Revision 1105 - Directory Listing
Modified Thu Apr 19 01:10:49 2007 UTC (15 years, 11 months ago) by gross

The modification fixes a problem with the garbage collection in python. 
The problem seems that a default value of a method argument is seen as
being dependend on the the instance of the class. This produces a
circular dependence and can stop the garbage collection to delete the
object. The situation becomes in particulary bad if the class provides a
__del__ method as it is not clear where to break the circle.

We need to revisit all python classes in escript & Co to remove this
possible problem.

Revision 964 - Directory Listing
Modified Tue Feb 13 05:10:26 2007 UTC (16 years, 1 month ago) by gross

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.

Revision 950 - Directory Listing
Modified Tue Feb 6 07:01:11 2007 UTC (16 years, 1 month ago) by gross

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.

Revision 921 - Directory Listing
Modified Fri Jan 5 00:54:37 2007 UTC (16 years, 2 months ago) by gross

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.

Revision 912 - Directory Listing
Modified Wed Dec 6 03:29:49 2006 UTC (16 years, 3 months ago) by gross

modellib.WriteVTK has been rewritten. Instead of only three data objects scalar,
vector, tensor it takes now up to 20 data objects data0 ... data19 and writes it into a 
single VTK file. There is also the possibilty to define individiual name tags name0,..., name19.
If no name is given the corresponding attribute name of the Link target is used. 
This simplifies the usage and increases efficiency.

Revision 790 - Directory Listing
Modified Wed Jul 26 23:12:34 2006 UTC (16 years, 8 months ago) by bcumming

changes to escript/py_src/pdetools.py and /escript/src/Data.h/.cpp to
make the Locator work in MPI. escript::Data::mindp now returns a 3 tuple,
with the MPI rank of the process on which the minimum value occurs
included. escript::Data::convertToNumArrayFromDPNo also takes the ProcNo
to perform the MPI reduction.

This had to be implemented in both the MPI and non-MPI versions to allow
the necesary changes to the Python code in pdetools.py. In the non-MPI
version ProcNo is set to 0. This works for the explicit scripts tested
thus far, however if it causes problems in your scripts contact Ben or
Lutz, or revert the three files (pdetools.py, Data.h and Data.cpp) to
the previous version.

Revision 700 - Directory Listing
Modified Thu Apr 6 00:13:40 2006 UTC (16 years, 11 months ago) by gross

A few changes in the build mechanism and the file structure so scons can build release tar files:

  * paso/src/Solver has been moved to paso/src 
  * all test_.py are now run_.py files and are assumed to be passing python tests. they can run by 
    scons py_tests and are part of the release test set
  * escript/py_src/test_ are moved to escript/test/python and are installed in to the build directory 
    (rather then the PYTHONPATH).
  * all py files in test/python which don't start with run_ or test_ are now 'local_py_tests'. they are installed i
    by not run automatically.
  * CppUnitTest is now treated as a escript module (against previous decisions).
  * scons realse builds nor tar/zip files with relvant source code (src and tests in seperate files)

the python tests don't pass yet due to path problems.

+ 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
