We will need to prepare a temporary license for your cluster.
Download the applicable Linux binary, unpack it, and source adfbashrc.sh e.g.

cd
tar -xf adf2019.304.pc64_linux.intelmpi.bin.tgz
source ~/adf2019.304/adfbashrc.sh

Then run

$ADFBIN/dirac info

On the head node and the compute nodes (make sure you have sourced the adfbashrc.sh first when running on the compute nodes).
Send the output for all machines as plain text text to adftrials@scm.com so we can generate a demo license for your cluster.

For each machine the info should look something like

SCM User ID:
release: 2019.305
:scm.com:
:Linux42.thgttg.comDC:3F:2B:C2:41:3C:
:ncores 48:
:CPU Model AMD EPYC 7402 24-Core Processor:
:DMY 29- 9-2020:
:SRCID 5481197:
LICENSE FILE NOT FOUND

If the environment is not set automatically by sourcing the adfbashrc.sh, you may need to edit it. See also the installation guide. Contact support@scm.com with any problems, being specific about what you tried and where you run into problems.

This can be for various reasons.

Most commonly it’s because your firewall does not allow automatic download of the license (Problem contacting the SCM license server). Please send us the license error you get as plain text to adftrials@scm.com so we can manually generate a license.

Other common reasons are: you exceeded the maximum number of machines for your trial (contact adftrials@scm.com to enable more), your license period expired, or the machine is active in an other account.

List of most occurring messages and actions to be taken.
In all cases, when in doubt, send an email to license@scm.com with your userid and the exact error output as plain text. Also let us know in case where we should get back in a few days, but we didn’t.

  • Automatic download of your license is not allowed in your account => The SCM team will check if it should be allowed
  • License request submitted => The SCM team will check
  • Your ADF license has expired => consider license options
  • Your license period has expired => consider license options
  • Automatic download of your license has been refused (….). Your credentials for this license are disabled. => contact us if you believe this is in error
  • Your license request has been refused, because the number of allowed licensed machines has reached the maximum. => contact us to discuss to increase the number of allowed machines
  • We will check your license request => SCM will check
  • We will process your license request manually => SCM will check
  • Your request is submitted to SCM and will be processed within a few working days => SCM will check
  • Your account does not allow automatic download of your license => SCM will check

Please send an email to license@scm.com with your userid and a the full error output as plain text.

Floating licenses can be used on Linux clusters. With a floating license, only a certain amount of cores can be used at the same time for a certain module in the Amsterdam Modeling Suite. For the license fees, floating cores are counted double with respect to host-locked cores.

To set up a floating license, you need a centrally accessible directory in which all AMS users have write permissions. The installation manual explains how to do that and generate the necessary information.

If you have a valid username and password (your evaluation period is still active or you are a current AMS licensee), you should be able to download AMS with the provided password and username.

The browser could have cached the wrong password from a previous attempt. Try again with a private session. Make sure you don’t include any spaces, the username is usually 6 characters and the automatically generated password is exactly 8 characters. If you still have problems, contact us at license@scm.com with the username and password and the download link for the binary you tried to download.

Download the correct binary, usually the standard Linux binary will do. Follow the quickstart guide and let us know at support@scm.com if you run into any problems.
You should be able to automatically download a demo license. If your machine does not have an internet connection, run

$ADFBIN/dirac

which should give you a LICENSE INVALID message and your machine info. Please send this as plain text text to adftrials@scm.com to request a demo license for your machine.

The AMS installer sets the necessary environment variables in the Windows registry and notifies Explorer, but sometimes the latter does not work. In that case if you try to pick up your automatic demo license, you get the error message about the SCMLICENSE not being set.

If you reboot your system, the SCMLICENSE variable should be properly set and with your credentials you can then automatically download your demo license.

No. Starting with AMS2018, all licensed machines include the GUI and the AMS driver.

Yes, since AMS2018 we work with module points. If you have 4 module points or more you can get the whole AMS bundle. You can always request a detailed price quote.

Not for a host-locked license. In such a case one should use a 16-core license, or select an 8-core machine to install AMS on.

You can start immediately. After we have received your informal purchase order confirmation, your signed license agreement, and your machine information, you will receive a temporary license until the invoice is paid.

In case of any type of license upgrade, we will only charge price differences and only for the remaining time period of the contract, thus making it easy and attractive to upgrade.

For multi-year licenses we can change the machine info once a year when we send a new license file for the next year. Certain exceptions are possible at SCM’s discretion.
You can of course always upgrade your license to include more CPU cores.
