Frequently Asked Questions

Visit the ACCESS Home page to learn about all of the ACCESS Tracks.

If you are having trouble with your ID you can visit Identity Management.

Our goal is to deliver a comprehensive knowledge base that makes the need for tickets relatively rare. You can still submit tickets via a webform so we can route tickets more efficiently.

There is a calendar of events posted by the community and you can join the ACCESS Support Affinity Group to receive emails about trainings, our pilot programs, and program developments.

The goal of the ACCESS CSSN program is to provide crowd-sourced opportunities to meet the needs of the community, to engage community organizations and members in this process, and to be inclusive and collaborative. Financial incentives are available to support a number of activities: trainings, participation in community discussion forums, adding CI links via the CSSN Community Engagement program (CCEP). Opportunities for active and up-and-coming leaders in our community to participate in advisory roles are also available through serving on the CCEP Grant Committee, Ask.CI Committee, or MatchPlus/Premier Committee.

The ACCESS Support team looks forward to working with the community to further develop the CSSN. Contact us for more info or sign up here.

The CSSN Community Engagement Program (CCEP) offers travel support for CSSN members to recognize helpful contributions to the community. This includes PEARC and any conference of your choosing. Find out more about the CCEP Community Grants and Contribution Rewards.

The CSSN Community Engagement Program (CCEP) is accepting applications for travel support ($500-$2500) for CSSN members to recognize helpful contributions to the community. There are two ways to participate in the program:

1. Community Grant submissions to create new documentation, videos, tutorials or live events which must be approved before work is started. Submissions are reviewed once a month by the community grants committee.

2. Community Contribution Rewards where the submitter contributes first and then applies for a reward. Submissions are reviewed once a month by the Ask.CI committee.

You can run Open OnDemand in your browser with no client software installation required. You will be able to start computing immediately with a simple interface that makes Open OnDemand easy to learn and use. Find out more

Pegasus is a workflow management system enabling researchers to run computational workflows across ACCESS resources. Users will seamlessly be able to orchestrate jobs and data movements at different resource providers. At this point, Pegasus on ACCESS is mainly used for high throughput computing (HTC) workloads, consisting of jobs which can fit on a single compute node (single core, multicore, or single node MPI jobs). Pegasus comes with a variety of useful tools that allow users to keep track of their workflows, and debug them when failures occur. A workflow submit host is available for users to submit and manage workflows. Find out more

The XSEDE User Portal (XUP) was retired, and the ACCESS Support Portal went live on Sept 1, 2022. Basic XUP functionality was transitioned to enable the research community to continue to use ACCESS resources (formerly XSEDE resources). Content was moved to our Confluence documentation pages, upcoming outages, news and events are displayed, there are links to request allocations, create/manage ACCESS accounts, and view ACCESS usage metrics. Your username and password for the XSEDE User Portal remain the same in the ACCESS Support portal.

ECSS-like services are supported through MATCHPremier services. In the MATCHPremier program, consultants providing services are paid by grant funds and/or supplemental funds from the funding entity. We connect consultants to projects by keywords or tags that researchers select from a carefully curated vocabulary. Learn more about MATCHPlus here. Learn about our overall strategy here.

The Campus Champions are one of several important established communities of practice that the ACCESS Support team will partner with to deliver our services. The ACCESS Support team is working with the Champions Leadership Team to determine how best to navigate their role in the CSSN.

Please contact us to discuss responses to the NSF23-521 “Strengthening the Cyberinfrastructure Professionals Ecosystem (SCIPE)” solicitation.
