Altair License Management

This is a Quick Reference Guide covering how to install, set up and manage your licenses keys using the Altair License Management system (ALM). ALM is derived from LM-X License Manager from X-Formation.

Getting Started with Altair Licensing

In Accelerator product versions 2023.1.0 and later, Altair Licensing is activated by default. If upgrading from a Reprise-based license for FlowTracer and seat-based licensing is being utilized, the name of the seat-based license will need to be changed to an Altair Licensing feature name. See Licensing FlowTracer by Seat.

For a standalone license file situation, set ALTAIR_LICENSE_PATH to the pathname of the license file. For floating license usage, set ALTAIR_LICENSE_PATH to “PORT@HOST” for the ALM license server.

The I/O job profiling feature enables Accelerator to track and plot performance statistics over the time the job is running. This feature can only be activated with a Mistral license, which must be installed at $VOVDIR/local/mistral.dat. Check with your system administrator for accessing and installing the license.

The following sections will describe procedures for managing floating ALM licenses and the ALM license server.
