Checkpointing of Parallel MPI Applications using MPI One-sided API with Support for Byte-addressable Non-volatile RAM
PublicationThe increasing size of computational clusters results in an increasing probability of failures, which in turn requires application checkpointing in order to survive those failures. Traditional checkpointing requires data to be copied from application memory into persistent storage medium, which increases application execution time as it is usually done in a separate step. In this paper we propose to use emerging byte-addressable...

Rural Landscapes of Roman (northern) Liburnia: Diachronic Development of Organisation and the Economy in Extra-Urban Territories in the Light of Recent Archaeological Research
PublicationThe archaeology of Roman rural landscapes in the province of Dalmatia, and especially northern Liburnia, has until recently focused on single-site or single-monument analyses, allowing for only geographically patchy and chronologically limited conclusions. Considering the results of recent research in the wider Kvarner and sub-Velebit area, the paper discusses issues of Roman extra-urban territorial organization, the formation...

Beyond the standard entropic inequalities: stronger scalar separability criteria and their applications
PublicationNiedawno pokazano, że jeżeli dwupodukładowy stan kwantowy spełnia strukturalne kryterium separowalności oparte na pewnym liniowym odwzorowaniu dodatnim (tzw. odwzorowanie redukcyjne) to musi także spełniać skalarne kryterium separowalności oparte na nierównościach entropijnych. Ponieważ nierówności te są obiecującymi z eksperymentalnego punktu widzenia detektorami splątania w układach kwantowych, interesującym wydaje się pytanie...

Contact with coupled adhesion and friction: Computational framework, applications, and new insights
PublicationContact involving soft materials often combines dry adhesion, sliding friction, and large deformations. At the local level, these three aspects are rarely captured simultaneously, but included in the theoretical models by Mergel et al., (2019). We here develop a corresponding finite element framework that captures 3D finite-strain contact of two deformable bodies. This framework is suitable to investigate sliding friction even...
