Gurobi license issue on Baobab and Yggdrasil [urgent help needed!]

Hi everyone,

There is an issue again with the Gurobi license. It works on the login node but not on the other nodes.

[sasse@login2.baobab ~]$ module purge
[sasse@login2.baobab ~]$ module load Gurobi
[sasse@login2.baobab ~]$ gurobi_cl --tokens
Checking status of Gurobi token server ‘master.baobab.hpc.unige.ch’…

[sasse@node001.baobab ~]$ module purge
[sasse@node001.baobab ~]$ module load Gurobi
[sasse@node001.baobab ~]$ gurobi_cl --tokens
Failed to connect to token server ‘master.baobab.hpc.unige.ch’ (port 41954).
Problem retrieving token server status

Is there a fix for this? We unfortunately need urgent help, because we need to finish the runs by the end of the week.

Best, Jan

Hi,

I’ll check the issue, this is probably because we forgot to move the license server to the new admin server.

thanks! have you found the issue?

Hi,

I’ve installed a new version which solve the issue: New software installed Gurobi 9.5

For the old version:

You should set this variable after loading the Gurobi module:

[sagon@node001 ~] $ module load Gurobi/8.1.1
[sagon@node001 ~] $ GRB_LICENSE_FILE=/opt/ebsofts/licenses/Gurobi/gurobi.lic
[sagon@node001 ~] $ gurobi_cl --tokens

Checking status of Gurobi token server 'master'...

Token server functioning normally.
Maximum allowed uses: 4096, current: 0

thanks it works now!

Hi,

The Gurobi license is not available anymore. Both for the new 9.5 Gurobi version and the old 8.1.1 Gurobi version.

Here you can see that it doesn’t work for Gurobi 9.5

ml Gurobi/9.5.0
gurobi_cl --tokens
Failed to connect to token server ‘admin1.baobab’ (port 41954, timeout 30).

Here you can see that it doesn’t work for Gurobi 8.5.1

module load Gurobi/8.1.1
GRB_LICENSE_FILE=/opt/ebsofts/licenses/Gurobi/gurobi.lic
gurobi_cl --tokens

Hi, it is restored.

Best
