Algebra Backends

OSQP supports several algebra backends that can be used to create and solve QP problems. Currently, these are builtin, MKL, and CUDA. The builtin backend is the default, and always available, regardless of whether you’re using the C interface directly, or any of the language bindings.

The solver types osqp_linsys_solver_type that are available to you depend on the backend that you’re using. The following table lists the solver types available for each backend:

Backend/Solver Type	Direct Solver	Indirect Solver
builtin	✔	✘
MKL	✔	✔
CUDA	✘	✔

Not all backends are available for all language bindings. The following table lists support for various backends depending on the language wrappers that you’re using for OSQP.

The Codegen column indicates whether code-generation is supported for a particular language binding.

	builtin	MKL	GPU	Codegen
Python	✔	✔	✔	✔
Julia	✔	✔	✔	✘
Matlab	✔	✘	✘	✔
