It accepts the expression as a string, analyzes it, +rewrites it more efficiently, and compiles it to faster Python code on the fly. +It's the next best thing to writing the expression in C and compiling it with +a specialized just-in-time (JIT) compiler, i.e. it does not require a compiler +at runtime. + +Also, numexpr has support for the Intel VML (Vector Math Library) -- integrated +in Intel MKL (Math Kernel Library) --, allowing nice speed-ups when computing +transcendental functions (like trigonometrical, exponentials...) on top of +Intel-compatible platforms. This support also allows to use multiple cores in +your computations. + +WWW: http://code.google.com/p/numexpr/ |
