## Functions Providing Information on the doPar Backend

### Description

The `getDoParWorkers` function returns the number of execution workers there are in the currently registered doPar backend. It can be useful when determining how to split up the work to be executed in parallel. A `1` is returned by default.

The `getDoParRegistered` function returns TRUE if a doPar backend has been registered, otherwise FALSE.

The `getDoParName` function returns the name of the currently registered doPar backend. A `NULL` is returned if no backend is registered.

The `getDoParVersion` function returns the version of the currently registered doPar backend. A `NULL` is returned if no backend is registered.

### Usage

    getDoParWorkers()
    getDoParRegistered()
    getDoParName()
    getDoParVersion()

### Examples

    cat(sprintf('%s backend is registered\n',
                if(getDoParRegistered()) 'A' else 'No'))
    cat(sprintf('Running with %d worker(s)\n', getDoParWorkers()))
    (name <- getDoParName())
    (ver <- getDoParVersion())
    if (getDoParRegistered())
      cat(sprintf('Currently using %s [%s]\n', name, ver))
