The OSG relies on external project collaborations to develop the software to be included in the VDT and deployed on OSG. Our collaborations are continuing with: Community Driven Improvement of Globus Software (CDIGS), SciDAC-2 Center for Enabling Distributed Petascale Science (CEDPS), Condor, dCache collaboration, Data Intensive Science University Network (DISUN), Energy Sciences Network (ESNet), Internet2, National LambdaRail (NLR), BNL/FNAL Joint Authorization project, LIGO Physics at the Information Frontier, Fermilab Gratia Accounting, SDM project at LBNL (BeStMan), SLAC Xrootd, Pegasus at ISI, U.S. LHC software and computing.
OSG also has close working arrangements with “Satellite” projects, defined as independent projects contributing to the OSG roadmap, with collaboration at the leadership level. Four new satellite projects are:
-
High Throughput Parallel Computing (HTPC) on OSG resources for an emerging class of applications where large ensembles (hundreds to thousands) of modestly parallel (4- to ~64- way) jobs.
-
Application testing over the ESNETESnet 100-Gigabit network prototype, using, using the storage and compute end-points supplied by the Magellan cloud computing at ANL and NERSC.
-
CorralWMS to enable user access to provisioned resources and “just-in-time” available resources for a single workload integrate and build on previous work on OSG's GlideinWMS and Corral, a provisioning tool used to complement the Pegasus WMS used on TeraGrid.
-
VOSS: “Delegating Organizational Work to Virtual Organization Technologies: Beyond the Communications Paradigm” (OCI funded, NSF 0838383)
The European EGEE infrastructure will transition to several separate projects in March 2010. OSG has been active in talking to the new leadership to ensure a smooth transition that does not impact our stakeholders. We have several joint EGEE-OSG-WLCG technical meetings a year. At the last one in December 2009 the following list of existing contact points/activities was revisiting in the light of organizational changes:
Continue within EGI-InSPIRE. The EGI Helpdesk (previously GGUS) will continue being run by the same team.
-
Grid Operations Center Ticketingticketing systems interfaces.
-
Security Incident Response.
-
Joint Monitoring Group (MyOSG, MyEGEE). MyEGI development undertaken by CERN (on behalf of EGI-InSPIRE) will establish relationship with IU.
