Reverse time migration (RTM) is a powerful seismic migration technique, providing geophysicists with the ability to create accurate 3D images of the subsurface. Steep dips? Complex salt structure? High velocity contrast? No problem. By splitting the upgoing and downgoing wavefields and combining them with an accurate velocity model, RTM can image even the most complex…

While a one-pass TTI RTM is much more computationally efficient, it adds code complexity. NVIDIA has a collection of very well documented sample code that lowers the barrier to a one-pass TTI RTM. This sample code includes other tricks, such as compression on GPUs, which alleviates bandwidth bottleneck caused by snapshots. All code is freely available under NDA and our team can help with implementation/optimization. If interested, please reach out to me at reynaldog@nvidia.com

Can I get a code sample? I mainly want to see the effect of A100 Cache Data Compression。

Hello Sazc,

Are you with a university or company? We can share the code once an NDA is in place. Email me at reynaldog@nvidia.com.

Thanks,
Rey
