2015 OSG User School Accessing an OSG Submit Point – 4 Ways Local Virtual Organization (VO)  campus, national lab, or research organization that is part of the OSG consortium OSG Connect  an OSG VO for individuals without a local VO  OSG Connect Client  use another cluster submit/head node as an OSG submit point XSEDE  collection of HPC clusters available to U.S. academics via allocations of compute hours 10

2015 OSG User School *not all XSEDE Campus Champions will have experience with HTC or OSG Accessing an OSG Submit Point – 4 Ways 13 Local VOOSG ConnectConnect ClientXSEDE Available to users with a campus/org VO affiliates of U.S. research orgs users of cluster with Connect Client users with XSEDE allocation Cost unlikelyFREEunlikely NO (but need allocation) Limit on CPU hrs unlikelyNO YES (per allocation) Local Help very likely (local staff) unlikely possibly (cluster staff) possibly* (Campus Champion) Online Guides likelyYES limited Submit Point Type submit server (or direct OSG entry server) direct OSG entry server cluster submit node to OSG entry server submit node to OSG entry server

2015 OSG User School Accessing an OSG Submit Point – 4 Ways Local Virtual Organization (VO)  campus, national lab, or research organization that is part of the OSG consortium OSG Connect  an OSG VO for individuals without local OSG support  OSG Connect Client  use another cluster submit server as a submit point XSEDE  collection of HPC clusters available to U.S. academics via allocations of compute hours 14

2015 OSG User School Virtual Organization (VO) institution or research project that is part of the OSG consortium accounts and access determined by local VO administrators most offer user support or specialized interfaces for their specific setup and population of users How do I determine whether my organization is/has a VO? 15

2015 OSG User School Using OSG through a VO 1.Determine whether there is a local VO for your institution/organization. 2.Get an account Contact the administrators to get an account on their glidein server (or submit node tied to a glidein server). 3.Submit jobs Follow site-specific guides and/or submit jobs as you have been at the OSG School. 20

2015 OSG User School OSG Connect 22 Essentially, a VO available to those without a Local VO Free for affiliates/partners of U.S. research institutions Submit from OSG Connect server or use Connect Client on another cluster OSG ConnectBook has online guide information and contact info for help

2015 OSG User School OSG via 26 XSEDE: a consortium of HPC clusters and other computational services available to academics in the U.S. free accounts, but you must request an XSEDE allocation of compute hours limited online guides specific to OSG- XSEDE, but similar to submission via osg-ss-glidein-submit

2015 OSG User School Using OSG via 27 1.Sign up for an XSEDE account. 2.Request an OSG allocation via the XSEDE User Portal to request a startup (or long-term) allocation of compute hours for OSG. 3.Follow XSEDE’s guides for connecting to and using the OSG submit server. 4.Submit jobs as you have been at the school, making sure to indicate your XSEDE project name (allocation code).
