Organizational Transactive Memory Systems
European Psychologist, 2012The transactive memory system (TMS) concept has been extended from dyads and groups to organizations. While organizational TMS literature helps to understand how employees locate and utilize information based on their awareness of “who knows what” and “who knows who,” conceptual development is beneficial because TMS has been extended to organizations ...

The Design and Evaluation of P2P Transactive Memory System
2005 IEEE International Conference on e-Technology, e-Commerce and e-Service, 2005Transactive memory has been identified to describe a shared memory system for group members to store and access group intelligence. With the emerging peer-to-peer (P2P) technology, individuals within and between groups may interact by virtue of the peer-to-peer architecture to mobilize group dynamics.

A Compact Transactional Memory Multiprocessor System on FPGA
2010 International Conference on Field Programmable Logic and Applications, 2010In this paper we present a rapid prototyping platform on a single Field Programmable Gate Array (FPGA) with support for software transactional memory. The system is composed only by off-the-shelf cores and is useful for porting and early validation of programs to the transactional memory programming model.

Composition and transactive memory systems
Philosophical Explorations, 2015A recurrent theme in research on socially distributed cognition is to establish the claim that the cognitive phenomenon of transactive memory is grounded in a specific mode of organization: mechanistic compositional organization. My topic is the confluence of transactive remembering or transactive memory systems (TMSs) and mechanistic compositional ...

Removal of Conflicts in Hardware Transactional Memory Systems
International Journal of Parallel Programming, 2012This paper analyzes the sources of performance losses in hardware transactional memory and investigates techniques to reduce the losses. It dissects the root causes of data conflicts in hardware transactional memory systems (HTM) into four classes of conflicts: true sharing, false sharing, silent store, and write-write conflicts.

Interactive Transaction Processing for In-Memory Database System
2018In-memory transaction processing has gained fast development in recent years. Previous works usually assume the one-shot transaction model, where transactions are run as stored procedures. Though many systems have shown impressive throughputs in handling one-shot transactions, it is hard for developers to debug and maintain stored procedures. According

Organizing for Information Retrieval in Transactive Memory Systems
Communication Research, 2005Advancing transactive memory (TM) theory, this research explores information retrieval between members of 12 preexisting organizational work teams. The teams examined are larger than the ad hoc groups studied in previousTM research. The central components are team members' (a) communication for topic-specific information retrieval, (b) perceptions of ...

Proposing Software Transactional Memory for Embedded Systems
2011 Tenth International Symposium on Autonomous Decentralized Systems, 2011Processors have become multi-core, and transactional memory has been getting attention as a new concurrency control and coordination mechanism for shared data in this type of processor. Transactional memory is a memory management technology based on transactions used in the field of databases. An atomic action provided by transactional memory is a very

Proceedings of the 34th annual international symposium on Computer architecture, 2007
This paper quantifies the effect of architectural design decisions onthe performance of TxLinux. TxLinux is a Linux kernel modifiedto use transactions in place of locking primitives in several key subsystems.We run TxLinux on MetaTM, which is a new hardwaretransaction memory (HTM) model.MetaTM contains features that enable efficient and ...

Transactional event profiling in a best-effort hardware transactional memory system
Proceedings of the 21st international conference on Parallel architectures and compilation techniques, 2012Blue Gene/Q's (BG/Q) unique transactional memory system provides hardware isolation, atomicity and consistency for memory locations while leaving the details of the transactional programming system to software layers above the hardware [3]. This design allows for complex systems implemented as part of the software runtime. Here a profiling extension to
