batchtools_template: Batchtools futures for LSF, OpenLava, SGE, Slurm, TORQUE etc.

Description

Batchtools futures for LSF, OpenLava, SGE, Slurm, TORQUE etc. are asynchronous multiprocess futures that will be evaluated on a compute cluster via a job scheduler.

Usage

batchtools_lsf(expr, envir = parent.frame(), substitute = TRUE,
  globals = TRUE, label = NULL, template = NULL, resources = list(),
  workers = Inf, ...)
batchtools_openlava(expr, envir = parent.frame(), substitute = TRUE,
  globals = TRUE, label = NULL, template = NULL, resources = list(),
  workers = Inf, ...)
batchtools_sge(expr, envir = parent.frame(), substitute = TRUE,
  globals = TRUE, label = NULL, template = NULL, resources = list(),
  workers = Inf, ...)
batchtools_slurm(expr, envir = parent.frame(), substitute = TRUE,
  globals = TRUE, label = NULL, template = NULL, resources = list(),
  workers = Inf, ...)
batchtools_torque(expr, envir = parent.frame(), substitute = TRUE,
  globals = TRUE, label = NULL, template = NULL, resources = list(),
  workers = Inf, ...)

Arguments

expr

The R expression to be evaluated

envir

The environment in which global environment should be located.

substitute

Controls whether expr should be substitute():d or not.

globals

(optional) a logical, a character vector, a named list, or a Globals object. If TRUE, globals are identified by code inspection based on expr and tweak searching from environment envir. If FALSE, no globals are used. If a character vector, then globals are identified by lookup based their names globals searching from environment envir. If a named list or a Globals object, the globals are used as is.

label

(optional) Label of the future (where applicable, becomes the job name for most job schedulers).

template

(optional) A batchtools template file or a template string (in brew format). If not specified, it is left to the batchtools package to locate such file using its search rules.

resources

A named list passed to the batchtools template (available as variable resources).

workers

(optional) The maximum number of workers the batchtools backend may use at any time. Interactive and "local" backends can only process one future at the time, whereas HPC backends where futures are resolved via separate jobs on a scheduler, the default is to assume an infinite number of workers.

…

Additional arguments passed to BatchtoolsFuture().

Value

An object of class BatchtoolsFuture.

Details

These type of batchtools futures rely on batchtools backends set up using the following batchtools functions:
