Description
Several enhancements have been introduced in the Jefferson Lab infrastructure to increase the robustness of the existing integration with computing pools for a number of collaborations doing experimental research in High Energy Physics. JLAB has provisioned access, entry, and execution points which allow the multiple collaboration users at the facility to submit HTCondor jobs to various pools and accept jobs submitted from other facilities to run in its computing farm. Jefferson Lab has completed infrastructure enhancements in support of multi-VO Open Science grid operations for CLAS12, EIC, GlueX, and MOLLER. Two networks were established for grid-facing services: A Science DMZ network for data transfer nodes outside the firewall and a science portals network for less data-intensive services that benefit from application layer firewalling. The Lab’s existing 2x10Gbit ESNet connections are being upgraded to 2x100Gbit in 2022, which will result in the capability for end-to-end flows supporting reconstruction in addition to simulations. With the system and network upgrades in place, work is in progress on the infrastructure for SciTokens, which is essential for authorization and authentication using federated identities. Work at present involves CILogon, OSG, and JLab, and aims at using SciTokens in HTCondor jobs to support VO-differentiated access to storage on the Science DMZ, both through Open Science Data Federation (OSDF) and to dedicated storage resources.
