Information on precautionary site access restrictions to Fermilab's Batavia site in response to coronavirus/COVID-19 We continue to review all events currently planned for the next sixty days and organizers will be notified if their event must be canceled, postponed, or held remotely. Please, check back on Indico during this time for updates regarding your meeting specifics. As DOE O 142.3A, Unclassified Foreign Visits and Assignments Program (FVA) applies not only to physical access to DOE sites, technologies, and equipment, but also information, all remote events hosted by Fermilab must comply with FVA requirements. This includes participant registration and agenda review. Please contact Melissa Ormond, FVA Manager, with any questions.
In order to enable an iCal export link, your account needs to have an API key created. This key enables other applications to access data from within Indico even when you are neither using nor logged into the Indico system yourself with the link provided. Once created, you can manage your key at any time by going to 'My Profile' and looking under the tab entitled 'HTTP API'. Further information about HTTP API keys can be found in the Indico documentation.
Additionally to having an API key associated with your account, exporting private event information requires the usage of a persistent signature. This enables API URLs which do not expire after a few minutes so while the setting is active, anyone in possession of the link provided can access the information. Due to this, it is extremely important that you keep these links private and for your use only. If you think someone else may have acquired access to a link using this key in the future, you must immediately create a new key pair on the 'My Profile' page under the 'HTTP API' and update the iCalendar links afterwards.

High Energy Physics experiments continue to become more data and simulation intensive. There is an expected factor of ten gap (or more) between projected computing needs for HL-LHC experiments and projected growth of current HEP resources. In the US, High Performance Computing resources are going to be growing by more than an order of magnitude by 2021/2022 with the deployment of the US DOE's first exascale supercomputers. These resources are already becoming an important piece of the HEP computing landscape and will continue to become more important.
One challenge of using leadership computing resources is reading and writing data in scalable ways that does not lead to bottlenecks or performance penalties on the shared filesystems. This Workshop aims to bring together leading IO experts in the HEP field with experts from DOE ASCR Facilities to discuss how to move forward in the next years to make HEP software more friendly to millions of parallel threads accessing files on shared disks.
Quick introduction to Object Stores which the facilities indicate will be the leading scalable IO tool for the next ten years of Exascale.
HEP Transient Object Store1h 30m
Deeper dive into R&D being done in HEP related to Object Stores. How can these solutions be generalized? How can LHC experiments utilized Object Stores to enable large scale IO on HPCs?
Friday Afternoon Discussion
This session will be focused on how compression impacts scalable IO in HEP experiments. Most experiments store their data using compression. Can we utilize non-CPU resources to do this? What would the impact be on uncompressing on CPUs if compressed on GPUs? What tools can we use? ROOT? ZLIB?

Future Directions, Proposals, Action Items.1h 55m
What action items have we identified. What joint projects can be tackled to prepare for Exascale use? ROOT IO? Object Stores?
Boxed lunches will be handed out during the last 30 minutes of Peter and Brian's discussion.
