History q ~1998 the first version of the EF project was defined, but not a lot has happened q end 1999 a new attempt was started to revive the project. ã First meeting (30/11/99) between experiments took place to express their views å There was some agreement between the experiments that IT should provide tools to – Configure and manage large farms (1000 s of CPUs) – Control and monitor the farm operation ã Second meeting took place with IT representations on 4 th February where IT presented their current activities Beat Jost, Cern 3

Description of New Project q Provision of a toolkit covering all aspects of the farm management/control/monitoring : ã infrastructure: remote reset, temperature sensing, network monitoring. . . ã system management: configuration of the system, control of OS of each node, handling non-homogenous systems, . . . ã application management/control/monitoring: Starting applications in a node, monitoring CPU, memory usage, I/O ã interface to the data from monitoring/control. q Testing of new technologies ã Hardware ã Software q Organization of a yearly workshop to share experiences with large farms from present and future high energy physics experiments and from other fields Beat Jost, Cern 4

Our Position Our position vis-à-vis the project is the following ã Software Local to a machine of the farm å We are interested in a set of tools that allow us to – monitor the basic quantities of a machine (CPU, IO, Memory, …) – create/delete processes ã Software to remotely activate the above services ã Integrate the remote access into the SCADA system for controlling the farm processors, but also the processes themselves. Beat Jost, Cern 5

Current IT Activities q LINUX Configurator (ANIS) q Farm Monitoring q CERN’s plans for Farm ‘prototypes’ Beat Jost, Cern 6

Linux Configurator (ANIS) q Basically a database that is accessed by several servers and daemons q Functionality: q Does a complete (re)-installation of Linux on a PC from scratch see http: //home. cern. ch/bosman/anis. ps Beat Jost, Cern 7

Performance and Exception Monitoring q More Computer Center oriented ã neglects “Controls” aspect ã ensures availability and correct functioning of a service q No integration of SCADA system q Not really in the direction we would like to go q Perhaps some things we could eventually re-use see: http: //www. cern. ch/proj-pem/Project/Presentations/PEM_at_EFF. ppt q Actually Clara has made software to connect CPU monitoring to a SCADA system Beat Jost, Cern 8

Farm Testbed q IT is going to setup a testbed for CPU farms q The idea is that parts or all of it can be reserved for a some time for test purposes Beat Jost, Cern 10
