R Documentation

Starting snowFT Clusters

Description

Functions to start a snowFT cluster and to set default cluster options.

Usage

makeClusterFT(spec, type = getClusterOption("type"), ...)

Arguments

`spec`	Cluster specification.
`type`	Character string that specifies cluster type. Only `type="PVM"` supported.
`...`	Cluster option specifications.

Details

makeClusterFT starts a cluster of the specified or default type, loads the snowFT library on each node and returns a reference to the cluster. Only the cluster type "PVM" is supported in this version. The spec argument should be an integer specifying the number of slave nodes to create. See setDefaultClusterOptions() of the snow package for setting cluster options.

The cluster should be stopped by stopCluster of the snow package.

Note that on a snowFT cluster all snow functions can be applied, whereas on a cluster created by makeCluster of the snow package the snowFT functions will not work unless the snowFT library is loaded on all nodes.

Examples

  ## Not run: 
cl <- makeClusterFT(5)
res <- clusterApplyFT(cl, 1:10, get("+"), ...=3)
stopCluster(res[[2]])
print(res[[1]])
  
## End(Not run)
