\title{Create or query current context}
\description{
   These  functions query or establish a context for the computations on
   a GPU. 
}
\usage{
createContext(flags = 0L, device = 1L)
cuGetContext(create = TRUE, ..., asContext = TRUE)
}
\arguments{
  \item{flags}{an integer vector specifying the configuration options
    for creating the context.}
  \item{device}{the identity of the device for which to create the context.}
  \item{create}{a logical value that controls whether we create a context
    if none is established.}
  \item{\dots}{additional arguments passed to \code{createContext}}
  \item{asContext}{a logical value currently ignored.}
}
\value{
  Both functions return an object of class \code{CUcontext}.
