Package 'Slurmr'
Package ‘slurmR’ September 3, 2021 Title A Lightweight Wrapper for 'Slurm' Version 0.5-1 Description 'Slurm', Simple Linux Utility for Resource Management <https://slurm.schedmd.com/>, is a popular 'Linux' based software used to schedule jobs in 'HPC' (High Performance Computing) clusters. This R package provides a specialized lightweight wrapper of 'Slurm' with a syntax similar to that found in the 'parallel' R package. The package also includes a method for creating socket cluster objects spanning multiple nodes that can be used with the 'parallel' package.

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. -
Lock-Free Programming
Lock-Free Programming Geoff Langdale L31_Lockfree 1 Desynchronization ● This is an interesting topic ● This will (may?) become even more relevant with near ubiquitous multi-processing ● Still: please don’t rewrite any Project 3s! L31_Lockfree 2 Synchronization ● We received notification via the web form that one group has passed the P3/P4 test suite. Congratulations! ● We will be releasing a version of the fork-wait bomb which doesn't make as many assumptions about task id's. – Please look for it today and let us know right away if it causes any trouble for you. ● Personal and group disk quotas have been grown in order to reduce the number of people running out over the weekend – if you try hard enough you'll still be able to do it.

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.
