abstract = {Technological advances in high performance computing and maturing physical models allow scientists to simulate weather and climate evolutions with an increasing accuracy. While this improved accuracy allows us to explore complex dynamical interactions within such physical systems, inconceivable a few years ago, it also results in grand challenges regarding the data visualization and analytics process. 

 

We present STRIELAD, a scalable weather analytics toolkit, which allows for interactive exploration and real-time visualization of such large scale datasets. It combines parallel and distributed feature extraction using high-performance computing resources with smart level-of-detail rendering methods to assure interactivity during the complete analysis process.},

abstract = {With the increasing power of the HPC hardware systems, numerical 

simulations are heading towards exa-scale computing. Early 

inspection and analysis of on-going large simulations enables domain 

experts to obtain first insight into their running simulation 

process and intermediate results. Compared to conventional postprocessing, 

such in-situ processing has the advantage of keeping 

data in memory, avoiding to store the large amount of raw data 

to disk, providing on-the-fly analysis, and preventing early failures 

in the simulation process. In this poster we present a distributed 

and scalable software infrastructure, which provides distributed insitu 

data processing, feature extraction and interactive exploration 

at user's front-end. We have integrated and extended our system to 

multiple simulation applications, ranging from Lattice-Boltzmann 

blood flow simulation to grid based simulation for propulsion systems. 

A user-interactive front-end is integrated to our system, allowing 

to directly interact with the visualization of running simulations, 

gain insight, and make decisions.},

abstract = {Today's simulations are typically not a single application but cover an entire tool chain. There is a tool for initial data creation, for partitioning this data, for actual solving, for afterward analysis, for visualisation. Each of these tools is separated and so is the data flow. This approach gets unfeasible for an exascale environment. The penalty for every data movement is extreme. A load balance optimised for the solver most likely does not hold true for the complete run time. Compared to tweaking each part, our solution is more disruptive: Merge the tools used and thereby improve overall simulation performance. In this paper, we provide a first step. We combine pre-processing, simulation core and post-processing. We outline our idea of a general pre-processing interface steering the overall simulation and demonstrate its applicability with the sparse geometry lattice-boltzmann code HemeLB, intended for hemodynamic simulations. 

The tasks of the interface start with partitioning and distributing simulation data. Main aspect is to balance load and communication costs of the entire simulation by using the costs of each simulation part. Measurement of these costs for each simulation cycle makes possible further performance improvement: Data can be redistributed in between cycles in order to achieve a better load balance according to these costs. Additionally, our interface offers the possibility for other easy-to-integrate extensions covering, e.g., an automated mesh refinement or fault tolerance awareness. Finally, we investigate the applicability of our interface within HemeLB. We exploit the integrated partitioning methods and especially consider latest HemeLB-specific in-situ result analysis and visualisation methods.},

abstract = {The growth of space debris is becoming a serious problem. There 

is an urgent need for mitigation measures based on maintenance, 

repair and de-orbiting technologies. Our video presents a virtual 

reality framework in which robotic maintenance tasks of satellites 

can be simulated interactively. The two key components of this 

framework are a realistic virtual reality simulation and an immersive 

interaction device. The peculiarity of the virtual reality simulation 

is the combination of a physics engine based on Bullet with 

an extremely efficient haptic rendering algorithm inspired by an 

enhanced version of the Voxmap-Pointshell Algorithm. A central 

logic module controls all states and objects in the virtual world. To 

enable the human operator an optimal immersion into the virtual environment, the DLR bimanual haptic device is used as interaction 

device. Equipped with two light-weight robot arms, this device is 

able to provide realistic haptic feedback at both human hands, while 

covering the major part of human operator's workspace. The applicability 

of this system is enhanced by additional force sensors, 

active hand interfaces with an additional degree of freedom, smart 

safety technologies and intuitive robot data augmentation. Our platform can be used for verification or training purposes of robotic 

systems interacting in space environments.},
