Looks like I was sloppy and didn't clean up after myself in previous
session(s). I'm trying to activate my cores via doSMP package like so:

> wrk <- startWorkers(4, FORCE = TRUE)  # if I don't use FORCE, it won't
create the object
Warning messages:
1: In startWorkers(4, FORCE = TRUE) :
  there is an existing doSMP session using doSMP1
2: In startWorkers(4, FORCE = TRUE) :
  there is an existing doSMP session using doSMP2
3: In startWorkers(4, FORCE = TRUE) :
  there is an existing doSMP session using doSMP3
4: In startWorkers(4, FORCE = TRUE) :
  there is an existing doSMP session using doSMP4
5: In startWorkers(4, FORCE = TRUE) :
  there is an existing doSMP session using doSMP5
6: In startWorkers(4, FORCE = TRUE) :
  there is an existing doSMP session using doSMP6
7: In startWorkers(4, FORCE = TRUE) :
  there is an existing doSMP session using doSMP7
8: In startWorkers(4, FORCE = TRUE) :
  there is an existing doSMP session using doSMP8
9: In startWorkers(4, FORCE = TRUE) : unable to recreate task queue doSMP1
> registerDoSMP(wrk)

After I registerDoSMP, I get two popup windows that my Rterm has stopped
responding. If I try to run something in parallel, only one/two cores will
work. Because I failed to stop workers in my previous sessions (and have
rebooted the system inbetween), I don't have objects with which I could
stopWorkers(obj). I tried stopWorkers(wrk) (after using FORCE in
startWorkers), but R session seems to hang (console unresponsive and not
much is going with CPU usage. How can I "reboot" cores so that I'll be able
to register workers?


Cheers,
Roman
