OpenGL Interpolation Qualifiers (GLSL)
There is an exception to this – high-power graphics cards, we love these. They make games sexy and that makes us sexy. At the heart of these is the GPU, and when Nvidia announces it has a new and wonderful one, it is time to take notice. It's codenamed Fermi, after renowned nuclear physicist, Enrico Fermi.......The silicon has been designed from the ground-up to match the latest concepts in parallel computing. The basic features list reads thus: 512 CUDA Cores, Parallel DataCache, Nvidia GigaThread and EEC Support.Clear? There are three billion transistors for starters, compared to 1.4 billion in a GT200 and a mere 681 million on a G80. There's shared, configurable L1 and L2 cache and support for up to 6GB of GDDR5 memory.The block diagram of Fermi looks like the floor plan of a dystopian holiday camp. Sixteen rectangles, each with 32 smaller ones inside, all nice and regimented in neat rows. That's your 16 SM (Streaming Multiprocessing) blocks with 512 little execution units inside, called CUDA cores.Each SM core has local memory, register files, load/store units and thread scheduler to run the 32 associated cores. Each of these can run a floating point or an integer instruction every click. It can also run double precision floating point operations at half that, which will please the maths department.
