CERN's private OpenStack cloud offers more than 300,000 cores to over 3,500 users with services for compute, multiple storage types, baremetal, container clusters, and more.
CERN Cloud Team constantly works on improving these services while maintaining stability and availability that is critical for many services in IT and the experiment workflows.
This talk will cover the challenges and...
As CERN cloud service managers, one of our tasks is to make sure that the desired computational power is delivered to all users of our scientific community. This task is accomplished by monitoring the utilization metrics of each hypervisor and reacting to alarms in case of server saturation to mitigate the interference between VMs.
In order to maximize the efficiency of our cloud...
The File Transfer Service (FTS) is responsible for distributing the majority of the LHC data across the WLCG infrastructure. FTS schedules and executes data transfers, maximizing the use of available network and storage resources whilst easing the complexity of the grid environment by masking the details of the different underlying transfer protocols and storage endpoints.
The FTS service...
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...
