Efficient Runtime Support for Future Programming Standards
Because of the increasing number of cores on a single chip and in order to profit from the potential of accelerators in compute clusters, message passing paradigms like MPI are often no longer sufficient to utilize the hardware in an optimal way. Therefore a growing number of applications will employ a hybrid approach for parallelization, like MPI+OpenMP or MPI+OpenACC or even MPI+OpenMP+OpenACC. The recent version 4.0 of the OpenMP specification addresses this by incorporating programming support for accelerator devices and SIMD units in modern microarchitectures. This increases the complexity of application development and correctness checking for parallel applications. In ELP, a modified OpenMP runtime will be developed, delivering runtime internal information to correctness analysis tools like MUST or debuggers like DDT. This will allow detecting certain error classes automatically. The data will also be used by the performance analysis tool Vampir to better understand the performance behavior of an application.

Hybrid Parallelism for the Jülich Code FLEUR
The full-potential all-electron DFT code "fleur" is in active use for research by the group in Forschungszentrum Jülich (FZJ) and has additionally an international user base with about 1000 registered users from all over the world. The code has its special strength in the description of surface properties and magnetic materials, heterogeneous and multicomponent solids, but can handle all chemical elements of the periodic table and thus is also applied to materials containing 5d-elements or those with 4f- or 5f- electrons.
A major difficulty in the applicability of the FLEUR is the insufficient scaling behavior for large structures, which limits the possibility to simulate large unit-cells frequently encountered in disordered or multicomponent systems or in situations in which structural or chemical defects become of significant importance.
Since 2014 the Jülich Aachen Research Alliance (JARA) supports the cooperation with FZJ to implement hybrid parallelisation which will allow for using current and future supercomputers to perform large DFT calculations. The final version of the program should not only enable the use of several hundreds of nodes but also incorporate a memory efficient OpenMP parallelization for obtaining a high single-node performance.

Hyperslice Visualization of Metamodels for Manufacturing Processes
In the second phase of the Cluster of Excellence “Integrative Production Technology for High-Wage Countries” the Virtual Production Intelligence (VPI) platform is being developed. It is a holistic and integrative concept for the support of collaborative planning, monitoring and control of core processes within production and product development in various application fields. In the context of the VPI we are developing a tool for the explorative visualization of multi-dimensional meta-model data, which is based on the concept of hyperslices, linked with a 3D volume representation. The tool is applicable to various scenarios of multi-dimensional data analysis, but the concrete use case in the current project is to find ideal configuration parameters for laser cutting machines in the context of factory planning. more
Interactive Physically-based Sound Synthesis
While visual feedback is often the main focus in Virtual Environments, sound is another important modality. Auditory feedback can enhance the immersion and believability of virtual scenes. However, the common approach of using pre-recorded sound samples is often not feasible for highly interactive environments, because too many sounds would have to be recorded or designed upfront. Especially with physically simulated objects, a lot of sounds are generated by collisions between objects. The sound of such collisions depends on different factors: the material and shape of the objects, as well as the positions, strength and temporal distribution of the collision forces. Especially the latter aspects are difficult to reproduce with sound samples. more

Performance, Optimization and Productivity - POP
Using performance analysis tools and optimizing code for HPC architectures is a cumbersome task which often requires in depth expert knowledge in HPC. Because of current trends of computing architectures to use accelerators, more cores and deeper memory hierarchies, this complexity is going to increase further in the foreseeable future. Therefore, the POP (Performance, Optimization and Productivity) project offers services in performance analysis and performance optimization to code developers in industry and academia to connect code developers and HPC experts. This shall allow to integrate performance optimization in the software development process of HPC applications. The POP project gathers experts from the Barcelona Supercomputer Center (BSC), the High Performance Computing Center Stuttgart (HLRS), the Jülich Supercomputing Centre (JSC), the Numerical Algebra Group (NAG), TERATEC und the IT Center of RWTH Aachen University.
POP is one of the eight Centers of Excellence in HPC that have been promoted by the European Commission within Horizon 2020.

At the same time, the group releases production quality benchmark suites like SPEC MPI2007, SPEC OMP2012, and SPEC ACCEL, that can evaluate all dimensions of parallelism. These benchmark suites are used in academia and industry to conduct research in HPC systems, facilitate procurement, testing, and tuning of HPC systems. more
UNiform Integrated Tool Environment - UNITE
High-performance clusters often provide multiple MPI libraries and compiler suites for parallel programming. This means that parallel programming tools which often depend on a specific MPI library, and sometimes on a specific compiler, need to be installed multiple times, once for each combination of MPI library and compiler which has to be supported. In addition, over time, newer versions of the tools also get released and installed. One way to manage many different versions of software packages, used by many computing centers all over the world, is the "module" software. However, each center provides a different set of tools, has a different policy on how and where to install different software packages, and how to name the different versions. UNITE tries to improve this situation for debugging and performance tools. more
