Hi, I am trying to use 'snowfall' on a supercomputer SUSE Linux
shared-memory system.

However, I got this error message:

> library( snowfall )
Loading required package: snow
> sfInit(cpus=48,type='SOCK',parallel=T)
R Version:  R version 2.12.2 (2011-02-25)

snowfall 1.84 initialized (using snow 0.3-8): parallel execution on 48 CPUs.

>
> sfExportAll( )
TRUE,  :
  port 10187 cannot be opened
Error in sfInit(cpus = 48, type = "SOCK", parallel = T) :
  Starting of snow cluster failed! Error in socketConnection(port = port,
server = TRUE, blocking = TRUE,  :
  cannot open the connection
 Error in socketConnection(port = port, server = TRUE, blocking = TRUE,  :
  cannot open the connection
Execution halted


The system support MPI by using mpirun command but it has some other issues
about 'Rmpi' package. So I am wondering if I could just use 'SOCK' instead
of 'MPI'. Is that suitable for this environment? Or I can only use MPI
cluster on it?

Thanks,
Libo
