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.
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.
This is a usage guide for the Resource Data Service (RDS), an alternative service for managing License resources and License-first scheduling in Accelerator.
The Streaming Data Service (SDS) publishes a time series data stream that can be consumed by existing Kafka systems and compatible reporting tools to monitor VOV projects.
To ensure the correct and repeatable behavior of the tools, the environment must be controlled. This chapter explains how VOV supports multiple reusable environments.
The vovnotifyd daemon is used to deliver notifications to selected recipients about functions that are related to job events.
Use the config.tcl file to set the email addresses to be used for each user.
The vovnotifyd command runs in the vovsh binary, so all the VTK API procedures are available to you.

If SMTP is not available, a mailer program could be used instead.
The Accelerator vovnotifyd notification daemon accesses the server's event stream and then sends a notification for jobs that request it.
The daemon vovtriggerd taps the event stream and executes commands that are based on selected events.
VOV issues an "alert" when an event requires attention. An alert can range from information that does not require action to an urgent fault that requires immediate action.
This section provides instructions to change the software version on which Accelerator runs.
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.
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.
