The two parameters α and β determine the shape and scale of the distribution, respectively. The mean and variance of the gamma distribution are respectively αβ and αβ 2 . Certain values of the parameters α and β relate the gamma distribution to other well-known distributions in probability theory and statistics [Allen 1990, Trivedi 2000].
Synchronizers and arbiters). It can lead to total failure at the system level. 2. Macroscopic metastability. This form of metastable behavior occurs in computer systems and computer networks. We brieﬂy review both forms of metastability. A more detailed discussion of metastability and its deeper consequences for computer performance can be found in Gunther [2000a, Part III]. 1 Microscopic Metastability All computer systems hardware requires clocking synchronization of some kind to handle interrupts, to perform bus arbitration, to initiate memory refreshes and so on.
