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
