Multi-GPU Solver Capabilities

Rocky DEM’s unique ability to utilize one or more GPU (Graphics Processing Unit) cards on the same motherboard greatly speeds up the computational time and also allows for large-scale simulations involving tens of millions of particles.

How does it work?

Large-scale DEM simulations with millions of particles use huge amounts of hardware memory. CPU memory can be quite expensive and simulation performance can vary quite drastically.

A single CPU or GPU has a limited amount of memory, and the particle count that can be handled is still restricted to this memory only.

The multi-GPU solver in Rocky DEM, however, overcomes this memory restriction by efficiently distributing and managing the combined memory of two or more GPU cards within a single motherboard.
