Every spring, the entire Open Science Grid (OSG) community–consisting of resource owners and operators, users, and staff–gathers at the annual OSG all-hands meeting. The 2016 OSG all-hands meeting was held between Monday, March 14 and Thursday, March 17 at Clemson University in Clemson, SC, thanks in large part to Jim Bottum, the CIO and vice provost… More »

Throughout any given year, the need of the HEP community to consume computing resources is not constant. It follows cycles of peaks and valleys driven by holiday schedules, conference dates and other factors. Because of this, the classical method of provisioning these resources at providing facilities has drawbacks, such as potential over-provisioning. Grid federations like… More »

DCAFI moving forward

The Distributed Computing Access with Federated Identities (DCAFI) project is moving forward on schedule and should be ready to start migrating the first experiment in June. For those of you who are unfamiliar with it, these are the motivations for the project: Dependency on Kerberos makes it difficult for non-Fermilab scientists to access our grid resources remotely, obstructing our lab´s goal… More »

AFS transition

We will be turning off the Fermilab AFS servers in early May this year because the sort of worldwide file sharing once unique to AFS is now provided by the Web. Click here for details of the migration shutdown.

Here are links to pages that were developed by Katherine Lato for ftbf.fnal.gov that give information on things like how to add a user, minor tweaks to the HTML, adding pictures, etc. http://ftbf.fnal.gov/administration/ Another useful source of information is the Using WordPress site at: https://fermipoint.fnal.gov/collaboration/UPP/SitePages/WordPress%20Page.aspx    This is a useful place to record things that you find… More »

New sites for MicroBooNE

The MicroBooNE collaboration operates a 170 ton Liquid Argon Time Projection Chamber (LAr TPC) located on the Booster neutrino beam line at Fermilab. The experiment first started collecting neutrino data in October 2015. MicroBooNE measures low-energy neutrino cross sections and investigates the low-energy excess observed by the MiniBooNE experiment. The detector also serves as a… More »

The Open Science Grid (OSG) has recently achieved a number of milestones and continues to provide distributed grid computing resources to scientists around the world at a record scale. 2015 marked the first year since the OSG’s inception a decade earlier that over 1 billion computational hours were consumed by OSG users.

Carefully tailoring your resource requests will increase your job throughput With partitionable slots now the norm on GPGrid, it’s important to have a good understanding of resource requirements. The memory, disk, and maximum runtime available in free job slots changes as users submit jobs. As a result, there may be free slots that have less… More »

Wondering why your jobs have been put on hold? Want to better set your resource requests to make more efficient use of the grid (and to get your jobs starting faster)? This information, and more, will be available in the FIFE monitoring application, Fifemon, soon, and is already available for testing in pre-production (https://fifemon.fnal.gov/monitor-pp/). Starting… More »

FIFE has a Wiki page to help match resource requirements and availability at remote sites Previous editions of FIFE notes have shown glimpses of the tremendous computing resources available on the Open Science Grid. These resources come from a large number of remote sites, each of which has its own limitations and policies regarding opportunistic… More »
