由于每台 Raspberry Pi 4B 计算机的CPU 上都有4个内核和 4GB RAM,这意味着我们的集群实际上总共有 12 个节点(每个 Pi 上 3x4),集群上有 12Gb(每个 Pi 上 3x4Gb)分布式 RAM 。 5.1主节点配置 编辑hosts文件以确保列出所有辅助节点: sudo vim /etc/hosts 添加以下内容(如果尚不存在): IP_ADDR_OF_NODE02...
To reduce thermal output when idling or under light load, the Pi4B reduces the CPU clock speed and voltage. During heavier load the speed and voltage (and hence thermal output) are increased. The internal governor will throttle back both the CPU speed and voltage to make sure th...
