Eliis/PaleoScan unveils Open CL-based acceleration

PaleoScan user meet sees novel geobody extraction, API and hardware acceleration.

Eliis hosted the PaleoScan user meeting last month in Montpellier, France, introducing new interpretation functionality to its guided sequence stratigraphic seismic interpretation toolset. These include geobody extraction, multi core optimization a data link to Schlumberger’s Petrel and an API for developers.

A new flattening/horizon stack function is useful in visualizing structural evolution of both seismic and log cross sections in synchronized windows. Hardware acceleration eschews Nvidia’s ubiquitous Cuda, Eliis’ developers have opted instead for the OpenCL standard which promises a more portable route to acceleration via multi core CPUs and GPUs.

Tests using an Nvidia GT440 accelerator showed speed up in the range of 3 to over 60x for various compute intensive tasks. Further ‘dramatic’ speed-up of most tasks was reported by users of solid state disks.

Eliis is now working on enhanced management of CPU/GPU acceleration along with PsDataIO, a C++ library used develop the Petrel data link and now available for third party use.
