- Command Line Interface
  - CLI Commands
    The Altair Accelerator products have a rich set of programs that can be run the shell command line. Each program performs a specific task and is controlled by a set of command line parameters. The programs provide a usage command when run with an -h parameter as a quick way to understand what each does and what parameters it takes.
  - VOV Properties
    Properties can be attached to any object in the vovserver. Properties are managed from the command line via the vovprop command. This command can get, set, delete, and show properties on objects.
  - Customization of Node.cgi
  - vovshowconnection
    Show connection between two nodes in the trace.
  - vovwavepp
    The utility vovwavepp is used to convert the verbose logs generated by the vovserver into efficient "wave" files.
  - vovmemtime
    vovmemtime is a utility to create simulated workloads. When this program runs, it occupies a specified amount of memory and creates high CPU utilization for the requested amount of time, to simulate the activity of real design programs running.
  - vovtestsocket
    Test vovserver socket connectivity.
- Fields, Selection Rules and Formatting Strings
- VOV Metrics
  The Altair Accelerator allows users to collect arbitrary metrics, where a metric is defined as a "named time series" of values, where each value is either a floating point number or a string.
- Miscellaneous
- VOV Security Infrastructure
- REST Application Programming Interface
  Altair Accelerator supports a RESTful API that enables a developer to submit, monitor, and control batch jobs as well as query the batch scheduler queues, jobs, and hosts in useful ways.

Customization of Node.cgi

The node.cgi script can be customized by means of these properties:

DESCRIPTION

This property must be attached to the node to be displayed. It consists of a string that is displayed in the Job Description section of the page. This property may go away because it is redundant with the job name field.

FIRENOW_RESOURCES

If this property is defined in object with VovId=1 (the VovTrace), it represents a resource expression for a job. This property activates the "FireNow!" capability in node.cgi. The

icons appears in the top right corner and if clicked, it causes the resources for the job to be replaced with

( @FIRENOW_RESOURCES@ ) OR ( @ORIGINAL_RESOURCES@ )

and the job is rescheduled at top priority. This assumes that there are taskers that offer the resource "@FIRENOW_RESOURCES@" A typical example of use of this property is

% vovprop set 1 FIRENOW_RESOURCES "fireNow"

NODE_CGI_OUTPUT_SUMMARY

This property must be attached to the trace object (VovId=1). It consists of a space-separated list of glob expressions. If an output file matches the glob expression, it will be displayed in the page. (See also OUTPUT_SUMMARY below.)

OUTPUT_SUMMARY

This property must be attached to the node to be displayed. It consists of a space-separated list of glob expressions. If an output file matches the glob expression, it will be displayed in the page.
