Vol: 4(4) No: 1 / March 1994 A Decentralized Scheduler: an Object-Oriented Approach Cristian D. Ionitoiu Facultatea de Calculatoare si Automatica, Universitatea Tehnica Timisoara, V. Parvan nr. 2, 1900 Timisoara, Romania, e-mail: cristi@utt.ro Keywords: scheduler, operating systems Abstract This paper presents an application of the theory of processes in the operating systems field. In the first part (sections 1,2,3) some theoretical notions about concurrency are shortly presented, the concept of a decentralized scheduler is described and the part ends with the equations governing the scheduler operation. The second part (sections 4,5,6) contains the implementation details of the theory, using the OOP paradigm under the UNIX operating system. References [1] J. K. M. Baeten, W. P.
