baracuda-cusolver-sys

Raw FFI bindings + dynamic loader for NVIDIA cuSOLVER — dense and sparse linear-system solvers on the GPU. Covers cuSolverDn (dense), cuSolverSp (sparse), cuSolverRf (refactor), and cuSolverMg (multi-GPU dense).

Symbols resolve lazily via libloading; no link-time dependency on libcusolver.so / cusolver64_*.dll / cusolverMg64_*.dll.

Most users want baracuda-cusolver — that crate exposes typed handles for each sub-API plus generic-over-scalar safe wrappers for the common operations (LU, QR, Cholesky, SVD, eigensolvers).

What's exposed

• Dense (cuSolverDn): LU (getrf + getrs), QR (geqrf + orgqr
  • ormqr), Cholesky (potrf + potrs + potri), SVD, syevd, syevj, gesvdj, batched-syevj / batched-gesvdj, gels, plus the generic 64-bit Xgetrf / Xgetrs / Xgeqrf / Xpotrf / Xpotrs / Xsyevd family in S / D / C / Z.
• Sparse (cuSolverSp): csrlsvchol, csrlsvqr.
• Refactor (cuSolverRf): full Rf API.
• Multi-GPU (cuSolverMg): getrf, potrf, syevd.
