| This process is also a ''W''-bit source, except the values produced are taken from a file. The identified ''ID'' is used to determine the file name, and the file is assumed to have at least one data value. By default, the file name is ''_infile_.{ID}''. The file format is a sequence of hexadecimal values, one per line. If ''LOOP'' is set to true, then the sequence of values specified in the file is repeated forever. | This process is also a ''W''-bit source, except the values produced are taken from a file.

| The ''sim::rand'' namespace contains support for random number generation, and includes the definition of a random source. | The ''sim::rand'' namespace contains support for random number generation, and includes the definition of a number of processes that use this random number generation functionality. The underlying random number generator used is a pseudo-random number generator, and hence the sequence of "random" numbers is deterministic. To ensure that these numbers remain unchanged on different platforms, we use a local mirror of the ''rand_r'' function from glibc. |
