The engineers who develop Rocky DEM are continually striving for more efficient methods to accelerate the calculation speed. They know that the faster a simulation completes, the more productive Rocky DEM clients can be in their overall design process.

With the latest release of Rocky DEM, it is now possible to accelerate the computational workload by making use of one or more Graphics Processing Units (GPUs). This capability allows the calculations to be executed on the GPUs while control and data transmission are processed on the CPU. For typical cases that include large amounts of particles, it is possible to obtain simulation results many times faster than ever before. This is because the advanced capabilities of even a single GPU with 100+ cores is very well suited to DEM simulations; combining the shared ability of several GPUs only increases the processing power.
