Question

确保在Mac Pro上使用MKL库的numpy。

25

我正在使用Enthought的Canopy/EPD版本的Python，其中包含链接到MKL的numpy。我目前在我的工作电脑（Windows 7、四核i5 @ 3.33 Ghz、4 GB内存）和家用工作站（Mac Pro 3.1、Ubuntu 12.04、2个2.8 Ghz四核Xeon、6 GB内存）上并行运行一组模拟。

但是当我对模拟进行基准测试时，它们在工作电脑上运行得更快（每次迭代35秒，而在Mac Pro上则需要60秒）。问题在于核心之间完全平衡（尴尬的并行问题），因此我怀疑linux工作站上的MKL库存在问题。有没有一种方法可以验证Python实际上是否使用了MKL库。我已经阅读了一些线程，说可以检查Python是否链接到它，但这并不能确保它构建正确并且实际上正在使用。

scipy.show_config() 不是你要找的吗？不确定这是否算作“确保”它实际被使用。 - askewchan

当我输入时，所有的“library_dirs”和“include_dirs”都显示为：“/home/vagrant/src/master-env/...”。这正确吗（我的用户帐户不是“vagrant”，当我检查该文件夹时，它不存在）？这个字段很重要吗，还是没有使用？库正确报告“mkl_lapack95_lp64”等。 - user1554752

>>> numpy.show_config()

您将会看到类似这样的输出，表明MKL已经被链接。
