A bridge between CgalMesh and dtk

CgalMesh for dtk is the name of an Action de Développement Technologique, aka ADT, that aims at simplifying the use of the Cgal Mesh features so that Inria researchers and engineers can handle them in a quite fast and easy way. After six months, it appears that using Cgal Mesh features in a runtime fashion …

parallel map node in dtkComposer

dtkComposer layer Since the beginning of the dtkComposer layer, the Map and Foreach nodes allow the user to apply the same sub-composition to an input container (Qt container, std::vector, dtkArray, etc .). We can for example read a bunch of files from a given directory, put the result in a QStringList and apply a treatment …

Enforce c++11 flags using cmake

Since CMake 3.2, it is possible to enforce in very simple way the use of c++11 features (see Craig Scott’s blog post for more details). Until now in dtk, we had to test the architecture (Apple, Unix or Windows), then check whether the compiler provides c++11 support or not and eventually set dedicated flags manually.

Using dtk within Fortran code and outlook

In the context of the ADT Simon related to the Inria Project Lab (IPL) C2S@Exa dealing with High Performance Computations (HPC), a lot of efforts were made by the dtk team to develop both API and efficient back-ends for parallel sparse linear algebra. Simultaneously, Tristan Cabel modified the Fortran code TRACES from the Andra Institute …

dtk platforms

Today, several software engineering projects are being developed using dtk architecture (see former post) leading to specific platforms dedicated to very different scientific fields: num3sis, axel, medinria, carbonquant, enas, in@lgae, pib, windpos, sup, fsd3d++. Here follows a brief description of scientific goals for each of them.
