| Subject: | [gentoo-dev] Finalizing: GSoC-2019: BLAS/LAPACK Runtime Switching |

| 1 | Hi Gentoo Developers, |
| 2 | |
| 3 | I'm finalizing the GSoC2019 project "BLAS and LAPACK runtime switch".[1] |
| 4 | The |
| 5 | documentation for user and developer is available here: |

| 8 | |
| 9 | BLAS and LAPACK are dense numerical algebra libraries of |
| 10 | "libc-importance" to |
| 11 | scientific computing users. The runtime switching mechanism enables |
| 12 | users to |
| 13 | easily switch the BLAS/LAPACK library system-wide, without recompiling |
| 14 | anything. A similar feature has been long-existing in Debian system, as |
| 15 | known |
| 16 | as the update-alternatives mechanism. In Gentoo we implemented this |
| 17 | feature |
| 18 | with eselect modules. |
| 19 | |
| 20 | This mechanism has been tested by some users and gentoo science team |
| 21 | developers. |
| 22 | Thanks to these early testers, we've got some positive feed backs: |

| 27 | I sincerely invite users and developers who heavily rely on BLAS/LAPACK |
| 28 | libraries to test it. Should you find any problem, or have any |
| 29 | suggestion/question, please let me know :-) |
