Scalable Parallel Application Launch on CplantTM

چکیده
This paper describes the components of a runtime system for launching parallel applications and presents performance results for starting a job on more than a thousand nodes of a workstation cluster. This runtime system was developed at Sandia National Laboratories as part of the Computational Plant (Cplant) project, which is deploying large-scale parallel computing clusters using commodity hardware and the Linux operating system. We have designed and implemented a flexible runtime system that allows for launching parallel jobs on thousands of nodes in a matter of seconds. The interactions of the components are described, and the key issues that address the scalability and performance of the runtime system are discussed. We also present performance results of launching executables of varying sizes on more than a thousand nodes.

Multi-objective and Scalable Heuristic Algorithm for Workflow Task Scheduling in Utility Grids
To use services transparently in a distributed environment, the Utility Grids develop a cyber-infrastructure. The parameters of the Quality of Service such as the allocation-cost and makespan have to be dealt with in order to schedule workflow application tasks in the Utility Grids. Optimization of both target parameters above is a challenge in a distributed environment and may conflict one an...
متن کاملScalable Runtime for MPI: Efficiently Building the Communication Infrastructure
The runtime environment of MPI implementations plays a key role to launch the application, to provide out-of-band communications, enabling I/O forwarding and bootstrapping of the connections of high-speed networks, and to control the correct termination of the parallel application. In order to enable all these roles on a exascale parallel machine, which features hundreds of thousands of computi...

متن کاملOn the Appropriateness of Commodity Operating Systems for Large-Scale, Balanced Computing Systems
In the past five years, we have been involved in the design and development of Cplanttm. An important goal was to take advantages of commodity approaches wherever possible. In particular, we selected Linux, a commonly available operating system, for the compute nodes of Cplanttm. While the use of commodity solutions, including Linux, was critical to the success of Cplanttm, we believe that such...
