Backend
What every backend reports about itself.
Inheritors
Properties
isAvailable
Whether this backend can do work on this host. koblas's own implementations always can, so the default is true; a binding reports whether the library it calls resolved.
Each half answers for itself, since a host can provide CBLAS without LAPACKE, or OpenBLAS without UMFPACK. Registration does not consult this: koblas registers its UMFPACK binding on a bare library lookup and lets the binding fall back per call, so a registered backend may still report false here. Read it to report what a host offers, or before installing one explicitly.
isPortable
Whether this is koblas's own implementation rather than a binding to a host library. The compiled-in SIMD kernels are portable however fast they are; only something calling out counts as accelerated.
name
priority
Relative preference among the backends offered for one half (F64Blas, F64Decompositions, F64Kernels or a sparse counterpart). registerBackend picks the highest; the portable reference is 0.
