Grid Based Monitoring on the Rutgers CDF Analysis Farm
نویسندگان
چکیده
Run II at the Fermilab Tevatron Collider started in March 2001, and it will continue probing the high energy frontier in particle physics until the start of the LHC at CERN. The CDF collaboration at Fermilab has already stored 260 TB of data and expects to store 1PB of data in the next two years. The HEXCAF computing farm is being set up at Rutgers University to provide the software environment, computing resources, and access to data for physicists participating in the Collaboration. Some job submission, detector data access and storage of the output results are based on the SAM-GRID tools. To extend monitoring for these jobs running on the farm a bridge was developed between the SAM-GRID monitoring tools and the internal farm monitoring. This presentation will describe the configuration and functionality of the HEXCAF farm with the emphasis on the monitoring tools. Finally we summarize our experience of installing and operating a GRID environment on a remote cluster that is being used for real physics studies in the big running experiment.

متن کاملDamping analysis of sub-synchronous resonance (SSR) in a wind farm based on DFIG in a series compensated network
The effect of wind generator on sub-synchronous resonance (SSR) is being interested by increasing penetration of wind turbine in power systems,. Purpose of this article is to analyze SSR in a wind farm based on doubly fed induction generator (DFIG) which is connected to compensating series grid. A dynamic model for analysis of induction generator effect and Torsional Interaction (TI) has been u...
متن کاملUsing SAM datahandling in processing large data volumes
SAM is the new, grid enabled datahandling system of the CDF experiment at Fermilab. Its core capabilities are storing metadata and locations for data files and transferring the files to the nodes to process them. The system is known to work for physics analysis jobs. To accommodate the compute needs for physics analysis jobs, CDF introduced the CAF batch farm system. Now SAM and CAF are used to...
متن کاملA New Method to Study Aggregation Effect of Harmonic Current Emissions in a Wind Farm Based on Type-III Wind Turbine Average Modeling
Assessment of complex harmonic current contribution of each wind turbines at connection point of a wind farm to the grid (primary emission) is presented in this paper. Moreover, contribution of grid background harmonic voltage distortion on harmonic current distortion (secondary emission) of each turbine is also evaluated. Both assessments are represented based on primary and secondary transfer...
متن کاملCoordinated Control Strategy for a Hybrid Wind Farm with DFIG and PMSG under Symmetrical Grid Faults
This paper presents a coordinated control strategy for a hybrid wind farm with doubly-fed induction generator (DFIG)and direct-driven permanent-magnet synchronous generator (PMSG)-based wind turbines under symmetrical grid faults. The proposed low-voltage ride-through (LVRT) strategy is based on a novel current allocation principle and is implemented for individual DFIGor PMSG-based wind turbin...
