Re: [R] cluster/snow question
Hi Tolga,
I am not sure why ls() is showing only "args" and "fun".
But x is at the nodes. Try this:

Dear R Users,
Apologies for a somewhat basic cluster question. I am trying to come to
grips with how variables are instantiated within the environment of each
node in a cluster. When I run the following code, I expect to see the
variable "x" in the environment of each node, but fail to do so. W

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 lis
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
