Disruptive Technology 4: PCIeArch for RTM

Sign up or log in to save this to your schedule and see who's attending!

Seismic Imaging is a standard data processing technique used in creating an image of subsurface structures of the Earth from measurements recorded at the surface via seismic wave propagations captured from various sound energy sources.

Reverse Time Migration (RTM) is an advanced migration algorithm that solves wave equations both downward & upward through the earth model. The most popular ways to solve the resulting wave equations is using either stencil based method or FFT based method.

Dell has a unique architecture in its PowerEdge C4130 by employing flexible PCIe architecture which allows different configurations between CPU & GPU. The architecture allows you to connect 2 GPU per socket directly or 4 GPU per socket via PCIe Switch. It also allows you to have GPU direct using Infiniband adapters between different nodes.

Couple of highlights:
Flexible PCIe architecture to support various CPU: GPU configurations.
Allows PCIe Switches to be inserted in the architecture which enables low latency peer-peer traffic.
Allows GPU Direct using Infiniband adapters for multi-node scale out.

Here are some of the different configurations that can be exploited for RTM & our paper will try to go in-depth on which configuration might be better suited for RTM.

C4130 supports lot of different configurations but the goal of this paper would be to start with the topologies that we think will benefit RTM and build from there.
