This daemon vovfilerd replaces older daemons like vovisilond, vovnetappd and vovregulatord. Also the utility vovfiler_setup is no longer needed. The visualization of the filer information is now done either via the vovfilerd.cgi page or via the utility vovfilerdgui.
Accelerator stores historical information about jobs in a relational database. As of version 2015.09, the database is fully integrated and managed as part of Accelerator. This section provides an overview of the components that run and manage the database.
Preemption is the process of reserving or revoking resources from other jobs in order to help "important jobs" finish quickly.
Preemption plans are the building blocks of preemption methods and allow the implementation of custom, complex multi-step preemption sequences.
The Accelerator web interface provides a form-based method of entering preemption rules and methods, and viewing statistics regarding the activation of previously entered preemption rules.
The preemption subsystem has a complex behavior, controlled by many delays that are described in this section.
Manual preemption can be used in addition to or instead of automatic preemption.
Altair Accelerator includes a subsystem for managing computing resources. This allows the design team to factor in various constraints regarding hardware and software resources, as well as site policy constraints.
To ensure the correct and repeatable behavior of the tools, the environment must be controlled. This chapter explains how VOV supports multiple reusable environments.
If a server crashes suddenly, VOV has the capability to start a replacement server on a pre-selected host. This capability requires that the pre-selected host is configured as a failover server.
This section provides instructions to change the software version on which Accelerator runs.
This chapter provides information about deprecated features that are still supported. This information is provided should you see older commands in use after a software upgrade or migrating to a newer Accelerator.
