E4D is a 3D geophysical modeling and inversion program designed for subsurface imaging and monitoring. This award-winning R&D 100 E4D software provides customization for a wide range of field and laboratory applications, using:
E4D leverages distributed-memory high-performance computing, providing solutions for analyzing large geophysical datasets with high computational demands. E4D is highly scalable, and can be used on systems ranging from laptop computers to state-of-the-art supercomputing systems. The largest inversion executed to date involved a data set with approximately 5000 electrodes, 220,000 measurements, and a mesh with approximately 3 million elements, executed on NERSC supercomputing resources using 10,000 processors.
