default input parameter iter_restart for GMRES is set to 20
Initial version of TFQMR method
restart parameter is changed in GMRES(m)
minor
minor: PCG set as default solver
inital x taken into account in MINRES algorithm
initial version of MINRES algorithm
Jacobian-free Newton method added to Paso
Initial version of GMRES with restart
additional stopping criterion added
a bit of reengineering.
a first verion of a Stokes solver
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
ArithmeticTuple added. It is useful for certain applications of PCG
more flexible stopping criterium for the PCG
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.
This version passes the tests on windows except for * vtk * netCDF The version needs to be tested on altix and linux
Print more convergence info in the verbose output
As the LinearPDE uses coefficients as reduced even if they are handed over as full the projector runs into a problem when reduced and full arguments are used in the same projector. Now the projector resets the coefficients befor starting the projection.
Small bug in ReadMeh call fixed. Test for typ of verbose argument in pdetools.SaddlePointSolver added.
I take it all back! Ignore the last check in.
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.
Cleaned up the python in-line doc to make epydoc work better Configured for shake71 to find NetCDF libraries
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.
small bug fixed
Locator accepts list of locations now
backtraking in the saddlepoint problem (not perfect yet)
uszawa scheme runs with variable viscosity
a class to solving sattle point problems using uszawa scheme (not functional yet)
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.
Large number of changes to Finley for meshing in MPI. - optimisation and neatening up of rectcanglular mesh generation code - first and second order 1D, 2D and 3D rectangular meshes are now available in finley and escript using MPI. - reduced meshes now generated in MPI, and interpolation to and from reduced data types now supported.
formatting errors in epydoc tags fixed
more copyright statements added
Corrected spelling of 'license' in url so that the link actually points to the license.
Updated copyright and licence notices.
rob's strange NoPDE class added
bug fixed
tests for clip, maximum, minimum added
time integration manger added
move all directories from trunk/esys2 into trunk and remove esys2
