# NOT RUN {
# Initial configuration and execution

)
qsub_lapply(

  FUN = function(i) { Sys.sleep(1); i+1 },
  qsub_config = qsub_config
)

# Setting a default configuration and short hand notation for execution
set_default_qsub_config(qsub_config, permanent = T)
qsub_lapply(seq_len(3), function(i) { Sys.sleep(1); i+1 })

# Overriding a default qsub_config
qsub_lapply(seq_len(3), function(i) i + 1,
  qsub_config = override_qsub_config(name = "MyJob"))

# Don't wait for results, get a handle instead and retrieve later.
handle <- qsub_lapply(seq_len(3), function(i) i + 1,
  qsub_config = override_qsub_config(wait = F))

# Wait until results have been generated on the remote

# Retrieve results
