-#' * parallel = T means that an automatic parallelization of the likelihood via a standard R socket cluster is attempted, using the function \code{\link{generateParallelExecuter}}. By default, of the N cores detected on the computer, N-1 cores are requested. Alternatively, you can provide a integer number to parallel, specifying the cores reserved for the cluster. When the cluster is cluster is created, a copy of your workspace, including DLLs and objects are exported to the cluster workers. Because this can be very inefficient, you can explicitly specify the packages, objects and DLLs that are to be exported via parallelOptions. Using parallel = T requires that the function to be parallelized is well encapsulate, i.e. can run on a shared memory / shared hard disk machine in parallel without interfering with each other.

In this case, it is assumed that the likelihood is programmed such that it accepts a matrix with parameters as columns and the different model runs as rows. It is then up to the user if and how to parallelize this function. This option gives most flexibility to the user, in particular for complicated parallel architecture or shared memory problems.
