Frequently Asked Questions

Visit the ACCESS Home page to learn about all of the ACCESS Tracks and plans for the transition from XSEDE to ACCESS.

The XSEDE User Portal (XUP) has been retired, making way for the new ACCESS Support Portal that went live on Sept 1, 2022. Initially, our goal is to transition basic XUP functionality to enable the research community to continue to use ACCESS resources (previously known as XSEDE resources). Existing content has been moved over 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 will remain the same in the ACCESS Support portal and no action by you is required.

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.

Tickets that have been assigned to Resource Providers directly will remain open so no action is required for these, although we encourage you to close out those you can. General XSEDE helpdesk tickets that were still open on September 1 have been closed, so those will need to be resubmitted.

Please contact us to discuss responses to the NSF22-574 “Training-based Workforce Development for Advanced Cyberinfrastructure (CyberTraining)” solicitation.

We will be introducing details about participation in the ACCESS Support program both as an individual, and as an organization, as the program gets underway. Join the ACCESS Support Affinity Group today to receive updates on program development, particularly the pilots that we are conducting for our new service offerings from September 2022 through March 2023.

As described in the NSF ACCESS solicitation, the Computational Science Support Network (CSSN) will "assimilate and coordinate the human capital that is separately funded by NSF at the national, regional and campus levels, and engage with the relevant existing community organizations and structures. This includes, but is not limited, to the existing Campus Champions service, Campus Research Computing Consortium (CaRCC), and activities previously supported through the XSEDE project, among others, as well as relevant projects and individuals funded in the future. The CSSN will actively assist prospective, new, and current users through activities ranging from campus-level, one-on-one user engagements to regional and national community events"

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. The ACCESS CSSN program will provide incentives for community organizations and individual members to encourage contributions. Financial incentives will be available to support a number of activities, including resourcing training, participation in community discussion forums, and leading affinity groups. Opportunities for active and up-and-coming leaders in our community to participate in advisory roles will also be available.

The ACCESS Support team looks forward to working with the community to develop the CSSN. More details on this process will be available in upcoming months.

ECSS-like services will be supported through MATCHPremier services. A key difference is that researchers requesting MATCHPremier services will pay for the consultant providing services using grant funds and/or supplemental funds from their funding entity. A key strategy is to connect consultants to work on specific projects as characterized by researchers using keywords or tags selected 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 strive to partner with to deliver our services. The ACCESS Support team will work with the Champions Leadership Team to determine how best to navigate their role in the CSSN.

PEARC22 conference subsidies were handled by the XSEDE Campus Champions program. Subsidies for subsequent year PEARC conferences will be available to CSSN participants with priority given to active contributors to ACCESS Support programs. More details on these subsidies, and how to apply, will be available in the upcoming months.

Affinity Groups

Joining ACCESS Resource Provider Affinity Groups (AGs) will add you to the distribution list for notifications about outages, news, and training events specific to the Resource Provider named. Affinity Groups encourage community members to gather based on common interests, and they provide connections to AG-specific slack channels, Q&A Forums, events, and relevant Knowledge Base resources.
