R+H20: Can you increase cluster total memory?

[Jared Wolf]

Hello,

I'm running H2O through R on a desktop with 8gb (6gb free). Upon initialization, H2O only has a total cluster memory of 1.76gb. How can I increase this?

Thanks,

Jared

You have to shutdown the cluster, then call init() again, but specify
the memory to use. E.g.

h2o.init(nthreads=-1, max_mem_size="4g")

(to use all cores, and use 4GB of your 6GB)
