Archer is a data race detector for OpenMP programs. Archer combines static and dynamic techniques to identify data races in large OpenMP applications, leading to low runtime and memory overheads, while still offering high accuracy and precision. It builds on open-source tools infrastructure such as LLVM, ThreadSanitizer, and OMPT to provide portability.

Boronization is commonly utilized in tokamaks to suppress intrinsic impurities, most notably oxygen from residual water vapor. However, this is a temporary solution, as oxygen levels typically return to pre-boronization levels following repeated plasma exposure. The global impurity migration model WallDYN has been applied to the post-boronization surface impurity evolution in NSTX-U. A "Thin Film Model" has been incorporated into WallDYN to handle spatially inhomogeneous conditioning films of varying thicknesses, together with an empirical boron conditioning model for the NSTX-U glow discharge boronization process. The model qualitatively reproduces the spatial distribution of boron in the NSTX-U vessel, the spatially-resolved divertor emission pattern, and the increase in oxygen levels following boronization. The simulations suggest that oxygen is primarily sourced from wall locations without heavy plasma flux or significant boron deposition, namely the lower and upper passive plates and the lower private flux zone.

The Modelica IBPSA library is a free open-source library with basic models that codify best practices for the implementation of models for building and community energy and control systems. The development of the IBPSA library is organized through the IBPSA Project 1 (https://ibpsa.github.io/project1) of the International Building Performance Simulation Association (IBPSA). This library is typically not used directly by end-users. Rather, it is integrated by developers of other Modelica libraries for building and community energy systems, who then distribute it to end-users as part of their respective library.

The Building Informatics Environment is a modeling environment based on the Modelica language. The environment allows users to create a computer model of a building and its energy systems with various time scales and physical resolutions. The environment can be used for rapid development of e.g. demand controls algorithms new HVAC system solutions and new operational strategies. Models for building energy and control systems are made available in the environment. The models can be used as provided or they can be changed or linked with each other in order to model the effects that a particular user is interested in.

Flexible communication routines that enable high-performance computing (HPC) applications to operate with less synchronization are a great benefit to application algorithm creation and developer productivity. Further, communication operations that reduce synchronization in HPC applications while continuing to scale well are critical to application performance in the exascale era. We have implemented mechanisms that allow an application to scalably execute bcast/iAllReduce from any MPI rank without specifying the origin of the message in advance, demonstrating application development flexibility, highly scalable operation, and reduced application synchronization.
