Good morning, I was using the packages snow 0.3-3 and snowfall 1.84 with R.10.1 : it is working great ! (Windows 7)
Since I have tried to update my R version (Windows 7). I cannot make the packages snow and snowfall works for parallel processing. I have tried the following version combinations: Snowfall 1.84 & snow 0.3-5 with R version 2.12.1 / 2.12.2 / 2.13.0 Snowfall 1.84 & snow 0.3-3 with R version 2.13.0 With the following code Library(snow) Library(snowfall) sfInit(parallel=TRUE, cpus=7) and the system is hanging ... R-2.13.0 has been installed in folder C:/R/R.-2.13.0 (and not in folder c:/Program Files or C:/Programme on this computer) --> no symbolic link or blank space issue in path name. I have tried the code "Sock.r" (posted on the 16 May 2011 on this list by Uwe Ligges, although my guess is that it has been integrated in the version 0.3-5 of snow ...). Without success. On the command line (i.e. without RGui), trying first sfInit() (works fine ) and sfInit(parallel=TRUE, cpus=7), I got the following error message ... (R-2.13.0) > sfInit() snowfall 1.84 initialized: sequential execution, one CPU. > sfStop() > sfInit(parallel=TRUE,cpus=7) Error in socketConnection(port = port, server = TRUE, blocking = TRUE, cannot open the connection In addition: Warning message: In socketConnection(port = port, server = TRUE, blocking = TRUE, : port 10187 cannot be opened Error in sfInit(parallel = TRUE, cpus = 7) : Starting of snow cluster failed! Error in socketConnection(port = po , : cannot open the connection Error in socketConnection(port = port, server = TRUE, blocking = TRUE cannot open the connection Any suggestions ?
