We present an efficient and practical lock-free implementation of a garbage collection scheme based on reference counting aimed for the use with arbitrary lock-free dynamic data structures. The scheme guarantees the safety of local as well as global references, supports arbitrary memory reuse, uses atomic primitives which are available in modern computer systems and provides an upper bound on t...

Abstract. This chapter explores the stock price impact of expirations of lock-up provisions that prevent insiders from selling their shares after the Initial Public Offering (IPO). I examine 172 lock-up expirations of 142 IPOs floated on Germany’s Neuer Markt. I detect significant negative abnormal returns and a twenty-five percent increase in trading volume surrounding lock-up expiration. The ...

Der Vendor-Lock-in-Effekt bezeichnet die Abhängigkeit einer Investition von einem bestimmten Anbieter. Dieser kommt umso stärker zur Geltung, je länger die Nutzungsdauer der Investition (also z.B. die voraussichtliche Lebensdauer eines Softwaresystems) ist. Aus dem Vendor-Lock-in entstehen Risiken. Netzeffekte hingegen bezeichnen den Nutzen, den ein Anwender einer Technologie aus der Tatsache z...

This paper presents intelligent memory, a new memory architecture capable of providing e cient lock-free synchronization. In the intelligent memory, a sequence of operations on a shared object associated with that memory module can be processed without any intervention so that an environment for the synchronization can be provided by executing a critical section itself in that memory module. Fo...

The scalability of multithreaded applications on current multicore systems is hampered by the performance of lock algorithms, due to the costs of access contention and cache misses. In this paper, we propose a new lock algorithm, Remote Core Locking (RCL), that aims to improve the performance of critical sections in legacy applications on multicore architectures. The idea of RCL is to replace l...

In Canada, research has examined international-local student interaction by focusing on international students’ perceptions and experiences. As such, the perspectives of local students toward socialization with remain less explored. Designed as a survey-based case study 17 at university in Ontario, this sought to understand how improve between two groups. Additionally, investigated conceptualiz...
