近期横空出世的谷歌大模型Gemini3.0，在多个维度实现了关键突破，获得了多方赞誉！ 谷歌内部项目Apollo，在其数据中心大范围部署MEMS型OCS替换EPS，带来了数据中心网络架构的重大变革。从图表9可以看到，64个TPU芯 片形成一个cube，每个面有16条链路，每个块总共有96条光链路连接到OCSes。为了提供3D环面的环绕链路，这些链路上的对立的双方必须连 接到同一个OCS，因此，最外侧六个面上的TPU与48个OCSes相连（6×16÷2=48OCSes）。PalomarOCS为136×136规格（128个端口，外加8个用 于链路测试和维修的备用端口），内部的TPU之间通过电缆连接，从而实现4096个TPUv4芯片的预期总数，形成一个大型的超算系统。 Gemini3.0是真正的"原生多模态"模型。它能深度协同处理文字、图片、视频、音频等多种信息，并理解它们之间的关联。例如，它不仅能描 述一张图片，还能理解图片中的场景、动作和潜在含义。在权威的多模态基准测试中，其成绩处于领先地位。 目前全球主流OCS技术分为三大方向：MEMS方案、液晶方案(DLC)和直接光束偏转方案(DBS)，每种技术各有优劣，对 ...
