Watch How Nvidia GPU is Being Used in Digital Rock Physics
Needless to say, GPUs have more to them than what a layman thinks of, and these guys at Advanced Research Computing at Virginia Tech are not only using but heavily relying on Nvidia GPU for their research on Digital Rock Physics.
James McClure, a Computational Scientist discusses how his team is using the NVIDIA Tesla GPU-accelerated Titan Supercomputer at Oak Ridge National Laboratory in a video that we have embedded below.
In case you are not up to date, Digital Rock Physics “is a relatively new computational discipline that relies on high-performance computing to study the behavior of fluids within rock and other geologic materials.”
McClure says that they have been looking at using GPUs for their research since 2007 because the team understands that GPU implementation can “efficiently parallelize” some of their methods.
Ever since they have started using Nvidia GPU, most of their “large-scale multiphase flow simulations” have relied on it alongside the Titan Supercomputer itself.
Heterogeneous node architectures are also important to us. While we rely on GPUs for our simulations, we use the CPU to perform in situ data analysis using tools that we have developed based on multiscale averaging theory. Having both CPUs and GPUs in the system is therefore valuable and important to us.
