Two graduate students working with ESnet have published their papers recently in IEEE and ACM workshops.
Bibek Shrestha, a graduate student at the University of Nevada, Reno, and his advisor Engin Arslan worked with Richard Cziva from ESnet to publish a work on “INT Based Network-Aware Task Scheduling for Edge Computing”. In the paper, Bibek investigated the use of in-band network telemetry (INT) for real-time in-network task scheduling. Bibek’s experimental analysis using various workload types and network congestion scenarios revealed that enhancing task scheduling of edge computing with high-precision network telemetry can lead up to a 40% reduction in data transfer times and up to 30% reduction in total task execution times by favoring edge servers in uncongested (or mildly congested) sections of the network when scheduling tasks. The paper will appear in the 3rd Workshop on Parallel AI and Systems for the Edge (PAISE) co-conducted with IEEE IPDPS 2021 conference to be held on May 21st, 2021, in Portland, Oregon.
Zhang Liu, a former ESnet intern and a current graduate student at the University of Colorado at Boulder, worked with the ESnet High Touch Team – Chin Guok, Bruce Mah, Yatish Kumar, and Richard Cziva – on fastcapa-ng, ESnet’s telemetry processing software. In the paper “Programmable Per-Packet Network Telemetry: From Wire to Kafka at Scale,” Zhang showed the scaling and performance characteristics of fastcapa-ng, and highlighted the most critical performance considerations that allow the pushing of 10.4 million telemetry packets per second to Kafka with only 5 CPU cores, which is more than enough to handle 170 Gbit/s of original traffic with 1512B MTU. This paper will appear in the 4th International Workshop on Systems and Network Telemetry and Analytics (SNTA 2021) held at the ACM HPCD 2021 conference in Stockholm, Sweden between 21-25 June 2021.
Congratulations Bibek and Zhang!
