Support for remote workers with fastRCluster ? #113

Closed ceresek closed 4 years ago

ceresek commented 5 years ago

Does fastRCluster support remote nodes ? I'm trying to do something like x <- makeFastRCluster (master = 'master', names = c ('worker')), but this fails because makeFastRCluster passes nnodes in place of names to psockClusterFactory and that causes later call to addClusterOptions to fail.

I'm asking mainly to know if I should fix this locally and experiment more, or if remote nodes are not supported for some other, more fundamental reason, which I would eventually run into.

This does look like an issue of makeFastRCluster. I am not aware of any reason why FastR couldn't work as a remote node, but we haven't tested that scenario yet.
