A utility function that aims to streamline the set up
of the required future backend with sensible defaults for most users of
regional_epinow
. More advanced users are recommended to setup their own
future
backend based on their available resources.
Usage
setup_future(
reported_cases,
strategies = c("multisession", "multisession"),
min_cores_per_worker = 4
)
Arguments
- reported_cases
A data frame of confirmed cases (confirm) by date (date), and region (
region
).- strategies
A vector length 1 to 2 of strategies to pass to
future::plan
. Nesting of parallelisation is from the top level down. The default is to set up nesting parallelisation with both usingfuture::multisession
(future::multicore
will likely be a faster option on supported platforms). For single level parallelisation use a single strategy orfuture::plan
directly. See?future::plan
for options.- min_cores_per_worker
Numeric, the minimum number of cores per worker. Defaults to 4 which assumes 4 MCMC chains are in use per region.
