public interface CPUBackend
extends ComputeBackend

Marker interface for CPU-based compute backends.

All CPU backends (dense linear algebra, sparse, SIMD-enhanced, library-based such as Colt, EJML, JBlas, Commons Math) must implement this interface. The concrete default implementation is DefaultCPUBackend.

Note: SIMDBackend extends CPUBackend for backends that additionally use SIMD vector intrinsics (JDK Vector API or Panama FFM).
