Dear All
I have sucessfully created cluster of four nodes using localhost in my local
machine by executing the following command
> cl<-makePSOCKcluster(c(rep("localhost",4)),outfile='',homogeneous=FALSE,port=11001)
starting worker pid=4271 on localhost:11001 at 12:12:26.164
starting worker pid=4280 on localhost:11001 at 12:12:26.309
starting worker pid=4289 on localhost:11001 at 12:12:26.456
starting worker pid=4298 on localhost:11001 at 12:12:26.604
>
> stopCluster(cl)
Now I am trying to create a cluster of 2 nodes (one in my local machine and
another remote machine) by using "makePSOCKcluster" command. Both machine have
identical settings and connected by SSH. OS is Ubuntu 14.04 LTS & R version
3.2.1. I have executed the follwoing command to create cluster but getting the
following error message and R Session is getting hanged.
cl<-makePSOCKcluster(c(rep("soumen@10.10.2.32",1)),outfile='',homogeneous=FALSE,port=11001)
soumen@10.10.2.32's password:
