Compilation:
From the schnaps folder, first
mkdir build
cd build
cmake ..
make
gmsh ../geo/disque.geo -3
ctest
By default, the OpenCL code runs on platform 0, device 0. This can be changed in schnaps via command-line argument. The unit tests run on the default platform/device, which can be changed via
cmake -D_CL_PLATFORM=1 -D_CL_DEVICE=1 ..
By default, computations are done in double-precision. This can be changed via
cmake -DSINGLE_PRECISION:BOOL=ON
./schnaps
The main schnaps program is schnaps. To generate .msh files from .geo files, one run
gmsh .geo -3
The resulting .msh file can be passed to schnaps via command-line arguments (see ./schnaps -h for a list of options).
The main executable schnaps will output to a gmsh file "dgvisu.msh" if the one calls it with ./schnaps -w 1. By default no output is written.
The default arguments for schnaps results in a simulation of 2D transport in a disc. The results can be viewed via
gmsh dgvisu.msh
The default gmsh visualizer is quite coarse, but the visualization can be improved by the setting "Adapt visuzliation grid" in tools -> options -> View [0].
Adapter le fichier source "schnaps.c" pour traiter des cas avec d'autres maillages. Des exemples de maillages se trouvent dans le dossier geo.
There is some basic documentation with doxygen, which can be generated via
cd doc/ doxygen doxyschnaps

Debugging:
valgrind doesn't play terribly well with the AMD drivers. This can be ameliorated by using the provided suppression file, libamdocl.supp, via
valgrind --suppressions=libamdocl.supp
