Advantages and disadvantages

Advantages

* C++ API (no OpenCL knowledge required) * Mesh-free, immersed boundary approach allows users to move from CAD directly to computations reducing pre-processing effort * Dynamic compilation enables an additional layer of optimization at run-time (i.e. for a specific parameters set the application was provided with) * Automatic hardware acceleration and parallelization of applications * Deployment of same program on a variety of parallel architectures - GPU, APU, FPGA, DSP, multicore CPUs * Ability to deal with complex boundaries * Ability to incorporate microscopic interactions * Availability of the source code

Disadvantages

* Absence of detailed documentation (besides the Developer Guide generated from the source code comments) * Not all OpenCL drivers are mature enough for the library

Features

ASL provides a range of features to solve number of problems - from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid mechanics and elasticity. * Interfacing:
