【问题描述】:
我的笔记本电脑有 4 核的 8GB RAM。
我的h2o版本如下,`
Package: h2o
Type: Package
Version: 3.10.0.8
Branch: rel-turing
Date: Mon Oct 10 13:47:51 PDT 2016
License: Apache License (== 2.0)
Depends: R (>= 2.13.0), RCurl, jsonlite, statmod, tools, methods, utils`
我初始化如下,
h2o.init(nthreads = -1,max_mem_size = "8g")
但是我得到的输出如下,
R is connected to the H2O cluster:
H2O cluster uptime: 13 hours 21 minutes
H2O cluster version: 3.10.0.8
H2O cluster version age: 21 days, 13 hours and 33 minutes
H2O cluster name: H2O_started_from_R_hp_ubq027
H2O cluster total nodes: 1
H2O cluster total memory: 1.33 GB
H2O cluster total cores: 4
H2O cluster allowed cores: 2
H2O cluster healthy: TRUE
H2O Connection ip: localhost
H2O Connection port: 54321
H2O Connection proxy: NA
R Version: R version 3.3.1 (2016-06-21)
为什么允许的内核只有 2 个,允许的内存只有 1.33gb,而几乎 8GB 可用?
