TLDR
It is argued that by identifying these assumptions explicitly, it is possible to reach a level of convergence in the space of job schedulers for parallel supercomputers by associating a suitable cost function with the execution of each job.Abstract:
The space of job schedulers for parallel supercomputers is rather fragmented, because different researchers tend to make different assumptions about the goals of the scheduler, the information that is available about the workload, and the operations that the scheduler may perform. We argue that by identifying these assumptions explicitly, it is possible to reach a level of convergence. For example, it is possible to unite most of the different assumptions into a common framework by associating a suitable cost function with the execution of each job. The cost function reflects knowledge about the job and the degree to which it fits the goals of the system. Given such cost functions, scheduling is done to maximize the system's profit.read more

Theory and Practice in Parallel Job Scheduling
TL;DR: The scheduling of jobs on parallel supercomputer is becoming the subject of much research, however, there is concern about the divergence of theory and practice, and a proposal for standard interfaces among the components of a scheduling system is proposed.

The workload on parallel supercomputers: modeling the characteristics of rigid jobs
Uri Lublin,Dror G. Feitelson +1 more
TL;DR: This work analyzes and model the job-level workloads with an emphasis on those aspects that are universal to all sites, and creates a synthetic workload based on the results of the analysis.

Design and Evaluation of Job Scheduling Strategies for Grid Computing
TL;DR: Simulations were used to evaluate typical scheduling structures that occur in computational grids and FCFS proves to perform better than Backfill when using a central job-pool.

Workload Modeling for Computer Systems Performance Evaluation
TL;DR: Using this book, readers will be able to analyze collected workload data and clean it if necessary, derive statistical models that include skewed marginal distributions and correlations, and consider the need for generative models and feedback from the system.

Scheduler activations: effective kernel support for the user-level management of parallelism
TL;DR: It is argued that the performance of kernel threads is inherently worse than that of user-level threads, rather than this being an artifact of existing implementations, and that managing parallelism at the user level is essential to high-performance parallel computing.
