Abstract The paper provides a detailed estimation of the interfaces that exist in a split SURF-SPS execution model and provides a qualitative comparison to an integrated SURF-SPS execution model. A comprehensive matrix of dependencies between SURF and SPS is presented and is categorized into engineering, procurement, construction/fabrication and installation work packages. The matrix is used to illustrate the exact scope dependencies and thus, the sources of interfaces. A hypothetical greenfield development has been assumed to develop the interface matrix and to use it for comparison of the two execution models. The comparison also reveals how interfaces are naturally eliminated in an integrated SURF-SPS execution model. In each of the workstreams (E-P-C-I), top risks have been identified and monetary liability estimates for those risks have been provided. By transfer of these risks from company to contractor, monetary liability gets transferred to the contractor, thus, resulting in significant savings for operating companies. The following tangible results are provided in the paper: a) % of interface(s) reduced in the E-P-C-I areas; b) Risk reduction in monetary terms for operators – estimated values. This paper justifies the fact that there is a significant interface scope and risk reduction for operators, if they adopt an integrated SURF-SPS execution model.

The increasing control complexity of Noisy Intermediate-Scale Quantum (NISQ) systems underlines the necessity of integrating quantum hardware with quantum software. While mapping heterogeneous quantum-classical computing (HQCC) algorithms to NISQ hardware for execution, we observed a few dissatisfactions in quantum programming languages (QPLs), including difficult mapping to hardware, limited expressiveness, and counter-intuitive code. In addition, noisy qubits require repeatedly performed quantum experiments, which explicitly operate low-level configurations, such as pulses and timing of operations. This requirement is beyond the scope or capability of most existing QPLs. We summarize three execution models to depict the quantum-classical interaction of existing QPLs. Based on the refined HQCC model, we propose the Quingo framework to integrate and manage quantum-classical software and hardware to provide the programmability over HQCC applications and map them to NISQ hardware. We propose a six-phase quantum program life-cycle model matching the refined HQCC model, which is implemented by a runtime system. We also propose the Quingo programming language, an external domain-specific language highlighting timer-based timing control and opaque operation definition, which can be used to describe quantum experiments. We believe the Quingo framework could contribute to the clarification of key techniques in the design of future HQCC systems.

Buffer overflow (BO) is a well-known and widely exploited security vulnerability. Despite the extensive body of research, BO is still a threat menacing security-critical applications. The authors present a comprehensive systematic review on techniques intended to detecting BO vulnerabilities before releasing a software to production. They found that most of the studies addresses several vulnerabilities or memory errors, being not specific to BO detection. The authors organized them in seven categories: program analysis, testing, computational intelligence, symbolic execution, models, and code inspection. Program analysis, testing and code inspection techniques are available for use by the practitioner. However, program analysis adoption is hindered by the high number of false alarms; testing is broadly used but in ad hoc manner; and code inspection can be used in practice provided it is added as a task of the software development process. New techniques combining object code analysis with techniques from different categories seem a promising research avenue towards practical BO detection.
