Researchers Develop Methodology to Assess the Quality of Legal Representation in Criminal Proceedings
Having a good defence attorney in criminal proceedings can largely determine whether a defendant retains their freedom, health and good name. Researchers at HSE University propose a method for predicting an attorney’s performance based on the outcomes of their previous cases. The methodology takes into account the severity of the charges, the complexity of the cases, and the most likely outcome, drawing on judicial statistics.

Algebra, Geometry, and AI: Russian and Vietnamese Mathematicians Discuss Current Research
A delegation of scientists from Hanoi visited the HSE Faculty of Computer Science and then took part in a Russian-Vietnamese conference in St Petersburg. The events were part of the three-year project ‘Flexibility and Computational Methods.’ Over the course of the project, the researchers have prepared joint publications and obtained new mathematical results.

When Pictures Hinder Understanding: Illustrations May Impede Learning of Abstract Ideas
Illustrations can help remember specific actions but do not always make abstract ideas easier to learn. Researchers from HSE University and Humboldt University compared how people learn from texts with different levels of abstractness. They found that participants remembered illustrations better and performed better on related tasks after reading a multimedia text about yoga asanas than after reading an abstract text about the Nash equilibrium. The findings could help improve the selection of illustrations for educational and informational materials. The study has been published in Learning and Instruction.

Promising Compilation to ARMv8 POP

Ch. 22. P. 1–28.
Podkopaev A., Lahav O., Vafeiadis V.
In press

We prove the correctness of compilation of relaxed memory accesses and release-acquire fences from the "promising" semantics of [Kang et al. POPL'17] to the ARMv8 POP machine of [Flur et al. POPL'16]. The proof is highly non-trivial because both the ARMv8 POP and the promising semantics provide some extremely weak consistency guarantees for normal memory accesses; however, they do so in rather different ways. Our proof of compilation correctness to ARMv8 POP strengthens the results of the Kang et al., who only proved the correctness of compilation to x86-TSO and Power, which are much simpler in comparison to ARMv8 POP.

A Survey of Programming Language Memory Models
Моисеенко Е. А., Podkopaev A., Кознов Д. В., Programming and Computer Software 2021 Vol. 47 No. 6 P. 439–456
A memory model defines the semantics of concurrent programs operating on a shared memory. The most well-known and intuitive memory model, sequential consistency, is too strong for modern languages as it forbids many outcomes observable on modern hardware as a result of compiler and CPU optimizations. This gave rise to so-called weak or relaxed memory models. In recent years dozens of (weak) ...

Making Weak Memory Models Fair
Lahav O., Namakonov E., Oberhauser J. et al., Proceedings of the ACM on Programming Languages 2021 Vol. 5 No. OOPSLA Article 98
Liveness properties, such as termination, of even the simplest shared-memory concurrent programs under sequential consistency typically require some fairness assumptions about the scheduler. Under weak memory models, we observe that the standard notions of thread fairness are insufficient, and an additional fairness property, which we call memory fairness, is needed. In this paper, we propose ...

Operational Aspects of C/C++ Concurrency
Podkopaev A., Sergey I., Nanevski A., / Series Computer Science "arxiv.org". 2016.
In this work, we present a family of operational semantics that gradually approximates the realistic program behaviors in the C/C++11 memory model. Each semantics in our framework is built by elaborating and combining two simple ingredients: viewfronts and operation buffers. Viewfronts allow us to express the spatial aspect of thread interaction, i.e., which values a ...

Performance of MD-Algorithms on hybrid systems-on-chip Nvidia Tegra K1 & X1

In this paper we consider the efficiency of hybrid systemson-a-chip for high-performance calculations. Firstly, we build Roofline performance models for the systems considered using Empirical Roofline Toolkit and compare the results with the theoretical estimates. Secondly, we use LAMMPS as an example of the molecular dynamic package to demonstrate its performance and efficiency in various ...

The SLAM-based Static Driver Verifier Research Platform (SDVRP), as a tool that systematically analyzes source code and allows writing custom SLIC rules for various platforms, provided a potent verification mechanism for an embedded software system based on ARM Cortex-M0 microprocessor. The correctness of this software is of particular importance in the sense that there are ...
