AMG reengineered, BUG is Smoother fixed.
Merging dudley and scons updates from branches
some diagnostics for time step backtracing added
The MPI and sequational GAUSS_SEIDEL have been merged. The couring and main diagonal pointer is now manged by the patternm which means that they are calculated once only even if the preconditioner is deleted.
Hybrid MPI/OpenMP versioned Gauss_Seidel preconditioner is added. To use it, use "SolverOptions.GAUSS_SEIDEL_MPI" in python script.
Don't panic. Updating copyright stamps
Smoother for AMG now can be selected from python. Now only Jacobi and Gauss-Seidel are available as smoothers.
Standard coarsening is added to options list.
The first version of the new AMG preconditioner. It need a lot of polishing for efficiency. Old AMG now called AMLI preconditioner.
Updating Lutz' email
Add new diagnostic information: "net time" (the execution time of solver, excluding the setup time for solver and the execution time of preconditioner)
Updating copyright notices
Minimum size of the coarsest level matrix option added to solver options
paso returns now some diagnostics. SCSL has been removed.
linearPDEs has is now using the SolverOptions class to talk to PASO
same adjustment of nameing
AMG levels parameter moved to options file. Now one can set how many levels AMG will go in SetDefauls. Default value is 3.
fixes for MPI
AMG coupling parameter added to options file.
Current version of AMG uses ILU for relaxation, however it is not stable when schur matrix becames more denser. For example it is not stable for -e paramenter is more 400 in 2D for convection problem
Nearly there with dll'ing paso.
some bugs fixed in coresening methods
GS preconditioner now works for block_size 2 and 3 as well. Sweep parameter introdiced, but not working yet
Firs version of symmetric Gauss-Seidel preconditioner with coloring
Copyright updated in all files
MINRES solver is added to escript. Additional 16 tests are added to run_simplesolve for MINRES and TFQMR solvers
TFQMR solver is added to PASO solver. It is not parallelised yet.
Jacobian-free Newton method added to Paso
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
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.
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.
Prepended all paso source files with new Copyright notice
ILU has been replicated is called RILU (recursive ILU) now. ILU will now be reimplemented.
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
