We realized there was a need for a Ethernet manual that explains FLEX lm from an end-user standpoint. This manual grew out of that need and is provided as a service to you, the end-user. Keep in mind that certain topics such as password encryption are vendor-specific and proprietary so we cannot document them in any detail. Also, because FLEX lm does not enforce a particular licensing strategy, each vendor's implementation can have subtle differences.

This uses Flexera Flexlm version The release of Intel Parallel Studio and its components require the license server manager to be at Flexlm version Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors.

Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.

Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice. Safari Chrome Edge Firefox. See the Release Notes for supported OS versions. Please refer to the installation section to setup the shared library if it is not in place on your system. The floating license is used in multiple-user environments, and the.

The essential components of the sample license file are listed below along with their corresponding values:. Note: While host name and port numbers can be changed, editing many parts of the license file renders the entire license file invalid. References to IA architecture platforms are for legacy purposes only. Please make sure to download the latest ISL Manager when you upgrade to a newer product version.

The older ISL manager will not support newer product version. Registering the license links it to you, but does not associate it with a particular server until you activate it.

If you have not registered your license, you may do so in the Intel Registration Center by following the steps in this guide: Steps to register a floating license. You may also activate your license at this time if your license server is not connected to the internet for remote activation. It is important that you have the latest version. The license can be configured to use different ports and change other settings.

The Intel Software License Manager installer will automatically activate a license with default settings if it has internet connectivity. If your license server does not have connectivity, you can manually activate the license in the Intel Registration Center. Activation requires the host name and host ID of the server s to be serving the license.

It is strongly recommended that you run the lmhostid utility to obtain the hostid value it will use for license validation. If you have not installed the license manager, use the instructions below to find the host name and host ID of the system.

If multiple IDs are displayed, choose the one associated with eth0. If the host name command returns a fully qualified domain name, you must use it to configure the license.

In the resulting output, host name is the value that corresponds to Host Name, and host ID is the value that corresponds to Physical Address. Note, the host ID will be entered without the dash character. There are several settings you can change in the Intel Registration Center to configure your license file. The license manager uses two ports — one for each daemon it runs.

Both of these ports MUST be open and unblocked. See the OS vendor documentation for more information on adding port exception to the system firewall. This is the primary daemon for the license manager. It listens for license checkout requests and routes them to the correct vendor daemon. This can be changed in the Intel Registration Center. This is the daemon used to serve licenses for Intel developer products. It can be specified in the license file, or assigned by the OS each time lmgrd is started.

To prevent the INTEL port from changing at lmgrd startup and potentially being blocked by a firewall, it is recommended to specify this port in the license file. This requires the use of three servers defined in the license file, two of which must be active to serve licenses. License borrowing allows users to hold a license seat for a limited amount of time, such as when working offline. This will completely consume a license seat until it is returned to the server.

It will also include the maximum borrow time, which is defaulted to hours. To change the maximum borrow time, or disable licensing borrowing, you must contact support to get a new license file generated.

It is important that the network has been initialized before the license server is started. It is not necessary for server startup be done as root. Use the full path to the license file, including the full license file name.

Use the full path where the log file should be created, including the log file filename. Essentially, the first two lines or four for redundant server set-up of the license files must match. The preferred method of serving multiple licenses is to use separate files. Although the license manager installer only accepts a single serial number or license file, you can restart it with the path to a folder containing multiple license files to serve them all.

All licenses should use file extension. To start the license manager with a folder path, either:. You can combine multiple licenses into a single file.

This is recommended if you want to ensure the order in which the licenses are used, such as serving the more restrictive licenses first. However, you need to take care in modifying the license file as to not invalidate it. To combine license files, use a text editor to open the first license file. The Intel Software License Manager for Windows package has a few utilities for configuration and status checks.

This value is defaulted to the license entered during the license manager installation. This log file must have write permission for the user starting the license manager. From this utility you can view the system settings, start and stop the license manager, reread the license file, check the license server status, configure the paths used by the license manager, and configure the borrowing capability. It requires administrator privileges.

This tab displays the host settings used to verify the server license. From this tab you can start, stop, or reread the license file.

It will display the number of total license seats for each component and the number currently checked out. This is the location of the primary license manager process. This is the path to the license file read by the license manager. It is important to make sure this path only contains valid server license files. The license manager writes all output to this debug log file, including start-up, status checks, and license checkouts. It is created automatically when lmgrd is started.

The user starting the license manager must have write privileges for this file — lmgrd will not use administrator privileges even if the user has them. If the user launching lmgrd does not have write access to this file, they may get an error stating that the license is invalid. Check this box to automatically start the license manager service at system start-up.

It is only enabled if the Use Services box is also checked. Use this tab to manage license borrowing. Lmgrd is the primary process for the Intel Software License Manager. To run it manually through the command-line:. It can be run manually as an administrator in the command-line.

These actions must be run in the command-line using two utilities. The lmgrd process launches the license manager for a given license file or folder. This is the daemon provided by FlexNet to serve licenses for multiple vendors.

The settings used by lmgrd are determined by the license file s :. If using a folder, the license files must contain extension.

Both the —c and —l arguments are optional. If the log file is not specified, then all output will be written to stdout. To restrict access to license manager utilities, the following options may be added to the lmgrd command:. If root is not a member of this group, then root does not have permission to use any of the above utilities. Disallow the lmdown command for all users. Lmhostid provides the host ID s used to validate the license file. One and only one of the host IDs listed should be provided during activation of the license, and listed in the license file next to the host name.

Lmreread rereads the license file. Lmremove releases a license seat from a particular user. Use this command if a user is unable to return the seat to the license pool, such as due to a system crash. First, run lmstat —a to determine the feature name, user name, and host name, such as:. The license file would be in the following format:. This can be done through the product installer or manually. Using the full server license file is not recommended. It must match the one used by the license server exactly.
