In Situ Exploration of Particle Simulations with CPU Ray Tracing
We present a system for interactive in situ visualization of large particle simulations, suitable for general CPU-based HPC architectures. As simulations grow in scale, in situ methods are needed to alleviate IO bottlenecks and visualize data at full ...
In Situ Visualization and Production of Extract Databases
Simulations running at high concurrency on HPC systems generate large volumes of data that are impractical to write to disk due to time and storage constraints. Applications often adapt by saving data infrequently, resulting in datasets with poor ...
In situ, steerable, hardware-independent and data-structure agnostic visualization with ISAAC
The computation power of supercomputers grows faster than the bandwidth of their storage and network. In particular, applications using hardware accelerators like Nvidia GPUs cannot save enough data to be analyzed in a later step. There is a high risk ...
Preparing for In Situ Processing on Upcoming Leading-edge Supercomputers
High performance computing applications are producing increasingly large amounts of data and placing enormous stress on current capabilities for traditional post-hoc visualization techniques. Because of the growing compute and I/O imbalance, data ...
Analysis of CPU Usage Data Properties and their possible impact on Performance Monitoring
CPU usage data CPU user, system, iowait etc. load levels are often the basic data used for performance monitoring. The source of these data is the operating system. In this paper we analyze some properties of CPU usage data provided by the Linux kernel. ...
Parallel algorithm for 3D modeling of monochromatic acoustic field using integral equations
We present a parallel algorithm for solution of the three-dimensional Helmholtz equation in the frequency domain using volume-integral equations. The algorithm is applied to seismic forward modeling. The method of integral equations reduces the size of ...
