🚀 Highlights of 2026

1.Graviton: Data-Local Kubernetes Scheduler
A Kubernetes Operator built to eliminate Wide Area Network (WAN) data transfers in scientific data lakes (like the WLCG). It queries storage topologies (e.g., Rucio) and injects dynamic NodeAffinity into batch jobs to ensure compute is co-located with its dataset replicas.

  • Tech: Go, Kubernetes Operator SDK, Rucio, Prometheus.

2. RNArrow Gateway: ROOT-to-Arrow Flight Server [DOI: 10.5281/zenodo.20034922]
A standalone C++17 library and gRPC Flight server bridging CERN's next-generation RNTuple binary format with the Apache Arrow ecosystem. Achieves <1.6x overhead over raw C++ reads, exposing Petabyte-scale physics data natively to modern distributed analytic tools.

  • Tech: C++17, Apache Arrow, gRPC, pybind11, ROOT.

3.AXON-HLT: Coprocessor Inference Benchmarking [DOI: 10.5281/zenodo.20058280]
An asynchronous gRPC client simulating High-Level Trigger (HLT) ML pipelines. Validates the performance of "Coprocessors-as-a-Service" architectures by benchmarking dynamic batching on NVIDIA Triton servers, adhering to strict <7ms latency budgets for particle classification.

  • Tech: Python (asyncio), NVIDIA Triton Inference Server, PyTorch/ONNX, gRPC.
