Mac LION 上的 Lapack 版本
Lapack 3.2.1 并不完全安全……但是 netlib 最近在 intel 的帮助下发布了 3.3。
那么有人知道 Lapack 3.3 版本是否会随新 MacPro 一起提供吗?
Lapack 3.2.1 is not fully theard safe right...but 3.3 is which is recently being released by netlib with help of intel.
So do some one know whether or not Lapack 3.3 version would be shipped with new MacPro.

LAPACK 版本就在标题中:
更具体地说,它是 clapack-3.2 的修改版本。 1,其中一些常用例程(例如 LU 因子和求解、Cholesky 分解等)被手动调整的实现所取代。
编辑:请注意,我说的是修改 LAPACK-3.2.1。特别是,除了其他修改之外,例程
slamch
和dlamch
已被修改,使它们既是线程安全的又是可重入的。如果您遇到任何非线程安全的例程,则这是一个严重的错误,您应该报告。The LAPACK version is right there in the header:
More specifically, it's a modified version of clapack-3.2.1, which has had some of the commonly used routines (things like LU factor and solve, Cholesky decomposition, etc) replaced with hand-tuned implementations.
Edit: Please note that I said it is a modified LAPACK-3.2.1. In particular, among other modifications, the routines
slamch
anddlamch
have been modified to make them both thread-safe and reentrant. If you encounter any routines that are not thread-safe, that is a serious bug that you should report.
