Enable serial evaluation

Description

This class is used to parameterize serial evaluation, primarily to facilitate easy transition from parallel to serial code.

Usage

SerialParam(catch.errors = TRUE, stop.on.error = TRUE, log = FALSE,
    threshold = "INFO", logdir= NA_character_)

Arguments

Constructor

SerialParam(catch.errors = FALSE, log = FALSE, threshold = "INFO"):

Return an object to be used for serial evaluation of otherwise parallel functions such as bplapply, bpvec.

Methods

The following generics are implemented and perform as documented on the corresponding help page (e.g., ?bpworkers): bpworkers. bpisup, bpstart, bpstop, are implemented, but do not have any side-effects.

register for registering parameter classes for use in parallel evaluation.

Examples

p <- SerialParam()
simplify2array(bplapply(1:10, sqrt, BPPARAM=p))
bpvec(1:10, sqrt, BPPARAM=p)

## Not run: 
register(SerialParam(), default=TRUE)

## End(Not run)
