LTU Site Report Dick Greenwood 16sep05 4 CAPS CLUSTER

LTU Site Report Dick Greenwood 16sep05 5 D0SAR MC Delivery Stat. (as of 3/28) InstitutionInceptionN MC (TMB) x10 6 LTU6/ Presently running a 200,000 event request. Still changing to SamGrid/Runjob

LTU Site Report Dick Greenwood 16sep05 6 LTU Plans “Small” site should continue taking MC production requests Participate in the development of the Louisiana Optical Network Initiative (LONI) with its 10GB/sec connectivity to the National Lambda Rail. The NLR POP in Baton Rouge has not been affected (the route runs from Baton Rouge to Houston). The core routers will be delivered to each campus as soon as they are ready. The awarding of the local loops seems to be the bottleneck with all of the purchasing/bid requirements. HSC-NO data center is located at the Public Safety office (BR?) Tulane data center is located in Houston. UNO data center is at LSU.

LTU Site Report Dick Greenwood 16sep05 7 Status of CAPS Site Caps: Mostly recovered from (premature) installation sam v6 products. Had to retailor all samgrid products. Had issue (again) with disks declared as INACTIVE. Problem had to do with mixed case nature of domain name(Latech.edu vice latech.edu) Found workaround to this problem by digging into the Samshifter FAQ's. At present I am about finished getting an upgrade to condor installed on all machines (windy’s still not done). Also recovering from loss of an /apps/ disk

LTU Site Report Dick Greenwood 16sep05 8 Status of SuperMike Site LTU (at supermike). Will use on machine with sam station and gatekeeper combined. Installed an additional 200 G on this machine last month. Still a work in progress.
