| Summary | 0000231: IMPLEMENTED: improved real/Hermitian Cholesky decomposition | ||||||
| Description |
Improved Cholesky decomposition: * uses ALGLIB BLAS (future improvements in ALGLIB BLAS will improve Cholesky performance) * implemented in cache-oblivious manner: performance (measured in FLOPS) GROWS with matrix size; no tuning for specific CPU is required to obtain good performance. Other changes: * CHOLESKY and HCHOLESKY units are merged with TRFAC unit |
