A batchtools backend that resolves futures sequentially in transient background R sessions

The batchtools local backend is useful for verifying parts of your batchtools setup locally, before using a more advanced backend such as the job-scheduler backends.

Usage

batchtools_local(...)

Arguments

...

Not used.

Details

Batchtools local futures use batchtools cluster functions created by batchtools::makeClusterFunctionsInteractive() with external = TRUE.

An alternative to the batchtools interactive backend is to use plan(future::cluster, workers = I(1)).

Examples

plan(batchtools_local)

message("Main process ID: ", Sys.getpid())
#> Main process ID: 258939

f <- future(Sys.getpid())
pid <- value(f)
message("Worker process ID: ", pid)
#> Worker process ID: 259240
