NVIDIA indeX is a GPU cluster-based software solution that enables scalable real-time visualization of large-scale data and is used in the Oil & Gas industries for seismic data interpretation. Here, the visualized large-scale stacked seismic data result from pre-processing multi-dimensional or multi-valued raw data, which is multiple times larger. For instance, pre-processing approx. 54 terabyte of pre-stacked data typically generates the seismic attributes of just a 90 gigabyte stacked dataset for visualization. Parallel and distributed computing algorithms are commonly used to process the multi-dimensional or multi-values data on compute clusters. The NVIDIA indeX visualization framework enables the seamless integration of user-defined parallel and distributed compute algorithms to generate seismic attributes. NVIDIA indeX triggers the external compute algorithms and populate the scalable large-scale data rendering algorithm with the resulting seismic attributes for immediate real-time display.
