ACCESS Program News

ACCESS at PEARC23

PEARC23 was quite the busy event this year, and ACCESS was well-represented both in presentations and on the exhibitor floor. We had many visitors to the booth, many of whom signed up for this very newsletter. We welcome our new subscribers, and we were happy to see so many of you at PEARC. We look forward to future connections and sharing our timely ACCESS updates with you each month!

NSF Calling for Proposals

ACCESS is looking to expand our services to research communities. The National Science Foundation (NSF) recently announced they're accepting proposals for a new ACCESS service area, the Cyberinfrastructure Technology Acceleration Pathway (CITAP). Proposals will be accepted until September 6, 2023.

ACCESS Operations News

STEP Summer Internships Wrap Up

The ACCESS Operations Student Training & Engagement Program (STEP) summer internship program has come to an end. Six students participated in a full-time internship during June and July and delivered final presentations about their various projects to Operations leadership this week.


Four of the students participated in the student program at PEARC23. Final papers are being published in the Operations document repository and will be publicly available soon. Two of the students will be selected to continue on to STEP-3, a part-time internship during the upcoming academic year.

ACCESS Metrics News

New XDMoD Data Analytics Framework

The new XDMoD Data Analytics Framework is available, providing programmatic access to the data in ACCESS XDMoD via a Python API and opening up analysis of the data to a broad range of data science and machine learning tools.


The ACCESS Monitoring and Measurement Service (MMS) team presented a tutorial at the PEARC23 conference in July showing how to use the new Data Analytics Framework.

Participants walked through example Jupyter Notebooks that are designed for self-guided instruction and are available through the xdmod-notebooks GitHub repository. Anyone with an ACCESS account can log in to ACCESS XDMoD, create an API token as instructed in the notebooks and use that token with the Python API to obtain and analyze data from ACCESS XDMoD.


The ACCESS MMS team welcomes contributions to the collection of Jupyter Notebooks and the Python API source code. Contributions can be made via GitHub Pull Requests. For further information about XDMoD or the Data Analytics Framework, or to schedule a training session, please contact the ACCESS MMS team via the ACCESS Ticket System.

Enhanced XDMoD Coverage Of Cloud Virtual Machines

The XDMoD cloud realm now includes non-active virtual machines (VMs) in its statistics and a “VM State” dimension that allows grouping of data by the VM status (Active, Shelved, etc). In prior versions of XDMoD, the statistics in the cloud realm only included data about VMs when they were active.


XDMoD will now also include data about VMs when they're not active; i.e., when they're paused, stopped, shelved, etc. For example, the Core Hours statistic only counted the time when a VM was turned on. That statistic, along with others, will now include data when a VM is turned off or shelved, and the new VM State dimension will allow users to see data for a statistic broken down by the state of a VM, with the state being Active, Inactive or Shelved. After these changes, in order to see the same data as before, you should look at the Active value in the VM State dimension.
