We study efficient deterministic parallel algorithms on two models: restartable fail-stop CRCW PRAMs and asynchronous PRAMs. In the first model, synchronous processes are subject to arbitrary stop failures and restarts determined by an on-line adversary and involving loss of private but not shared m

Abstract
This paper deals with the sequencing problem of minimizing linear delay costs with parallel identical processors. The theoretical properties of this mβmachine problem are explored, and the problem of determining an optimum scheduling procedure is examined. Properties of the optimum schedule are given as well as the corresponding reductions in the number of schedules that must be evaluated in the search for an optimum. An experimental comparison of scheduling rules is reported; this indicates that although a class of effective heuristics can be identified, their relative behavior is difficult to characterize.

We show that the problem of scheduling chains of unit execution time (UET) jobs on uniform processors with communication delays to minimize makespan is NP-hard in the strong sense. We also give a heuristic that generates solutions with known, and relatively small, absolute error for this problem. Th
