Opinion mining, also known as sentiment analysis, is a subfield of natural language processing (NLP) that focuses on identifying and extracting subjective information in textual material. This can include determining the overall sentiment of a piece of text (e.g., positive or negative), as well as identifying specific emotions or opinions expressed in the text, that involves the use of advanced machine and deep learning techniques. Recently, transformer-based language models make this task of human emotion analysis intuitive, thanks to the attention mechanism and parallel computation. These advantages make such models very powerful on linguistic tasks, unlike recurrent neural networks that spend a lot of time on sequential processing, making them prone to fail when it comes to processing long text. The scope of our paper aims to study the behaviour of the cutting-edge Transformer-based language models on opinion mining and provide a high-level comparison between them to highlight their key particularities. Additionally, our comparative study shows leads and paves the way for production engineers regarding the approach to focus on and is useful for researchers as it provides guidelines for future research subjects.

Metaobject Protocols and Type Checks, do they have much in common? Perhaps not from a language perspective. However, under the hood of a modern virtual machine, they turn out to show very similar behavior and can be optimized very similarly. This talk will go back to the days of Terminator 2, The Naked Gun 2 1/2, and Star Trek VI. We will revisit the early days of just-in-time compilation, the basic insights that are still true, and see how to apply them to metaprogramming techniques of different shapes and forms.

Seminar on Parallel and Concurrent Programming

Stefan Marr

Communicating Event-Loop Languages similar to E and AmbientTalk are recently gaining more traction as a subset of actor languages. With the rise of JavaScript, E’s notion of vats and non-blocking communication based on promises entered the mainstream. For implementations, the combination of dynamic typing, asynchronous message sending, and promise resolution pose new optimization challenges. This paper discusses these challenges and presents initial experiments for a Newspeak implementation based on the Truffle framework. Our implementation is on average 1.65x slower than Java on a set of 14 benchmarks. Initial optimizations improve the performance of asynchronous messages and reduce the cost of encapsulation on microbenchmarks by about 2x. Parallel actor benchmarks further show that the system scales based on the workload characteristics. Thus, we conclude that Truffle is a promising platform also for communicating event-loop languages.

Optimizing Communicating Event-Loop Languages with Truffle

Stefan Marr

Tracing and partial evaluation have been proposed as meta-compilation techniques for interpreters to make just-in-time compilation language-independent. They promise that programs executing on simple interpreters can reach performance of the same order of magnitude as if they would be executed on state-of-the-art virtual machines with highly optimizing just-in-time compilers built for a specific language. Tracing and partial evaluation approach this meta-compilation from two ends of a spectrum, resulting in different sets of tradeoffs. This study investigates both approaches in the context of self-optimizing interpreters, a technique for building fast abstract-syntax-tree interpreters. Based on RPython for tracing and Truffle for partial evaluation, we assess the two approaches by comparing the impact of various optimizations on the performance of an interpreter for SOM, an object-oriented dynamically-typed language. The goal is to determine whether either approach yields clear performance or engineering benefits. We find that tracing and partial evaluation both reach roughly the same level of performance. SOM based on meta-tracing is on average 3x slower than Java, while SOM based on partial evaluation is on average 2.3x slower than Java. With respect to the engineering, tracing has however significant benefits, because it requires language implementers to apply fewer optimizations to reach the same level of performance.

Why Is Concurrent Programming Hard? And What Can We Do about It?

Stefan Marr

Runtime metaprogramming enables many useful applications and is often a convenient solution to solve problems in a generic way, which makes it widely used in frameworks, middleware, and domain-specific languages. However, powerful metaobject protocols are rarely supported and even common concepts such as reflective method invocation or dynamic proxies are not optimized. Solutions proposed in literature either restrict the metaprogramming capabilities or require application or library developers to apply performance improving techniques. For overhead-free runtime metaprogramming, we demonstrate that dispatch chains, a generalized form of polymorphic inline caches common to self-optimizing interpreters, are a simple optimization at the language-implementation level. Our evaluation with self-optimizing interpreters shows that unrestricted metaobject protocols can be realized for the first time without runtime overhead, and that this optimization is applicable for just-in-time compilation of interpreters based on meta-tracing as well as partial evaluation. In this context, we also demonstrate that optimizing common reflective operations can lead to significant performance improvements for existing applications.

Zero-Overhead Metaprogramming: Reflection and Metaobject Protocols Fast and w...

Stefan Marr

This talk shows how languages can be implemented as self-optimizing interpreters, and how Truffle or RPython go about to just-in-time compile these interpreters to efficient native code. Programming languages are never perfect, so people start building domain-specific languages to be able to solve their problems more easily. However, custom languages are often slow, or take enormous amounts of effort to be made fast by building custom compilers or virtual machines. With the notion of self-optimizing interpreters, researchers proposed a way to implement languages easily and generate a JIT compiler from a simple interpreter. We explore the idea and experiment with it on top of RPython (of PyPy fame) with its meta-tracing JIT compiler, as well as Truffle, the JVM framework of Oracle Labs for self-optimizing interpreters. In this talk, we show how a simple interpreter can reach the same order of magnitude of performance as the highly optimizing JVM for Java. We discuss the implementation on top of RPython as well as on top of Java with Truffle so that you can start right away, independent of whether you prefer the Python or JVM ecosystem. While our own experiments focus on SOM, a little Smalltalk variant to keep things simple, other people have used this approach to improve peek performance of JRuby, or build languages such as JavaScript, R, and Python 3.

Building High-Performance Language Implementations With Low Effort

Traffic monitoring or crowd management systems produce large amounts of data in the form of events that need to be processed to detect relevant incidents. Rule-based pattern recognition is a promising approach for these applications, however, increasing amounts of data as well as large and complex rule sets demand for more and more processing power and memory. In order to scale such applications, a rule-based pattern detection system needs to be distributable over multiple machines. Today’s approaches are however focused on static distribution of rules or do not support reasoning over the full set of events. We propose Cloud PARTE, a complex event detection system that implements the Rete algorithm on top of mobile actors. These actors can migrate between machines to respond to changes in the work load distribution. Cloud PARTE is an extension of PARTE and offers the first rule engine specifically tailored for continuous complex event detection that is able to benefit from elastic systems as provided by cloud computing platforms. It supports fully automatic load balancing and supports online rules with access to the entire event pool.

Supporting all known abstractions for concurrent and parallel programming in a virtual machines (VM) is a futile undertaking, but it is required to give programmers appropriate tools and performance. Instead of supporting all abstractions directly, VMs need a unifying mechanism similar to INVOKEDYNAMIC for JVMs. Our survey of parallel and concurrent programming concepts identifies concurrency abstractions as the ones benefiting most from support in a VM. Currently, their semantics is often weakened, reducing their engineering benefits. They require a mechanism to define flexible language guarantees. Based on this survey, we define an ownership-based meta-object protocol as candidate for VM support. We demonstrate its expressiveness by implementing actor semantics, software transactional memory, agents, CSP, and active objects. While the performance of our prototype confirms the need for VM support, it also shows that the chosen mechanism is appropriate to express a wide range of concurrency abstractions in a unified way.

Sly and the RoarVM: Parallel Programming with Smalltalk

Stefan Marr

While parallel programming for very regular problems has been used in the scientific community by non-computer-scientists successfully for a few decades now, concurrent programming and solving irregular problems remains hard. Furthermore, we shift from few expert system programmers mastering concurrency for a constrained set of problems to mainstream application developers being required to master concurrency for a wide variety of problems. Consequently, high-level language virtual machine (VM) research faces interesting questions. What are processor design changes that have an impact on the abstractions provided by VMs to provide platform independence? How can application programmers’ diverse needs be facilitated to solve concurrent programming problems? We argue that VMs will need to be ready for a wide range of different concurrency models that allow solving concurrency problems with appropriate abstractions. Furthermore, they need to abstract from heterogeneous processor architectures, varying performance characteristics, need to account for memory access cost and inter-core communication mechanisms but should only expose the minimal useful set of notions like locality, explicit communication, and adaptable scheduling to maintain their abstracting nature. Eventually, language designers need to be enabled to guarantee properties like encapsulation, scheduling guarantees, and immutability also when an interaction between different problem-specific concurrency abstractions is required.

The manycore future has several challenges ahead of us that suggest that fundamental assumptions of contemporary programming approaches do not apply anymore when scalability is required. Sly is a language prototype designed to experiment with the inherently nondeterministic properties of parallel systems. It is designed to enable programmers to embrace nondeterminism instead of guiding them to fight it. Nature shows that complex system can be built from independent entities that achieve a common goal without global synchronization/communication. Sly is design to enable the prototyping of algorithms that show such emerging behavior. It will be introduced in the first part of the talk. The second part of the talk will focus on the underlying problems of building virtual machines for the manycore future, which allow to harness the available computing power. The RoarVM was design to experiment on the Tilera TILE64 manycore processor architecture which provides 64 cores and characteristics that are distinctly different from today's commodity multicore processors. Memory bandwidth, caches and communication are the biggest challenges on such architectures and this talk will give a brief overview over the design choices of the RoarVM which tackle the characteristics of the TILE64 architecture. Acknowledgement: Sly and the RoarVM were designed and implemented by David Ungar and Sam Adams at IBM Research.

The multicore era comes with new challenges for software engineers. The Software Languages Lab and its Parallel Programming Group does research on languages and language runtimes/virtual machines for the new era of multi- and manycore hardware. This talk gives a brief introduction to the problem and names our approaches to tackle the challenges. However, since this is presented as a Pecha Kucha, the talk is very abstract and focuses on conveying the theme instead of technical details.

The Price of the Free Lunch: Programming in the Multicore Era

Stefan Marr

We propose to search for common abstractions for different concurrency models to enable high-level language virtual machines to support a wide range of different concurrency models. This would enable domain-specific solutions for the concurrency problem. Furthermore, advanced knowledge about concurrency in the VM model will most likely lead to better implementation opportunities on top of the different upcoming many-core architectures. The idea is to investigate the concepts of encapsulation and locality to this end. Thus, we are going to experiment with different language abstractions for concurrency on top of a virtual machine, which supports encapsulation and locality, to see how language designers could benefit, and how virtual machines could optimize programs using these concepts.

This paper presents an algorithm and a data structure for scalable dynamic synchronization in fine-grained parallelism. The algorithm supports the full generality of phasers with dynamic, two-phase, and point-to-point synchronization. It retains the scalability of classical tree barriers, but provides unbounded dynamicity by employing a tailor-made insertion tree data structure. It is the first completely documented implementation strategy for a scalable phaser synchronization construct. Our evaluation shows that it can be used as a drop-in replacement for classic barriers without harming performance, despite its additional complexity and potential for performance optimizations. Furthermore, our approach overcomes performance and scalability limitations which have been present in other phaser proposals.

The upcoming many-core architectures require software developers to exploit concurrency to utilize available computational power. We argue that today's virtual machines (VMs), which are a cornerstone of software development, do not provide sufficient abstraction for concurrency concepts. To overcome this shortcoming, we propose to integrate concurrency operations into VM instruction sets. Since there will always be VMs optimized for special purposes, our goal is to develop a methodology to design instruction sets with concurrency support. Therefore, we also propose a list of tradeoffs that have to be investigated to advise the design of such instruction sets. As a first experiment, we implemented one instruction set extension for shared memory and one for non-shared memory concurrency. From our experimental results, we derived a list of requirements for a full-grown experimental environment for further research.

High-level language virtual machines (VMs) can be used on a wide range of devices as a basic part of the deployed software stack. As the available devices differ to a large degree in their applications and their available resources, distinct implementation strategies have to be used for certain parts of a VM to meet the special requirements. This paper motivates the need for an architecture definition language for complex software systems like VM implementations. The basic concepts and language constructs of this language, which is called VMADL, are introduced. To motivate further discussions, the benefits of this approach are briefly discussed.

Retrieval augmented generation (RAG) is the most popular style of large language model application to emerge from 2023. The most basic style of RAG works by vectorizing your data and injecting it into a vector database like Milvus for retrieval to augment the text output generated by an LLM. This is just the beginning. One of the ways that we can extend RAG, and extend AI, is through multilingual use cases. Typical RAG is done in English using embedding models that are trained in English. In this talk, we’ll explore how RAG could work in languages other than English. We’ll explore French, Chinese, and Polish.
