Malleable tasks consist in considering the tasks of a parallel program as large computational units that may be themselves parallelized. In this paper we investigate the problem of scheduling a set of n independent malleable tasks on a m processors system, starting from the continuous version of the problem.
The problem of scheduling n tasks in a multiprocessor system with m processors to minimize the makespan is studied. Tasks are malleable, which means that a task can be executed by several processors at a time, its processing speed depends on the number of allocated processors, and a set of processors allocated to the same task can change over time. The processing speed of a task is a strictly increasing...
Celem poznawczym opracowania jest analiza możliwych implikacji wprowadzenia, zgodnie z wyrokiem Europejskiego Trybunału Sprawiedliwości (ETS) z dnia 1 marca 2011 roku w sprawie Test-Achats, zakazu różnicowania składki ubezpieczeniowej ze względu na płeć ubezpieczonego. W artykule postawiono tezę, że zakaz uwzględniania cechy płci w ubezpieczeniach gospodarczych, jest elementem niezgodnym z polityką...
Przedstawiono tutaj problem szeregowania n niezależnych zadań w systemie procesorów równoległych. Zadania są elastyczne, tj. zadanie może być wykonywane przez kilka procesorów jednocześnie oraz prędkość wykonywania zadania jest nieliniową funkcją od ilości procesorów przydzielonych do niego. Całkowita liczba procesorów w systemie wynosi m i jest to górna granica liczby procesorów, które mogą być używane...
In the paper, the problem of scheduling a set of n malleable tasks on m parallel computers is considered. The tasks may be executed by several processors simultaneously and the processing speed of a task is a function of the number of processors alloted. The problem is motivated by real-life applications of parallel computer systems in scientific computing of highly parallelizable tasks. Starting...
