During GTC 2014, Nvidia CEO Jen-Hsun Huang revealed the next-generation GPU, Pascal. This chip is aimed at next-generation super-computers, workstations, gaming PCs and cloud super-computers. The chip is also based on a technology called NVLink, and uses 3D memory to amplify the bandwidth between the GPU and memory sub-system. Pascal fits in a module that's a third the size of a PCIe card. According to Huang, NVLink is chip-to-chip communications. He said that the programming model is basically PCI Express with enhanced DMA capability, and that software can adopt this interface very easily. This solution enables programmers to bind memory between the CPU and GPU, the GPU and GPU, and the second generation cache coherency between the GPU and CPU cache. "One of the benefits of parallel computing is to be able to take all these GPUs and put them in parallel, and treat them like one big massive GPU. If we'd only have the bandwidth to communicate from GPU to GPU," he said during the keynote. "NVLink allows us to do just that." Read more here --> tomshardware.com
