Getting Started with CUDA 12.6

Migrating to CUDA 12.6 is straightforward for existing projects.

  1. Download: Grab the installer from the NVIDIA Developer Portal.
  2. Compatibility Check: Ensure your GPU driver is updated to the minimum required version (usually R550+ drivers for full 12.6 functionality).
  3. Build: Update your CMakeLists.txt or Makefile to point to the new toolkit path.

Code Snippet: Checking Version

#include <stdio.h>
int main() 
    int version;
    cudaRuntimeGetVersion(&version);
    printf("CUDA Runtime Version: %d\n", version);
    // Expected output for 12.6: 12060
    return 0;
