numexpr.utils
NumExpr is a fast numerical expression evaluator for NumPy.
With it, expressions that operate on arrays are accelerated and use less memory than doing the same calculation in Python.
In addition, its multi-threaded capabilities can make use of all your cores – which generally results in substantial performance scaling compared to NumPy.
Last but not least, numexpr can make use of Intel’s VML(Vector Math Library)

NumExpr是一个针对NumPy的快速数值表达式求值库,能够加速数组操作并利用多线程提升性能。它默认使用4个线程,并且在Intel的VML(Vector Math Library)支持下,可以实现与NumPy相比显著的性能提升,特别是在多核处理器上。
