Noise Removal from Remote Sensed Images by NonLocal Means with OpenCL Algorithm

Remote Sensing, 2020
We introduce a multi-platform portable implementation of the NonLocal Means methodology aimed at noise removal from remotely sensed images. It is particularly suited for hyperspectral sensors for which real-time applications are not possible with only ...

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 ...

A Survey of Techniques for Improving Security of GPUs

, 2018
Graphics processing unit (GPU), although a powerful performance-booster, also has many security vulnerabilities. Due to these, the GPU can act as a safe-haven for stealthy malware and the weakest `link' in the security `chain'.
