APS Upgrade Virtual Q&A Session
Dec 6 @ 12:00 pm – 1:00 pm

APS Upgrade Virtual Q&A Session

Don’t forget to register for the latest in Argonne’s series of APS Upgrade virtual Q&A sessions, to be held on Wednesday, December 6 from Noon – 1:00 p.m. CT. This will be your opportunity to ask questions about the return to user operations in 2024.

Panelists for the Q&A session include:
• Jim Kerby, director of the APS Upgrade Project
• Jonathan Lang, director of the X-ray Science Division at Argonne
• Connie Vanni, assistance manager, APS User Programs

Event Details

Wednesday, December 6
Noon – 1:00 p.m. CT


After brief presentations, our panelists will answer your questions about the upgrade. Other experts will be available to answer specific and technical questions about the project and the scientific benefits of the upgraded APS as well.
To register for the Q&A session, please complete the registration.
You will receive instructions for how to join the meeting in a follow-up e-mail.
You also have one more week to send in questions in advance for the Q&A session. If you would like to submit a question, please email it to Panelists will also answer questions asked live in the session.
If you have questions about the virtual session, send email to Up-to-date news on the APS Upgrade will be posted online. Thank you for your continued support of the APS Upgrade, and we look forward to answering your questions.

Title: “Data Transfer Solutions for Next-Generation Research Networks”

Date: Friday, December 15, 2023

Time: 2:00 pm

Location: 433/C010 or TEAMS

Research networks provide high-speed wide-area network connectivity between research and education institutions to facilitate large-scale data transfers. However, scalability issues of legacy transfer applications (e.g., scp and FTP) and their extensions (e.g., GridFTP and rsync) hinder the effective utilization of these networks. We propose online optimization algorithms to tune the degree of parallelism for file transfers to maximize transfer throughput while keeping system overhead at a minimum. First, we introduce Falcon that utilizes game theory-inspired novel utility function to evaluate the performance of various parallelism levels such that competing transfers are guaranteed to converge to a fair and stable solution. We assessed the performance of Falcon in isolated and production high-speed networks and found that it can discover optimal transfer parallelism in as little as 20 seconds and outperform the state-of-the-art solutions by more than 2x. On the other hand, Falcon uses the same level of parallelism for network and I/O operations which may result in increased system overhead and unfair resource allocation. To address this issue, we developed modular file transfer architecture, Marlin, that separates I/O and network operations so that parallelism can be independently adjusted for each component. Marlin adopts online gradient descent algorithm to swiftly search the solution space and find the optimal level of parallelism for read, transfer, and write operations. Experimental results collected under various network settings show that Marlin can identify and use a minimum parallelism level for each component, reducing system overhead (e.g., low CPU usage and I/O contention) and improving fairness among competing transfers.
