Technical Requirements and Features what do we offer to help HEP ComputingCHEP 2000Resource Management with CODINE / GRDGridware - The Company Technology Leader in Resource ManagementA special offer to the HEP community Our answer to falling hardware-prices

Technical Requirements and Features Array Jobs Advanced Queue Concept Policy Management Separation of Components Solutions for mixing interactive and batch Simplified system administration AFS Support CORBA Interface All classic Features Availability
-
Array Jobs#!/bin/sh...1 single Submit-Command for thousands of similar jobsExample: qsub -t 1-1000:1 jobscript.sh
creates 1000 instances of a single job The whole array can be (also partly) manipulated (deleted, suspended, ...) with 1 command unlimited number of instances
-
Job
Advanced Queue Concept The whole cluster can be adressed Soft requests are supported No empty queues while others are more than full each host can be treated with different policies users just request resourceshigher efficiency Emergency Room ConceptJobClusterDispatchJobQ1Q2Example: qsub -l mem_free=10M jobscript.sh Cluster is split Queues may run empty users have to decide for a queue Job has to stay in line also if other resources are unusedGrocery Store ConceptExample: qsub -q 10MQ jobscript.sh

-
Separation of Master and Scheduler Scalability high performance good response time faster job placement
Separation of Components
-
Simplified system administration No daemon restarts necessary Add machines on the fly Ability to install the entire cluster from one workstation No submit daemons or configuration needed for client Optimized architecture provides reliabilityConifiguration changes without any pain
-
What else?CORBA InterfaceAFS Support All classic FeaturesInteractive vs. Batch accounting, monitoring, suspension, sensors ... time windows automatic suspend migration, ...Availability all leading unix platforms

Range2 - 4 CpusSoftware has to support rangesCodine supports ranges
Restart, Job grows or keeps same amount Auf CPUsMake sure that the job does not fail:
at start-up and monitoring while running
Get shorter Response Times:
waiting for scheduler, then faster job-run;overall: more jobs in the same time-period
