Attacking the process migration bottleneck

by Edward R. Zayas - In Proceedings of the Eleventh ACM Symposium on Operating Systems Principles , 1987
"... Moving the contents of a large virtual address space stands out as the bottleneck in process migration, dominating all other costs and growing with the size of the program. Copy-on-reference shipment is shown to successfully attack this problem in the Accent distributed computing environment. Logica ..."

Spectral Analysis of Bottleneck Traffic

by Xinming He, Christos Papadopoulos, John Heidemann, Urbashi Mitra, Usman Riaz, Alefiya Hussain
"... Abstract — Internet traffic contains a rich set of periodic patterns imposed by various processes. Examples include backto-back packet transmissions on bottleneck links, periodic routing information exchange, transport layer effects such as TCP windowing behavior, and application layer effects such ..."

Cheating the I/O Bottleneck: Network Storage with Trapeze/Myrinet

by Darrell C. Anderson , Jeffrey S. Chase, Syam Gadde, Andrew J. Gallatin, Kenneth G. Yocum, Michael J. Feeley - IN PROCEEDINGS OF THE 1998 USENIX TECHNICAL CONFERENCE , 1998
"... Recent advances in I/O bus structures (e.g., PCI), highspeed networks, and fast, cheap disks have significantly expanded the I/O capacity of desktop-class systems. This paper describes a messaging system designed to deliver the potential of these advances for network storage systems including cluste ..."

memory system. The paper focuses on support for zero-copy page migration in GMS/Trapeze using two RPC variants important for peer-peer distributed services: (1) delegated RPC in which a request is delegated to a third party, and (2) nonblocking RPC in which replies are processed from the Trapeze receive

Migration bottlenecks, climate, and the conservation of Pleistocene relicts in central Asia

by Joel Berger, Kim Murray Berger, Scott Bergen, Bayarbaatar Buuveibaatar, Amanda Fine, Badamjav Lkhagvasuren, Julie K. Young, Peter Zahler - Open Cons Biol J , 2008
"... Abstract: Land bridges once assured transcontinental connectivity, but climate-induced habitat loss resulted in the extinc-tion of numerous North American large mammals. Using GPS technology on the formerly widespread but now endan-gered saiga in Mongolia, we identified a fine-scaled 5-km wide criti ..."

The world’s great overland migrations are disappearing, truncating fundamental processes that have contributed to ecosystem functioning for millennia.

Proactive Process-Level Live Migration and Back Migration in HPC Environments

by Chao Wang, Frank Mueller, Christian Engelmann, Stephen L. Scott
"... As the number of nodes in high-performance computing environments keeps increasing, faults are becoming common place. Reactive fault tolerance (FT) often does not scale due to massive I/O requirements and relies on manual job resubmission. This work complements reactive with proactive FT at the proc ..."

at the process level. Through health monitoring, a subset of node failures can be anticipated when one’s health deteriorates. A novel process-level live migration mechanism supports continued execution of applications during much of processes migration. This scheme is integrated into an MPI execution environment

Energetic bottlenecks and other design constraints in avian annual cycles

by Theunis Piersma - Integrative and Comparative Biology , 2002
"... SYNOPSIS. The flexible phenotypes of birds and mammals often appear to represent adjustments to alleviate some energetic bottleneck or another. By increasing the size of the organs involved in digestion and assim-ilation of nutrients (gut and liver), an individual bird can increase its ability to pr ..."

Arctic tundra (probably mainly a function of costs of thermoregulation) and during winter in temperate coastal wetlands (a function of the high costs of processing mollusks, prey poor in nutrients but rich in shell material and salt water). During migration, red knots phenotypically alternate between a

Security for Mobile Agents: Authentication and State Appraisal

by William M. Farmer, Joshua D. Guttmann, Vipin Swarup - In Proceedings of the European Symposium on Research in Computer Security (ESORICS , 1996
"... . Mobile agents are processes which can autonomously migrate to new hosts. Despite its many practical benets, mobile agent technology results in signicant new security threats from malicious agents and hosts. The primary added complication is that, as an agent traverses multiple hosts that are t ..."

(Article begins on next page) The Knowledge-Remixing Bottleneck

by Groth P. T, Paul Groth
"... Traditionally, the knowledge-acquisition bottleneck has been a core problem in intelligent systems. How do we get information into an intelligent system so that it can reason and operate over it? Over the past five to ten years, we’ve seen how the Web has been central to attacking this problem: for ..."

A simple process for migrating server applications to SMP:s

by Daniel Häggander, Lars Lundberg , 2001
"... A strong focus on quality attributes such as maintainability and flexibilityhas resulted in a number of new methodologies, e.g., object-oriented and component-based design, which can significantly limit the application performance. A major challenge is to find solutions that balance and optimize the ..."

demanding with respect to performance due to real-time requirements on throughput and response time. SMP:s and multithreading are used in order to give these applications a high and scalable performance. Our main finding is that dynamic memory management is a major bottleneck in these types of applications

Data and Process Migration in the Aries Decentralized Abstract Machine (ADAM)

by Andrew Huang
"... The Problem: Access latency to memory is a performance bottleneck for contemporary computer systems. The partitioning of computers into separate memory and processor components has become a bottleneck simply due to the distance signals have to travel between these components. Figure 1 [1] illustrate ..."
