    • setVerbose

      public static void setVerbose(boolean verbose)
      Set the flag which indicates whether the output will be verbose and printing information about the differences between the arrays that are compared.
      Parameters:
      verbose - Whether the output will be verbose

      public static boolean compare(int[] reference, int[] data)
      Returns whether the given arrays are equal
      Parameters:
      reference - The reference array
      data - the actual data array

    • compare

      public static boolean compare(byte[] reference, byte[] data)
      Returns whether the given arrays are equal
      Parameters:
      reference - The reference array

      Returns:
      Whether the arrays are equal within the given limits.
      Throws:
      jcuda.CudaException - If the given epsilon is negative
