Programming a Matrix Multiplication for GPUs with CUDA

CUDA makes it possible to program the GPU with the language C. This article will show you the steps to code a matrix multiplication routine in CUDA:

  • allocate memory on the GPU with cudaMalloc or cudaMallocPitch (for aligned memory allocation)
  • move data to the GPU with cudaMemcpy2D
  • select the kernel domain, write the kernel and run it
  • move results back from the GPU to the host with cudaMemcpy2D
  • free resources with cudaFree

NVIDIA GeForce Graphics Cards Used to Break WIFI Passwords

With graphics cards such the GeForce GTX 280 and parallel brute force based algorithms coded in CUDA (GPGPU techniques), WiFi’s WPA (RC4 based) and WPA2 (AES based) encryption systems are now crackable and the time to crack them compared to CPU based algorithms is reduced by a factor of 100 (or 10,000 %).
