# Introduction #
OpenMP (Open Multi-Processing) is an API (Application Programming Interface) that makes it easier to write programs that can run on multiple processors or cores. It's designed for shared-memory parallel programming, meaning all the processors can access the same memory. OpenMP is supported for C, C++, and Fortran.
# Install on CodeBlocks #
1. Download and install Codeblocks and choose the default GNU GCC compiler.
2. Open "Compiler and debugger settings", put `-fopenmp` in "other options", and `-lgomp -pthread` in "Other linker options".
3. Add `C:\Program Files (x86)\CodeBlocks\MinGW\lib\gcc\mingw32\bin` to "Compiler and debugger settings" -> "Toolchain Executables" -> Additional Paths ->Add.
# Verify #
Copy this simple code snippet and compile to see the OpenMP version.
```c
#include
#include
int main() {
// Check whether OpenMP is installed and get the OpenMP version
printf("OpenMP version: %d\n", _OPENMP);
return 0;
}
```
