All jobs are executed sequentially using the current R process in which submitJobs is called. Thus, submitJob blocks the session until the job has finished. The main use of this ClusterFunctions implementation is to test and debug programs on a local computer.

Listing jobs returns an empty vector (as no jobs can be running when you call this) and killJob is not implemented for the same reasons.

makeClusterFunctionsInteractive(
  external = FALSE,
  write.logs = TRUE,
  fs.latency = 0
)

Arguments

external

[logical(1)]
If set to TRUE, jobs are started in a fresh R session instead of currently active but still waits for its termination. Default is FALSE.

write.logs

[logical(1)]
Sink the output to log files. Turning logging off can increase the speed of calculations but makes it very difficult to debug. Default is TRUE.

fs.latency

[numeric(1)]
Expected maximum latency of the file system, in seconds. Set to a positive number for network file systems like NFS which enables more robust (but also more expensive) mechanisms to access files and directories. Usually safe to set to 0 to disable the heuristic, e.g. if you are working on a local file system.

Value

[ClusterFunctions].
