Efficiently adapting to sharing patterns in software DSMs

L.R. Monnerat, R. Bianchini
Proceedings 1998 Fourth International Symposium on High-Performance Computer Architecture  
In this paper we introduce a page-based Lazy Release Consistency protocol called ADSM that constantly and efficiently adapts to the applications' sharing patterns.  ...  Our main conclusions are that our categorization and adaptation strategies are useful techniques for improving the performance of page-based software DSMs, while ADSM is a highly-efficient option for low-cost  ...  Acknowledgements The authors would like to thank the adaptive TreadMarks group, in particular Cristiana Amza, for letting us borrow the implementation studied in this paper.  ...

Shared Memory in the Many-Core Age [chapter]

Stefan Nürnberger, Gabor Drescher, Randolf Rotta, Jörg Nolte, Wolfgang Schröder-Preikschat
2014 Lecture Notes in Computer Science  
With the evolution toward fast networks of many-core processors, the design assumptions at the basis of software-level distributed shared memory (DSM) systems change considerably.  ...  But efficient DSMs are needed because they can significantly simplify the implementation of complex distributed algorithms.  ...  The design of efficient software-level DSMs depends a lot on the underlying hardware's structure and the interface to the applications on top of the shared memory.  ...

Dynamic adaptation of sharing granularity in dsm systems

Ayal Itzkovitz, Nitzan Niv, Assaf Schuster
2000 Journal of Systems and Software  
One way to resolve the tradeoff is to dynamically adapt the granularity to the application memory access pattern.  ...  We show that applications may benefit from adapting the memory sharing to the memory access pattern, using both coarse grain sharing and fine grain sharing interchangeably in different stages of the computation  ...  Acknowledgments We are grateful to the anonymous referees, whose comments helped us improve the paper.  ...

Lazy Home-Based Protocol: Combining Homeless and Home-Based Distributed Shared Memory Protocols [chapter]

Byung-Hyun Yu, Paul Werstein, Martin Purvis, Stephen Cranefield
2005 Lecture Notes in Computer Science  
We present an in-depth analysis of the effects of the protocol on DSM applications.  ...  This paper presents our novel protocol design and implementation of an all-software page-based DSM system. The protocol combines the advantages of homeless and home-based protocols.  ...  There have been similar ideas of using the two coherence protocols selectively in order to implement a more efficient coherence protocol in a software DSM system.  ...

MP-LOCKs: replacing H/W synchronization primitives with message passing

Chen-Chi Kuo, J. Carter, R. Kuramkote
1999 Proceedings Fifth International Symposium on High-Performance Computer Architecture  
MP-LOCKs reduce the design complexity and runtime occupancy of DSM controllers and can exploit software's inherent flexibility to adapt to differing applications lock access patterns.  ...  We conclude that locks based on message passing should be considered as a replacement for hardware locks in future scalable multiprocessors that support efficient message passing mechanisms.  ...  We took great pains to conduct a fair comparison by including a detailed 4.4BSD-based kernel in our simulation environment to accurately simulate the software overhead of the proposed message passing mechanisms  ...

Merging the Publish-Subscribe Pattern with the Shared Memory Paradigm [chapter]

Loïc Cudennec
2018 Lecture Notes in Computer Science  
Both the publish-subscribe and the shared memory models offer such abstraction. However they are intended to be used in different application contexts.  ...  In this paper we propose to merge these two models into a new one.  ...  Software-Distributed Shared Memory (S-DSM) is used to federate distributed physical memory and provide a high level of abstraction to the application.  ...
