Revision Log
| Sticky Revision: |
netCDF can now be switched off at compilation. Consequently load and dump of data objects is not available then.
full Data object dump and load now available. Tests added.
dump and load of expanded data via netCDF added. some test are still missing.
ops! escript/src/DataExpanded.cpp should not be in there
johns local setting removed.
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.
Win32 port modifications "or" is not a valid modifier under win intel compiler * Data.cpp - incorrect "or"s * DataExpanded.cpp - incorrect "or"s
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.
data print shows now the element reference number
Some modifications to the binary operations +,-,*/, pow. The code is a bit simpler now and more efficient has there is no reseising required now. the resizing method has been removed as it is very, very inefficient. Even serial code should be faster now. It is now forbidden to do an inplace update of scalar data object with an object of rank >0 as this is very slow (and does not make much sense).
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
+ Merge of intelc_win32 branch (revision 741:755) with trunk. Tested on iVEC altix (run_tests and py_tests all pass)
More copyright information.
eigenvalues: compiles and passes tests on altix now
faster version of the local eigenvalue calculation
rationalise #includes and forward declarations
restructure escript source tree move src/Data/* -> src remove inc modify #includes and cpppath settings accordingly
fixed a broken constructor - simply didn't work
move all directories from trunk/esys2 into trunk and remove esys2
