Hi Tolga,
in SNOW you have to start a cluster with the command
> library(snow)
> cluster <- makeCluster(#nodes)
The object "cluster" is a list with an object for each node and each
object again is a list with all informations (rank, comm, tags)
The size of the cluster is the length of the list.
> #nodes == length(cluster)
E.g. the rank for node one you can get by
> cluster[[1]]$rank
Best

Dear R Users,
I am attempting to use the snow package for clustering. Is there a way to
identfy, in the environment of each node, a rank for that node and also,
the total size of the cluster ?
By way of analogy, I am looking for the functions in snow equivalent to
mpi.comm.rank() and mpi.comm.size() from RMPI, in case that makes things
clearer.
Thanks in advance,
Tolga
