Chameleon is a dense linear algebra software relying on sequential task-based algorithms where sub-tasks of the overall algorithms are submitted to a Runtime system. Such a system is a layer between the application and the hardware which handles the scheduling and the effective execution of tasks on the processing units. A Runtime system such as StarPU is able to manage automatically data transfers between not shared memory area (CPUs-GPUs, distributed nodes). This kind of implementation paradigm allows to design high performing linear algebra algorithms on very different type of architecture: laptop, many-core nodes, CPUs-GPUs, multiple nodes. Chameleon is a sub-project of MORSE specifically dedicated to dense linear algebra.
