Intel c compiler standard5/31/2023 This option enables optimizations for speed and disables some optimizations that increase code size and affect speed. O1 and -Os (Linux*) or /O1 and /Os (Windows*) You have multiple different options to select which depends on your application scenario. We will enable the most common compiler optimizations in this step. If your application has already been verified either with GNU* compiler or Intel® C++ compiler, you can start the next step for performance tuning. Normally we use -O0 option in this step for easy debugging. You need to make sure the application correctness before you start the performance tuning. The performance tuning needs to be based on a qualified application. Generally speaking, there are 6 steps for the performance optimization with Intel® C++ Compiler.įirst of all, this is the first step to get started.
