Acceleware Theatre Presentation  

Computational Trade-Offs of Higher Order in Time RTM

Presented by Scott Quiring, Acceleware
Mon Oct 27 @ 3:30pm (High Performance Computing Theater, exhibition floor #1582)  
This presentation examines the computational trade-offs of higher order in time for RTM. It compares the hardware trade-offs for running RTM with 2nd order accurate temporal derivatives and 4th order accurate temporal derivatives. The exact difference in computational complexity depends on the RTM implementation.The timestep using 4th order accuracy can be much longer for the same level of accuracy theoretically leading to an overall savings in computational resources. This analysis is true for the main propagation, however practical RTM is often limited by hard disk speed, available random access memory (RAM), or data transfers between compute nodes in a distributed system. In this presentation we will discuss these additional elements and how they impact performance.

AxRTM: An Innovative Reverse Time Migration Application

Presented by Scott Quiring, Acceleware
Mon Oct 27 @ 10:30am, Tue Oct 28 @ 12:30pm, Wed Oct 29 @ 12:30pm
AxRTM is Acceleware's high performance Reverse Time Migration application. This presentation will highlight both new and existing features that make AxRTM a compelling choice: enhanced amplitude correctness, adaptive removal of low-frequency noise, and advanced grid features to reduce runtime while preserving image quality. Uniquely supporting multi-core CPUs, NVIDIA GPUs and Intel Xeon Phi coprocessors AxRTM is the most efficient RTM application on the market. AxRTM is available from Paradigm, OpenGeophysical, Tsunami, GeoTomo and Acceleware.

AxWave: Fast and Accurate Survey Design and 3D Modeling

Presented by Scott Quiring, Acceleware
Mon Oct 27 @ 13:30pm, Tue Oct 28 @ 10:30am, Wed Oct 29 @ 11:30am
AxWave is Acceleware’s high fidelity finite-difference full wavefield modeling application. Engineered to run on CPUs, GPUs and Xeon Phi, AxWave offers unparalleled speed and efficiency for 2D and 3D isotropic variable density modeling and pseudo acoustic modeling for VTI and TTI media. In this presentation we will provide a tour of the product's features and interface, including: survey geometry, absorbing boundaries, variable grid, and optimized update coefficients among others.

Full Waveform Inversion Roadmap Update

Presented by Scott Quiring, Acceleware
Mon Oct 27 @ 12:30pm, Tue Oct 28 @ 13:30pm, Wed Oct 29 @ 10:30am
Full Waveform Inversion (FWI) is a technology which is moving into the mainstream. In this presentation, we will demonstrate how to invert seismic data to derive high-resolution earth models by following an example inversion. Acceleware's FWI product roadmap will be shared.

Using GPUs to Solve Important Oil & Gas Challenges

Presented by Ty McKercher, NVIDIA
Mon Oct 27 @ 11:30am, Tue Oct 28 @ 11:30am
Geoscientists are using GPUs to help clearly identify hidden prospects, and increase hydrocarbon reserves.  This presentation will explain how the breadth of GPU-based applications across the oil & gas workflow are overcoming challenges to improve images of complex geologic structures, while at the same time increasing operational performance.  Advanced seismic algorithms can be implemented affordably using GPUs that increase per node compute density, and yield 5x improvement in throughput.
