Basic tasks in Accelerator, including submitting jobs, tracking job information, and analyzing and solving common problems.
Accelerator documentation is available in HTML and PDF format.
Accelerator has two main commands, nc and ncmgr.
In Accelerator, each job goes through a number of states until completion.
An important feature of Accelerator is job persistence. After a job completes, its information remains in vovserver's memory until the job is forgotten, manually or automatically.
The autoforget flag sets up a job to automatically be forgotten by the system after a certain time, (not including suspension time) if and only if the job is done, failed, or idle. Jobs that are scheduled, running, suspended or transfer are never autoforgotten.
The scheduling process controls the order of job execution.
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.
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.
