The GPU OpenCL Guide
The EDEM OpenCL GPU module makes use of the latest GPU technology (General Purpose computing on Graphical Processing Units). By utilizing cutting edge GPU cards EDEM is able to deploy contact model calculations across literally thousands of processing cores and deliver simulation results many times faster than by using traditional desktop CPUs.
The EDEM OpenCL GPU solver engine is based on OpenCL to ensure cross-platform support on both Windows and Linux and also ensures that a wide range of GPU cards are supported regardless of manufacturer, whether that be Nvidia, AMD, or Intel.
The EDEM OpenCL GPU solver engine is integrated directly into the EDEM environment. Setting and running simulations with the new EDEM OpenCL GPU engine is as simple as enabling the GPU engine and then running EDEM OpenCL the same way you would any other simulation.
The range of GPU cards available and the technology behind them is constantly changing and moving fast so if you are not sure of what hardware you need please get in touch and our engineers will be happy to talk about results from our most recent rounds of testing.
As of EDEM 2018, EDEM GPU contains a fully double precision solver.
Key improvements to the EDEM OpenCL in EDEM 2019 include support for GPU API models and Multi-GPU support.
EDEM 2018.2 introduced support for multiple GPUs in a single simulation. This increases the available GPU memory, increasing the maximum size and number of particles per simulation as well as improving performance.
