The Metadispatcher: the implementation by Globus Metacomputing Infrastructure Toolkit

The Metadispatcher implementation by Globus Metacomputing Infrastructure Toolkit is proposed. The Metadispatcher is job management system at heterogeneous computational Grid. The Grid jointes several computer groups. Every computer group is managed by some Batch Management System. Globus toolkits review is presented. Functonality and architecture of the Metadispatcher are described, including jobs spool, command interpretator, sheduler and job monitor. A problem of job preparation is considered taking the heterogeneity.
