Seed generation for pseudorandom number generation
For many of the functions in
Random, if no seed is provided by the
user, one is chosen based on the current time in microseconds, allowing
for some degree of variability in seed selection. The intent of
SeedGenerator is to provide a menu of other options for
initializing the random stream seed, but few options are implemented
at present. In particular, it would be useful to allow multiple tasks to
create different seeds at the same time, or to allow different
functions running at the same time to produce different seeds.
- record SeedGenerator¶
Provides methods to help generate seeds when the user doesn’t want to create one. It currently supports two type methods. Both start with the current time.
- proc type currentTime: int(64)¶
Generate a seed based on the current time in microseconds as reported by
Time.getCurrentTime. This seed is not suitable for the NPB RNG since that requires an odd seed.
