The is-ought gap is a problem in moral philosophy observing that ethical judgments ("ought") cannot be grounded purely in truth judgments ("is"): that an ought cannot be derived from an is. This gap renders the following argument invalid: "It is true ...

Run-time monitoring has been one of the widely used techniques to realize robust smart contracts. In this paper, we show how we can abstract aspects of run-time monitoring through declarations of programming languages so that a majority of run-...${}^{}$${}^{}$${}^{}$${}^{}$${}^{}$

While developing software, developers must first read and understand source code in order to work on change requests such as bug fixes or feature additions. The easier it is for them to understand what the code does, the faster they can get ...

MPI’s low-level interface is prone to errors, leading to bugs that can remain dormant for years. MPI correctness tools can aid in writing correct code but lack a standardized benchmark for comparison. This makes it difficult for users to choose ...

To effectively utilize modern HPC clusters, inter-node communication and related single program, multiple data (SPMD) parallel programming models such as mpi are inevitable. Current tools and compilers that employ analyses of SPMD models often ...

This article addresses the long-standing problem of program correctness for programs that describe systems of parallel executing processes. We propose a new method for proving correctness of parallel implementations of high-level models expressed as ...

Witness validation is a formal verification method to independently verify software verification tool results, with two main categories: violation and correctness witness validators. Validators for violation witnesses in Java include Wit4Java and GWIT, ...

Refactoring is a common task in writing and maintaining software. Refactoring tools are available for a wide variety of programming languages, and they are intended to transform source code without altering the functional behaviour of the software ...

Remote Memory Access (RMA) programming models enable processes running on a distributed-memory computer to access and manipulate the memory of other processes directly. Such one-sided communication has the benefit that the receiving process is not ...

There is one faultless way of programming. It uses computer intelligence to validate computer code: formal verification. Yet for developers this faultless approach has remained alien, incomprehensible, and many miss out on its proven benefits. This set of ...

In this paper, we continue the investigation of graph-based reaction systems. We extend the notion by input and output states as well as admitted context sequences to model explicitly input–output relations and decision problems on the inputs. ...

The L4 API (Application Programming Interface) is a core component of the operating system, which serves as the interface between user-level processes and the microkernel, facilitating communication and interaction. It is crucial to ensure the ...

The partitioned point-to-point communication concept introduced with the MPI-4.0 standard can improve the communication efficiency of hybrid parallel execution models. It allows threads on the sender and the receiver side to start working on parts of a ...

Administration and maintenance of modern supercomputers requires monitoring not only the correctness of their work, but also the efficiency of their functioning. For these purposes, monitoring systems are used that constantly run on supercomputer ...

Cyber–physical systems (CPS) are often modelled using Simulink to simulate plant and controller behaviour by block diagrams. However, since the incomplete coverage of simulation, design using Simulink alone is insufficient for ensuring ...

Many of today's companies use Smart Contracts to represent and execute their business processes. Smart contracts are self-executed programs running over blockchain. In this context, composite smart contracts are used to represent ...

Smart contracts have been subjected to several attacks that have exploited various vulnerabilities of languages like Solidity, which has resulted in huge financial losses. The functioning and deployment of smart contracts are somewhat different ...

Go is a popular statically-typed industrial programming language. To aid the type safe reuse of code, the recent Go release (Go 1.18) published early 2022 includes bounded parametric polymorphism via generic types. Go 1.18 implements generic types using ...

Scaling bugs – errors that only manifest at large scale simulations, in terms of number of parallel workers or input size – are critical to detect early in the testing of HPC codes. If missed, these bugs can cause applications to either crash at ...

With the advent of ultra-low-power embedded processors, energy harvesting devices (EHDs) are becoming exceedingly prevalent. These devices are highly portable, self-sustainable, and once deployed, they can run for an extremely long time. They can ...
