NVLink 是一种 GPU 之间的直接互连,双向互连速度达 1.8 TB/s,可扩展服务器内的多 GPU 输入/输出 (IO)。NVIDIA NVLink 交换机 ASIC 可连接多个 NVLink,实现在单个机架内和多个机架间以 NVLink 能够达到的最高速度进行多对多 GPU 通信。 为了支持高速集合运算,每个 NVLink 交换机都配有 NVIDIA SHARP™ 技...
第三代 NVIDIA NVSwitch 旨在为 NVLink交换机系统提供节点内或节点外部 GPU 的连接。它还将硬件加速与多播和 NVIDIA 可扩展分层聚合和缩减协议( SHARP ) 在网络缩减中。 NVIDIA NVSwitch 也是 NVLink 开关 网络设备 ,允许创建最多连接 256 个的群集 NVIDIA H100TensorCore GPUs 以及 57.6TB / s 的全对全带宽。
SHARP 是网络计算功能，最初在 NVIDIA Quantum InfiniBand 网络上使用。它可以使通信密集型 AI 应用的数...
英伟达收购的Mellanox在InfiniBand领域也处于佼佼者。自收购Mellanox以来,NVIDIA也开始将NVLink技术与InfiniBand(IB)技术相结合,推出新一代NVSwitch芯片和具有SHARP功能的交换机,针对外部GPU服务器网络进行了优化。 InfiniBand是一种开放标准的网络互连技术,具有高带宽、低延迟、高可靠性的特点。该技术由 IBTA(InfiniBand 贸易...
工艺,而且引用了sharp的加速,所以说整体来说呢,也就是合金为止,英伟达最能打的一款小型片框的一个小模组,而带宽呢,我们刚才讲的也是确实非常的惊人,GPU到GPU之间呢能够到达900GB每秒,那现在呢,最后我们看一下整个的block,刚才讲到了就加入了新的shop的模块,可以并行的去管理更多主shop,那对应的就是我们逻辑电路里...
