\usage{
benchmark(obj, n = 10, expr = NULL, cores = NULL)
\method{plot}{parallelBenchmark}(x, type = "b", ..., show = c("speedup", "time"), legendpos = "topleft")
}
\arguments{
\item{obj}{Object from \code{MakeADFun}}
\item{n}{Number of replicates to obtain reliable results.}
\item{expr}{Optional expression to benchmark instead of default.}
\item{cores}{Optional vector of cores.}
\item{x}{Object to plot}
\item{type}{Plot type}
\item{...}{Further plot arguments}
\item{show}{Plot relative speedup or relative time?}
\item{legendpos}{Position of legend}
}
\description{
Benchmark parallel templates
Plot result of parallel benchmark
}
\details{
By default this function will perform timings of the most critical
parts of an AD model, specifically
\enumerate{
\item Objective function of evaluated template.
\item Gradient of evaluated template.
\item Sparse hessian of evaluated template.
\item Cholesky factorization of sparse hessian.
}
(for pure fixed effect models only the first two).
Expressions to time can be overwritten by the user (\code{expr}).
A \code{plot} method is available for Parallel benchmarks.
}
\examples{
\dontrun{
runExample("linreg_parallel",thisR=TRUE) ## Create obj
ben <- benchmark(obj,n=100,cores=1:4)
plot(ben)
ben <- benchmark(obj,n=10,cores=1:4,expr=expression(do.call("optim",obj)))
plot(ben)
}
