Innovations in GPUDirect

Whether you are exploring mountains of geological data, researching solutions to complex scientific problems, training neural networks, or racing to model fast-moving financial markets, you need a computing platform that provides the highest throughput and lowest latency possible. GPUs are widely recognized for providing the tremendous horsepower required by compute-intensive workloads. However, GPUs consume data much faster than CPUs and as the computing horsepower of GPU increases so does the demand for IO bandwidth.

Using GPUDirect, multiple GPUs, network adapters, solid-state drives (SSDs) and now NVMe drives can directly read and write CUDA host and device memory, eliminating unnecessary memory copies, dramatically lowering CPU overhead, and reducing latency, resulting in significant performance improvements in data transfer times for applications running on NVIDIA Tesla™ and Quadro™ products

索索要么无视，要么有以下理由：
1：并没有铺开，空有技术和实现没用。
2：“AMD已经用了类似的技术了啊，用在专业卡上” = 应用面太狭窄，不算铺开。
3：“PC上规划的技术多了，不铺开有什么可说的？”
4：“相似的东西多了，比如你能说我穿的衣服就是你的衣服吗？”

前3楼都疯了

光和影

不懂，什么意思？类似ps5的技术？

zk5856

这个和软软有什么关系？xsx用的是n卡？还是pc=xsx？不是很懂

光和影

如果是类似的技术，不正是说明ps5的方向是认可的方向么

真的是欺负坛友们看不懂英文。
