Hi,
  
  I am a newbie to R and trying to implement parallelism in R. I am currently using R-2.3.1, and Cygwin to run R on Windows xp.
  
  ssh and all are working fine,
  
  When I try to create a socket connection as
  
   makeSOCKcluster(c("localhost","localhost")), 
  
  it just waits for the other prcess on localhost to get created and respond. But this other process is not created.
  
  To debug, I put print statements in the "snow " file in library\snow\r  of R after every statement that comes under Socket Implementation. I  realized that it does the execution till
  
  system(a<-paste(rshcmd, "-l", user, machine, "env", env, script))
  
  part and then it goes in wait state. It cannot run the next command which is
  
  con <- socketConnection(port = port, server=TRUE, blocking=TRUE,
                               open="a+b")
  
  can someone please tell me what exactly could be the problem?
  
  Thank you,
  Rishi
