Good day,

I couldn't get a working param object. It never completes the command 

param = bpstart(SnowParam(2, manager.hostname = "144.130.152.1", manager.port = 
2559))

I obtained the IP address by typing "My IP address" into Google and it gave me 
the address shown. I used netstat -an and 

  Proto  Local Address          Foreign Address        State
  TCP    127.0.0.1:2559         0.0.0.0:0              LISTENING

was one of the results displayed. I have reproduced this problem on another 
computer with Windows 10. I also tried

param = bpstart(SnowParam(2, manager.hostname = "127.0.0.1", manager.port = 
2559)) but it doesn't complete.

I was able to identify the problem is with the line

bpbackend(x) <- do.call(parallel::makeCluster, cargs)

So, to summarise,

> cargs
$`spec`
[1] 2

$type
[1] "SOCK"

$snowlib
[1] "C:/Program Files/R/R-3.5.0/library/BiocParallel"

$master
[1] "127.0.0.1"

$port
[1] 2559

> do.call(parallel::makeCluster, cargs) # Freezes.

Should I ask the question on R-devel because it doesn't appear to be specific 
to Bioconductor ?
