Setting up a floating license for Arm Allinea Studio

Before you begin

  • To use floating licenses, you must download and install Arm License Server on the designated license server machine.
  • A floating license consists of a server license file and a client license file. If you do not already have these files, request a valid license here.
  • Check that the client license contains the host name or IP address of the machine running the Arm Licence Server.


  1. Add the client license to the machine where Arm Allinea Studio is installed. Create a directory called licenses in the /opt/arm directory.
  2. Copy your license file to /opt/arm/licenses.
    Note: If you choose to put the license file in a different location, you must set the ARM_HPC_COMPILER_LICENSE_SEARCH_PATH environment variable to point to it. See Changing the license file location.
  3. Arm Forge and Arm Performance Reports search for individual licenses in their specific installation directories. If you do not have separate license files for Forge and Performance Reports, you must set the ARM_LICENSE_DIR environment variable to point these tools to your Arm Allinea Studio license.
    export ARM_LICENSE_DIR=/opt/arm/licenses
    Note: The ALLINEA_LICENSE_DIR environment variable is still supported alongside the ARM_LICENSE_DIR environment variable.
  4. Add the server license file to the machine where Arm Licence Server is installed. Create a directory called licenses in the /opt/arm/licenceserver directory and copy your license file to it.
  5. Restart Arm Licence Server to enable it to detect the new floating license.
