  2. Introduction Architecture Features BQS tools BQS in numbers Outlines

  3. CC IN2P3 batch scheduler since 1991 Home made product because of The VM to Unix migration No solution offering the level of functionality needed Developed by Yves Fouilhe (fouilhe@cc.in2p3.fr) Source code free Unix flavor Introduction

  4. BQS Architecture Scheduling parameters Global Resources parameters Farm Master Resources Plateform Status etc. Worker Worker Workpoint Workpoint Workpoint classes ordered list

  5. Workpoint : Used to get a better control over job production; Defined as a set of orderedclasses allocated to a worker; Runs only one job at a time, but Multiple workpoints on a worker. Example : workpoints definition for ccwasn01 (two processors SUN worker) 1@ccwasn01.in2p3.fr : T,S 2@ccwasn01.in2p3.fr : G,C,A 3@ccwasn01.in2p3.fr : I,R,J,P 4@ccwasn01.in2p3.fr : S,T,I,R Up to 4 jobs can run at the same time for the ccwasn01 worker. About 900 workpoints at the IN2P3 Computer Center. Workpoint Definition

  6. Class Definition

  7. Multiple AFS token support Group & user scheduling policies Resource management (CPU, memory, disk) Distributed environment (authentication service, privilege management and directory service made by internal products) Command line, API and graphical interfaces (JBQS) Features

  8. A set of commands for users submitting jobs (qsub) tracking tools (qjob, qcat qalter, qaccount, qdel, qrerun) Administration tools (JBQS) Batch management BQS administration Statistic and accounting tools BQS Tools

  9. Available on 4 different platforms (Solaris , LINUX, AIX, HP-UX) 250 workers (355 CPU) 900 workpoints 2000 accounts BQS in Numbers
