cluster computers. Vertical efficiency targets singlenode
performance with platformspecific Sparse Banded
BLAS implementations for good memory performance and cache
efficiency. FEAST also exploits the tremendous floating point
performance and memory bandwidth of modern graphics processors
(GPUs) as numerical
coprocessors. No
current plans to publicly release FEAST in the near future, only
preprocessor etc.

SFEPY

SOFA The SOFA
architecture relies on several innovative concepts, in particular
the notion of multimodel representation. In SOFA, most simulation
components (deformable models, collision models, instruments, ...)
can have several representations, connected together through a
mechanism called mapping. Each representation can then be optimized
for a particular task (e.g. collision detection, visualization)
while at the same time improving interoperability by creating a
clear separation between the functional aspects of the simulation
components. As a consequence, it is possible to have models of very
different nature interact together, for instance rigid bodies,
deformable objects, and fluids. At a finer level of granularity, we
also propose a decomposition of physical models (i.e. any model
that behaves according to the laws of physics) into a set of basic
components.
