Branch commit. Fixed problems with copyFromNumArray Removed version of setTaggedValueFromCPP() which required DataArrayView. Updated tests.
Branch commit. Moved getSliceRegionLoopRange and checkShape into DataTypes.h Some work on methods to set/addTaggedValues without using DataArrayView. To do this I added copyFromNumArray() on DataVector (It buggy at the moment). This build passes the tests but only because copyFromNumArray is not used.
Branch commit. Finished first pass of Data.h - There is still a constructor which takes a DataArrayView as a parameter. Apart from that, there are no direct references to DataArrayView. DataTagged has a new constructor for copying just the tags from an existing object. DataTypes:: now has a scalarShape constant (to avoid creating one everytime you create a scalar).
Branch commit: DataTagged::addTag() = Add a tag with default value. (All uses that I can find apart from test code only require this anyway). DataAbstract now knows its own shape, rank and number of values and have accessors for them. Data Objects also have acessors for these but query their DataAbstracts for the answers. Data::getDataAtOffset() = access to a particular point in the underlying array. (At the moment this call references the DataArrayView, but that will change when I have everything else working). DataTagged::getDataByTag() = same but search by tag. DataTagged::getDefaultValue() = returns default value without obvious reference to DataArrayView C_GeneralTensorProduct_J is my temporary copy of C_GeneralTensorProduct for experimentation. It and a number of other temporary functions live in JoelMods.cpp_ for now.
Branch commit DO NOT PANIC.
Moved shapeToString and noValues from DataArrayView to
DataTypes{.h,.cpp}
Branching to perform experiments on removing DataArrayView
reordering when reading Netcfd files added.
And get the *(&(*&(* name right
Restore the trunk that existed before the windows changes were committed to the (now moved to branches) old trunk.
Make a temp copy of the trunk before checking in the windows changes
The MPI branch is hereby closed. All future work should be in trunk. Previously in revision 1295 I merged the latest changes to trunk into trunk-mpi-branch. In this revision I copied all files from trunk-mpi-branch over the corresponding trunk files. I did not use 'svn merge', it was a copy.
problem with reset of faulty PDE rhs fixed.
The set/getRefVal functions of Data objects have been removed (mainly to avoid later problems with MPI). Moreover, a faster access to the reference id of samples has been introduced. I don't think that anybody will profit form this at this stage but it will allow a faster dump of data objects.
escript data objects can now be saved to netCDF files, see http://www.unidata.ucar.edu/software/netcdf/. Currently only constant data are implemented with expanded and tagged data to follow. There are two new functions to dump a data object s=Data(...) s.dump(<filename>) and to recover it s=load(<filename>, domain) Notice that the function space of s is recovered but domain is still need. dump and load will replace archive and extract. The installation needs now the netCDF installed.
setValueOfDataPoint accepts double value as argument now
I have done some clarification on functions that allow to access individual data point values in a Data object.
The term "data point number" is always local on a MPI process and referes to the value (data_point_in_sample, sample)
as a single identifyer (data_point_in_sample + sample * number_data_points_per_sample). a "global data point number"
referes to a tuple of a processour id and local data point number.
The function convertToNumArrayFromSampleNo has been removed now and convertToNumArrayFromDPNo renamed to getValueOfDataPoint.
There are two new functions:
getNumberOfDataPoints
setValueOfDataPoint
This allows you to do things like:
in=Data(..)
out=Data(..)
for i in xrange(in.getNumberOfDataPoints())
in_loc=in.getValueOfDataPoint(i)
out_loc=< some operations on in_loc>
out.setValueOfDataPoint(i,out_loc)
Also mindp is renamed to minGlobalDataPoint and there is a new function getValueOfGlobalDataPoint. While in MPI the functions getNumberOfDataPoints and getValueOfDataPoint are working locally on each process (so the code above is executed in parallel).
the latter allows getting a single value across all processors.
the new function swap_axes + tests added. (It replaces swap).
new function _swap. Python wrapper + testing is still missing.
Modified the following python methods in escript/py_src/util.py to call faster C++ methods: escript_trace escript_transpose escript_symmetric escript_nonsymmetric
More copyright information.
some steps towards eigenvalue and eigenvector calculation
rationalise #includes and forward declarations
restructure escript source tree move src/Data/* -> src remove inc modify #includes and cpppath settings accordingly
move all directories from trunk/esys2 into trunk and remove esys2
