WebI wanted to try to take advantage of parallelism, but I read here that you have to remove all python objects from a block to run the code in parallel. So I tried rewriting the function like this: @cython.boundscheck (False) @cython.wraparound (False) def black_scholes_cython_parallel (int nopt, double [:] price, double [:] strike, double [:] t ... WebMay 8, 2024 · Cythonで関数に低レベルのメモリアクセスが可能な配列を渡す方法としては、 Numpy配列を直接引数に指定する方法 と、 型付きメモリビューを引数に指定する方法 があります。 ここでは、より直観的な前者の方法から調べていきます。 ネット上の断片的な情報を見ていると、Cythonで高速化に効くのは型指定だけであるように思えてきま … ctfwav文件
