| Sticky Revision: |
This is a commit to the trunk of the current windows version undergoing debugging. This trunk will shortly be moved to the branches area of the repository, and the saved trunk version currently over in branches restored to the trunk. Second try after resolving a conflict.
Partial implementation of ReadMeshMPI. Will eventually replace ReadMesh but for now has a different name.
Completed mesh.dump(file) and mesh=LoadMesh(file) by adding TagMap and implementing MPI parallelism. Now allocating ElementFile for ContactElements even if there are none. Removed file Mesh_dump.c since dump/loadMesh are in CPPAdapter/MeshAdapter*.cpp.
dump/LoadMesh methods work except for TagMap, Point elements probably OK but are untested.
Created LoadMesh to read a mesh from a distributed NetCDF file. Can read nodes but not elements yet.
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.
reduced integration schemes are implemented now for grad, integrate, etc. Tests still to be added.
first steps toward reduced element integration order. The escript bit is done but the finley part still needs work.
gmsh file reader for finley
Can now compile and run with MPI on shake71
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.
- added directory pythonMPI to the source tree. this directory contains
the c++ wrapper that is used to run python scripts in parallel for the
MPI version of escript/finley
- updated the SConstruct and ./scons/ess_options.py for conditional MPI
compilation. To compile the MPI version on ESS uncomment the #define
PASO_MPI in ./paso/src/Paso.h and add the command line option
useMPI=yes when running scons.
- fixed a compile time error in the MPI build in
finley/src/CPPAdapter/MeshAdapterFactory.cpp
+ Merge of intelc_win32 branch (revision 741:755) with trunk. Tested on iVEC altix (run_tests and py_tests all pass)
Changes relating to the MPI version of escript The standard OpenMP version of escript is unchanged - updated data types (Finley_Mesh, Finley_NodeFile, etc) to store meshes over multiple MPI processes. - added CommBuffer code in Paso for communication of Data associated with distributed meshes - updates in Finley and Escript to support distributed data and operations on distributed data (such as interpolation). - construction of RHS in MPI, so that simple explicit schemes (such as /docs/examples/wave.py without IO and the Locator) can run in MPI. - updated mesh generation for first order line, rectangle and brick meshes and second order line meshes in MPI. - small changes to trunk/SConstruct and trunk/scons/ess_options.py to build the MPI version, these changes are turned off by default.
rationalise #includes and forward declarations
rationalise all #includes
reorganise finley src tree to remove inc dir and src/finley directory
adjust include file names to allow for new finley source tree structure
copy finleyC and CPPAdapter to finley and finley/CPPAdapter to facilitate scons builds
move all directories from trunk/esys2 into trunk and remove esys2
