Porting HEP Parameterized Calorimeter Simulation Code to GPUs

Frontiers in Big Data, 2021
The High Energy Physics (HEP) experiments, such as those at the Large Hadron Collider (LHC), traditionally consume large amounts of CPU cycles for detector simulations and data analysis, but rarely use compute accelerators such as GPUs.

Simple offset algorithm for generating workpiece solid model for milling simulation

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2017
In the milling simulation of a large stamping die for an automobile part, a workpiece solid model is necessary as an input data. The initial shape of the workpiece is generally equivalent to an offset shape of the stamping die CAD model.

Exploring GPU-to-GPU Communication: Insights into Supercomputer Interconnects

SC24: International Conference for High Performance Computing, Networking, Storage and Analysis
Multi-GPU nodes are increasingly common in the rapidly evolving landscape of exascale supercomputers. On these systems, GPUs on the same node are connected through dedicated networks, with bandwidths up to a few terabits per second. However, gauging performance expectations and maximizing system efficiency is challenging due to different technologies ...
