An Extensible Interpreter Framework for Software Transactional Memory
"... Abstract: Software transactional memory (STM) is a new approach for coordinating concurrent threads, for which many different implementation strategies are currently being researched. In this paper we show that if a language implementation provides reflective access to explicit memory locations, it ..."

Dealing with disaster: Surviving misbehaved kernel extensions
- In OSDI
, 1996
"... Today’s extensible operating systems allow applications to modify kernel behavior by providing mechanisms for application code to run in the kernel address space. The advantage of this approach is that it provides improved application flexibility and performance; the disadvantage is that buggy or ma ..."

hoarding, that can arise when application code is introduced into the kernel. In this paper, we present an analysis of extension mechanisms in the VINO kernel. VINO uses software fault isolation as its safety mechanism and a lightweight transaction system to cope with resource-hoarding. We explain how
A flexible framework for implementing software transactional memory
- In ACM Conference on Object-Oriented Programming, Systems, Languages, and Applications
, 2006
"... We describe DSTM2, a Java TM software library that provides a flexible framework for implementing object-based software transactional memory (STM). The library uses transactional factories to transform sequential (unsynchronized) classes into atomic (transactionally synchronized) ones, providing a s ..."

Compiler and Runtime Support for Efficient Software Transactional Memory
, 2006
"... Programmers have traditionally used locks to synchronize concurrent access to shared data. Lock-based synchronization, however, has well-known pitfalls: using locks for fine-grain synchronization and composing code that already uses locks are both difficult and prone to deadlock. Transactional memor ..."

memory provides an alternate concurrency control mechanism that avoids these pitfalls and significantly eases concurrent programming. Transactional memory language constructs have recently been proposed as extensions to existing languages or included in new concurrent language specifications, opening
Dynamic Performance Tuning of Word-Based Software Transactional Memory
"... The current generation of software transactional memories has the advantage of being simple and efficient. Nevertheless, there are several parameters that affect the performance of a transactional memory, for example the locality of the application and the cache line size of the processor. In this p ..."

. In this paper, we investigate dynamic tuning mechanisms on a new time-based software transactional memory implementation. We study in extensive measurements the performance of our implementation and exhibit the benefits of dynamic tuning. We compare our results with TL2, which is currently one of the fastest
A Theory of Networks for Approximation and Learning
- Laboratory, Massachusetts Institute of Technology
, 1989
"... Learning an input-output mapping from a set of examples, of the type that many neural networks have been constructed to perform, can be regarded as synthesizing an approximation of a multi-dimensional function, that is solving the problem of hypersurface reconstruction. From this point of view, t ..."

A hardware/software framework for supporting transactional memory in a mpsoc environment
- SIGARCH Comput. Archit. News
"... Manufacturers are focusing on multiprocessorsystem-on-a-chip (MPSoC) architectures in order to provide increased concurrency, rather than increased clock speed, for both large-scale as well as embedded systems. Traditionally lock-based synchronization is provided to support concurrency; however, man ..."

, managing locks can be very difficult and error prone. In addition, the performance and power cost of lock-based synchronization can be high. Transactional memories have been extensively investigated as an alternative to lock-based synchronization in general-purpose systems. It has been shown
Extensible Transactional Memory Testbed
, 2009
"... Transactional Memory (TM) is a promising abstraction as it hides all synchronization complexities from the programmers of concurrent applications. More particularly the TM paradigm operated a complexity shift from the application programming to the TM programming. Therefore, expert programmers have ..."
