    "abstract": "Broadcast systems continue their transition to standard commercial off-the-shelf (COTS) computing platforms and growing reliance on Graphic Processing Unit (GPU)-accelerated processing for real-time media transcoding, AI, and image manipulation demands optimized data exchange within compute nodes and across distributed systems. This shift introduces new challenges in memory sharing and communication. Using internode 1 Remote Direct Memory Access (RDMA): This study presents a comparative evaluation of memory sharing mechanisms across three distinct GPU transfer paths used in High-Performance Computing (HPC) and media processing: inter-node GPU-GPU, intra-node host-GPU and intra-node GPU-GPU memory exchange. The performance of each path is assessed under different software configurations: native memory operations without the aid of any communication framework-referred to as native, and higher-level abstractions, like Unified Communication X (UCX) 2 and Libfabric. 3 ’ Key performance metrics, including PCle 4 (Peripheral Component Interconnect Express) bandwidth, latency, and Central Processing Unit (CPU) utilization, are measured. These results are intended to support the development of applications that require efficient and cost-effective memory sharing between computational devices. Additionnally, this study highlights how higher-level communication frameworks provide flexible abstraction.",
