我们在 AWS 中将 h2o 作为单节点集群运行:R is connected to the H2O cluster: H2O cluster uptime: 5 seconds 217 milliseconds H2O cluster timezone: Etc/UTC H2O data parsing timezone: UTC H2O cluster version: 3.17.0.4153 H2O cluster version age: 10 months and 4 days !!! H2O cluster name: h2o-8ba55ebb-7d49-41bd-b4e2-d7be45b5f53e H2O cluster total nodes: 1 H2O cluster total memory: 22.20 GB H2O cluster total cores: 8 H2O cluster allowed cores: 8 H2O cluster healthy: TRUE H2O Connection ip: localhost H2O Connection port: 54321 H2O Connection proxy: NA H2O Internal Security: FALSE H2O API Extensions: XGBoost, Algos, AutoML, Core V3, Core V4 R Version: R version 3.4.3 (2017-11-30) 并使用 nthreads -1 从 java 启动 h2o:java -ea -Xmx25g -jar /path/to/h2o.jar -name unique-cloud-name -ip localhost -ice_root /tmp/h2o-tmp -nthreads -1我们想知道 h2o 是否在单节点集群中进行并行处理/使用所有可用和允许的内核。当我们在命令行中执行 top -H 时,我们确实看到了 8 个活动的 java 进程,并想知道它们是否来自 h2o 并帮助生成我们的模型。
