Multithreading Design Patterns and Thread-Safe Data Structures
Lecture 12: Multithreading Design Patterns and Thread-Safe Data Structures Principles of Computer Systems Autumn 2019 Stanford University Computer Science Department Lecturer: Chris Gregg Philip Levis PDF of this presentation 1 Review from Last Week We now have three distinct ways to coordinate between threads: mutex: mutual exclusion (lock), used to enforce critical sections and atomicity condition_variable: way for threads to coordinate and signal when a variable has changed (integrates a lock for the variable) semaphore: a generalization of a lock, where there can be n threads operating in parallel (a lock is a semaphore with n=1) 2 Mutual Exclusion (mutex) A mutex is a simple lock that is shared between threads, used to protect critical regions of code or shared data structures. mutex m; mutex.lock() mutex.unlock() A mutex is often called a lock: the terms are mostly interchangeable When a thread attempts to lock a mutex: Currently unlocked: the thread takes the lock, and continues executing Currently locked: the thread blocks until the lock is released by the current lock- holder, at which point it attempts to take the lock again (and could compete with other waiting threads). Only the current lock-holder is allowed to unlock a mutex Deadlock can occur when threads form a circular wait on mutexes (e.g. dining philosophers) Places we've seen an operating system use mutexes for us: All file system operation (what if two programs try to write at the same time? create the same file?) Process table (what if two programs call fork() at the same time?) 3 lock_guard<mutex> The lock_guard<mutex> is very simple: it obtains the lock in its constructor, and releases the lock in its destructor. -

Lock Free Data Structures Using STM in Haskell
Lock Free Data Structures using STM in Haskell Anthony Discolo1, Tim Harris2, Simon Marlow2, Simon Peyton Jones2, Satnam Singh1 1 Microsoft, One Microsoft Way, Redmond, WA 98052, USA {adiscolo, satnams}@microsoft.com http://www.research.microsoft.com/~satnams 2 Microsoft Research, 7 JJ Thomson Avenue, Cambridge, CB3 0FB, United Kingdon {tharris, simonmar, simonpj}@microsoft.com Abstract. This paper explores the feasibility of re-expressing concurrent algo- rithms with explicit locks in terms of lock free code written using Haskell’s im- plementation of software transactional memory. Experimental results are pre- sented which show that for multi-processor systems the simpler lock free im- plementations offer superior performance when compared to their correspond- ing lock based implementations. 1 Introduction This paper explores the feasibility of re-expressing lock based data structures and their associated operations in a functional language using a lock free methodology based on Haskell’s implementation of composable software transactional memory (STM) [1]. Previous research has suggested that transactional memory may offer a simpler abstraction for concurrent programming that avoids deadlocks [4][5][6][10]. Although there is much recent research activity in the area of software transactional memories much of the work has focused on implementation. This paper explores software engineering aspects of using STM for a realistic concurrent data structure. Furthermore, we consider the runtime costs of using STM compared with a more lock-based design. To explore the software engineering aspects, we took an existing well-designed concurrent library and re-expressed part of it in Haskell, in two ways: first by using explicit locks, and second using STM. -
Danske Bank A/S
DANSKE BANK A/S AGM ON 18 MARCH 2019 - 10 REASONS TO VOTE FOR AN INDEPENDENT INVESTIGATION Danske Bank A/S 10 reasons to vote for an independent investigation On 4 February 2019, Deminor submitted a motion to have an independent investigator appointed by the shareholders at Danske Bank’s AGM on 18 March 2019. This motion is item 12 on the agenda of the AGM. The purpose of this independent investigation is to ensure that shareholders become aware of the identity of the persons who allowed vast sums of money to be laundered through Danske Bank over the years. Those ultimately responsible at the bank should be identified and held to account. Danske Bank has indicated in the response to the motion that it “does not believe that any further investigations are required” because the Danish law firm Bruun & Hjejle already investigated the matter sufficiently. This reply does little to solve the issue that the report was biased i.a. because the Danish law firm admitted in its very own words that it was “neither impartial nor independent”. See item 3 below for further explanation. 2 Danske Bank A/S 10 reasons to vote for an independent investigation We invite you to support this motion for these 10 key reasons: 1. Money laundering is not a victimless crime. Money laundering is a financial transaction scheme that aims to conceal the identity, source, and destination of illicitly-obtained money 1. In other words, it is the process of making illegal- ly-gained proceeds (i.e., “dirty money”) appear legal (i.e., “clean”) 2. -
Status Review on Implementation of TSO and DSO Unbundling Provisions
Legal Affairs Committee Implementation of TSO and DSO Unbundling Provisions – Update and Clean Energy Package Outlook CEER Status Review Ref: C18-LAC-02-08 14 June 2019 Council of European Energy Regulators asbl Cours Saint-Michel 30a, Box F – 1040 Brussels, Belgium Arrondissement judiciaire de Bruxelles – RPM 0861.035.445 Ref: C18-LAC-02-08 CEER Status Review on TSO and DSO Unbundling INFORMATION PAGE Abstract This CEER document (C18-LAC-02-08) presents an updated Status Review on the Implementation of Transmission and Distribution System Operators’ Unbundling Provisions of the 3rd Energy Package, focusing on new developments since summer 2015. It also briefly summarises the main changes and novelties with regard to unbundling-related provisions that were made in the recasts of the Electricity Directive and Electricity Regulation within the framework of “Clean Energy for All Europeans” package (CEP). Under the 3rd Energy Package, energy networks are subject to unbundling requirements which oblige Member States to ensure the separation of vertically integrated energy companies, resulting in the separation of the various stages of energy supply (generation, transmission, distribution, and retail). This Status Review aims to assess the status of DSO and TSO unbundling, highlighting the new developments since 2015 and to provide an overview of the main changes in unbundling-related provisions introduced in CEP. Topics explored included related issues such as: cases and reasons for reopening certification decisions; branding; financial independence in terms of staff and resources; compliance programmes and officers; investments, joint-venture TSOs and joint undertakings. Target Audience European Commission, energy suppliers, traders, gas/electricity customers, gas/electricity industry, consumer representative groups, network operators, Member States, academics and other interested parties. -
The Rise of Kleptocracy: Laundering Cash, Whitewashing Reputations
The Rise of Kleptocracy: Laundering Cash, Whitewashing Reputations Alexander Cooley, John Heathershaw, J.C.

Sharman Alexander Cooley is director of the Harriman Institute at Columbia University and Claire Tow Professor of Political Science at Barnard College. John Heathershaw is associate professor of international re- lations at the University of Exeter. J.C. Sharman is Sir Patrick Sheehy Professor of International Relations at the University of Cambridge. Kleptocracy and grand corruption are now under scrutiny as never be- fore. With renewed global attention on these abuses, a relatively clear picture has emerged of the domestic political economies shaped by klep- tocratic rule. Analysts have shown how state institutions are set up to allow elites and their families to systematically loot, while protecting these elites politically. In particular, this research has placed under the microscope the resource-rich countries that are vulnerable to kleptocrat- ic state capture. Yet to understand the operations of today’s jet-setting kleptocrats, one must look beyond the borders of the polities they despoil. Copi- ous news items feature kleptocrats and their families purchasing luxu- rious penthouses and cars; attending international cultural galas and charitable initiatives; and enlisting Western agents, lawyers, spokes- people, and pillars of the establishment to whitewash their reputations. -
Canadian Entities Involved in Global Laundromat Style Company Formations Background United Kingdom Legal Entities Have Long Been at the Heart of Known Laundromats
Canadian entities involved in global laundromat style company formations Background United Kingdom legal entities have long been at the heart of known laundromats. For example, the Proxy Platform, the Russian Laundromat, the Azerbaijani Laundromat and the Danske Bank scandal have all had a significant UK legal entity presence. These are primarily Limited Liability and Scottish Limited Partnerships but, to a lesser degree, private limited companies are also employed. These entities bear certain hallmarks which help to typify their activity, and which are explainable in terms of that activity. They are believed to be utilised for a number of reasons. 1. The UK has a mature online creation and filing service so remote access is easy and encouraged 2. The costs are low in order to encourage entrepreneurial activity in the UK economy 3. The UK is seen as a safe and prestigious location which provides a sense of security and assurance to banks who create bank accounts on their behalf. Hallmarks of a UK Laundromat entity Because the UK has a transparent corporate registry, it is possible to obtain significant levels of details about both entities that have been identified within Laundromats and those which bear the same or similar characteristics. Taking each entity in turn, they are: Limited Liability Partnerships (LLP) • Large numbers registered at the same, virtual address • The use of corporate “designated members” resident in offshore or secrecy locations • Failing to declare a “person with significant control” or, when they do, it is either -

Scalable Join Patterns
Scalable Join Patterns Claudio Russo Microsoft Research Joint work with Aaron Turon (Northeastern). Outline Join patterns Examples Implementation Optimizations Evaluation Conclusion Outline Join patterns Examples Implementation Optimizations Evaluation Conclusion Background Parallel programs eventually need to synchronize. I Writing correct synchronization code is hard. I Writing efficient synchronization code is harder still. Neglect efficiency and promised performance gains are easily eroded … …by the cost of synchronization! Can we make this easier for programmers? Goal Our Goal: I provide scalable, parallel synchronization I using declarative, high-level abstractions Our Recipe: 1. Take our favourite concurrency model: Join Calculus [Fournet & Gonthier] 2. Give it a scalable, parallel implementation. Join Calculus in a nutshell A basic calculus for message passing concurrency. Like π-calculus, but with a twist…. Definitions can declare synchronous and asynchronous channels. Threads communicate and synchronize by sending messages: I a synchronous send waits until the channel returns some result; I an asynchronous send returns immediately, posting a message. Chords Definitions contains collections of chords (a.k.a. join patterns). A chord pairs a pattern over channels with a continuation. The continuation may run when these channels are filled. Each send may enable: some pattern causing a request to complete or a new thread to run; no pattern causing the request to block or the message to queue. All messages in a pattern are consumed in one atomic step. Example§ (C#) ¤ Asynchronous.Channel Knife, Fork; // () -> void ¦Synchronous.Channel Hungry, SpoonFeed; // () -> void ¥ Calling Hungry() waits until the channel returns control (a request). Calling Knife(); returns immediately, but posts a resource. §Chords specify alternative reactions to messages.
