Reduction operators have been removed from CactusPUGH/PUGH and moved
into the new thorn CactusPUGH/PUGHReduce

5) CactusConnect

New arrangement with thorns to add a web server to the simulation, which
can be accessed via any web browser to access information and basic
visualisation for the simulation, as well as providing steering
capabilities. See the WebServer-HOWTO for more details

6) CactusIO/IOJpeg

IO method providing 2D images in jpeg format

Einstein Thorns
===============

CactusEinstein/ADM:
bound = radiation -> bound = radiative



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


KNOWN BUGS IN BETA 9
====================
(See Cactus bug tracking system for a complete list)

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


WHAT TO EXPECT IN BETA 10
=========================

1) Function definitions in CCL files

2) CCL file with configuration information

3) Full hyperslabbing interface

4) C version of Interp

5) More documentation

6) More bug fixes
