Service name: Workload Manager (DIRAC)

Introduction

EGI Workload manager (previously known as DIRAC4EGI) is a service provided to the EGI community as a workload management service used to distribute the users' computing tasks among the available resources both HTC and cloud.

The Workload Manager is based on DIRAC technology and is suitable for users that need to exploit distributed resources in a transparent way. The service has a user-friendly interface and also allows easy extensions for the needs of specific applications via APIs.

Technical description

The Workload Manager service is a cluster of instances to allow the users to submit computational tasks to the HTC and Cloud services, monitor the status and retrieve the results. Users interact with it both using GUI and API.

The components of the DIRAC service are:

  • DIRAC WMS server (multiple high performance machines)
  • DIRAC DB (MySQL) server (high performance, large memory machine)
  • DIRAC REST server (medium sized machine)
  • DIRAC Web server (low CPU, high memory machine)
  • DIRAC configuration server (low CPU, high memory machine)
  • DIRAC data manager service (low CPU, high memory machine)
