In this version 1. with DEBUG_PY_STRINGS not defined, it succeeds to run repeated str(a_fn_space) 50000 times. However it fails run_tests and py_tests in the same way it did previously. 2. with DEBUG_PY_STRINGS it uses toPyString, and almost passes run_tests, and gets far further into py_tests, to a point that looks quite different.
Specify return value policy for __str__
Moving the just checked in windows modified trunk onto a branch
This is a commit to the trunk of the current windows version undergoing debugging. This trunk will shortly be moved to the branches area of the repository, and the saved trunk version currently over in branches restored to the trunk. Second try after resolving a conflict.
explicit upwinding scheme added.
finley interface to paso's transport solver added.
Copied a handful of files from trunk-mpi-branch into trunk
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.
New python method getVersion() which returns the Subversion revision from which escript was compiled
Some changes to make things run on windows. There is still a problem with netcdf an long file names on windows but there is the suspicion that this is a bigger problem related to boost (compiler options). In fact runs with large numbers of iteration/time steps tend to create seg faults.
This version passes the tests on windows except for * vtk * netCDF The version needs to be tested on altix and linux
problem with reset of faulty PDE rhs fixed.
reduced integration schemes are implemented now for grad, integrate, etc. Tests still to be added.
first steps toward reduced element integration order. The escript bit is done but the finley part still needs work.
clear name tagging is supported now.
In VC++ boost has problems with numarray arguments from python. This fixes that problem by taking python::object arguments from the python level and converting it into python::numeric::array on the C++ level. This hasn't been tested with VC++ yet. Moreover the two Data methods dealing with big numarrays as argument and return value have been removed.
netCDF can now be switched off at compilation. Consequently load and dump of data objects is not available then.
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.
access to the number of samples added
Added erf (error function) implementation
Tensor products for Data objects are now computed by a C++ method C_GeneralTensorProduct, which calls C function matrix_matrix_product to do the actual calculation. Can perform product with either input transposed in place, meaning without first computing the transpose in a separate step.
the new function swap_axes + tests added. (It replaces swap).
new function _swap. Python wrapper + testing is still missing.
function added to manually free unused memory in the memory manager
coordinates, element size and normals returned by corresponding FunctionSpace mesthods are now protected against updates. So +=, -=, *=, /=, setTaggedValue, fillFromNumArray will through an excpetion. The FunctionSpace class does nut buffer the oordinates, element size and normals yet.
Modified the following python methods in escript/py_src/util.py to call faster C++ methods: escript_trace escript_transpose escript_symmetric escript_nonsymmetric
new FunctionSpace method setTags added
now float**Data is running
test with tagged data pass now
DataVariable removed. it is not used.
+ NEW BUILD SYSTEM
This commit contains the new build system with cross-platform support.
Most things work are before though you can have more control.
ENVIRONMENT settings have changed:
+ You no longer require LD_LIBRARY_PATH or PYTHONPATH to point to the
esysroot for building and testing performed via scons
+ ACcESS altix users: It is recommended you change your modules to load
the latest intel compiler and other libraries required by boost to match
the setup in svn (you can override). The correct modules are as follows
module load intel_cc.9.0.026
export
MODULEPATH=${MODULEPATH}:/data/raid2/toolspp4/modulefiles/gcc-3.3.6
module load boost/1.33.0/python-2.4.1
module load python/2.4.1
module load numarray/1.3.3
More copyright information.
test_utilOnFinley fixed (did run the tests that still fail)
some steps towards eigenvalue and eigenvector calculation
modify whereZero etc methods to also accept a tolerance parameter
rationalise #includes and forward declarations
restructure escript source tree move src/Data/* -> src remove inc modify #includes and cpppath settings accordingly
reorganised esysUtils to remove inc directory
intreface for setting the number of threads from python
Updated link to epydoc generated documentation on the web site.
length method is removed as it is too slow. use length in util.py instead
move all directories from trunk/esys2 into trunk and remove esys2
