| Sticky Revision: |
MPI parallelized dump/load for Constant and Tagged data. run_escriptOnFinley.py runs hybrid MPI/OpenMP.
Copyright updated in all files
Serialized parallel I/O when writing mesh or data to NetCDF file on multiple MPI processors. Added domain method getMPIComm() to complement getMPISize() and getMPIRank().
Added Data::copySelf() [Note: this is exposed as copy() in python]. This method returns a pointer to a deep copy of the target. There are c++ tests but no python tests for this yet. All DataAbstracts now have a deepCopy() which simplifies the implementation of the compy methods.
Merged noarrayview branch onto trunk.
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
DataArray is no longer needed. However, the unit tests still require it.
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.
some fixes from the windows version
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.
netcdf c++ interface removed
problem with reset of faulty PDE rhs fixed.
netCDF can now be switched off at compilation. Consequently load and dump of data objects is not available then.
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.
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)
+ 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.
faster version of the local eigenvalue calculation
restructure escript source tree move src/Data/* -> src remove inc modify #includes and cpppath settings accordingly
reorganised esysUtils to remove inc directory
move all directories from trunk/esys2 into trunk and remove esys2
