Dear All,
At least in three different GNU/Linux systems, the parallel function
from the multicore package leaves defunct (zombie) R processes.
For instance
library(multicore)
parallel(1:5)
collect()
After collect, the child process (with pid as given by collect) is
left defunct. (If we run the last two lines of code again, the
previously defunct process will be replaced by the new defunct
process).
Is this to be expected? The documentation for 'collect' says it
collects results from parallel processes (and I thought it also read
the exit status of the child).
Best,
R.
