| Sticky Revision: |
Added new test for BiCGStab in run_simplesolve.py algorithmic change in BICGSTAB: from r=r-wt to r=s-wt
some more work on the transport solver.
new upwinding algorithm (still fails)
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
initialization for FCT solver added.
first steps towards a flux controlled transport solver.
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.
modifications to be compliant with _WIN32. The substitutes for asinh, acosh, atanh are still missing (erf will through an exception)
Had to undo commit to new MPI branch. The changes went into the original and not the branch. The files committed here are exactly the same as revision 969.
Parallelization using MPI for solution of implicit problems. Parallelization for explicit problems has already been accomplished in the main SVN branch. This is incomplete and is not ready for use.
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.
Prepended all paso source files with new Copyright notice
The sparse solver can be called by paso now. the building has been change to reduce some code redundancy: now all scons SCscripts are importing scons/esys_options.py which imports platform specific settings.
a better way of representing the matrix format type is introduced. this is needed for the Paradiso and UMFPACK interface
nicer wahy of representing the natrix format is introduced
move all directories from trunk/esys2 into trunk and remove esys2
Merge of development branch dev-02 back to main trunk on 2005-09-15
