XDP_CLONE: Efficient In-Driver Packet Duplication for eBPF-Accelerated Systems

This work presents XDP_CLONE, a system that performs packet duplication directly within the network driver, eliminating socket buffer allocation and significantly reduces overhead and improves performance for eBPF network applications up to 2.3x.

High-Performance Tensor Formulation of the Viterbi Algorithm for Hidden Semi-Markov Models

This work presents a tensor-based formulation of the Viterbi algorithm for HSMMs, restructuring the inner loops into tensor operations that naturally map onto SIMD units and massively parallel architectures and provides optimized implementations spanning single- and multi-core CPUs, and, for the first time, GPU.
