SA1 ROC Meeting Bologna, October 2004 Priorities for grid operations Bob Jones EGEE Technical Director EGEE is a project co-funded by the European Commission under contract INFSO-RI
2
Priorities for grid operations
Succeed in passing the 1st EU review (Feb ) by demonstrating that we have established a large-scale production quality grid infrastructure supporting multiple applications and user communities The active involvement of the ROCs is essential to meet this goal From Tech Annex: “In terms of funding and manpower, the ROCs represent the single biggest item in the EGEE proposal” ROC managers, Bologna, October
3
Specific goals for grid operations
Deployment and support of non-HEP applications Continued support for HEP data challenges Complete migration from LCG to EGEE operations structure Continued expansion of the production service Deployment of pre-production service providing early access to gLite components for applications EU review will include live demonstrations of HEP and BioMedical applications running on the production service. gLite will also be demonstrated. ROC managers, Bologna, October

Resources for non-HEP applications
Resources needed for non-HEP applications thru end 2004: BioMedical: GATE 100 CPUs, several tens of GB storage and access to a supercomputer (CINES Montpellier) NPSA ( CPUs: 10 sites with 10 CPUs each and short queues. IO file size: from kB to GB. file storage: 500 GB Drug discovery CPU usage: 4 150 h, input file size: 10 MB, output file size: 1-2 MB, number of jobs: Generic: Earth Observation Storage Elements: 500GByte, distributed over several Centers Computing Elements: Cluster with fast connection like Mirinet to run IPGP MPI jobs Total computer time predicted to be used is around hours Astroparticle physics 200 CPUs and 5TByte of storage Earth Science Up to 100 CPUs and 100Gbyte of storage Computational chemistry 128 nodes + 16 CPUs with at least 2GB of RAM Provision of missing month 1 resources would cover most of these requests ROC managers, Bologna, October

Resource Negotiation Via the PMB, the federations have been asked to:
Provide a statement about national policy for the allocation of resources. Example: “African federation: in Nigeria we will provide resources connected to EGEE for applications from HEP (90%), Biomedical (5%), computational chemistry (3%), earth observation (2%). In Benin we will provide resources for applications from Biomedical (50%), astrophysics (30%), geophysics (20%), etc.” Empower ROC managers to use this information as a guideline when negotiating resource allocation with participating sites ROC managers, Bologna, October

Relationship with CICs
Proposed CIC agreement Each of the CICs (RAL, CNAF, Lyon, CERN) assigns people to operations management, with responsibility cycling round the sites on a weekly basis daily run of the validation test suites monitoring the roll-out list, filtering out problems overview of the general availability and performance monitors based on the results of the above - generation of trouble tickets lead the investigation of difficult problems active management/escalation of trouble tickets intervention as necessary with ROCs/primary sites assembly of FAQs, recipes and other useful documentation proposing and developing additional tests, automating processes, etc. The CICs would normally communicate with the ROC/Tier-1/Primary Site, which is in turn responsible for taking action directly with the site. Where there is no appropriate ROC or Tier-1 a "Primary Site" will be assigned (usually one per country) ROC managers, Bologna, October
