A researcher at Robert Morris University is trying to run 

LS-DYNA (ls-dyna_mpp_d_R12_1_0_x64_centos78_ifort160_avx2_intelmpi-2018) on our RHEL 8.8 cluster (bridges2.psc.edu) at the Pittsburgh Supercomputing Center (PSC) while checking a license off their Robert Morris University (RMU) license server - the server is here: 27014@acadlms03.ad.rmu.edu.  

 

We verified we can contact the license server from the Bridges2.psc.edu cluster  at PSC and can query it, e.g.:

 

$ /opt/packages/ansys/shared_files/licensing/linx64/lmutil lmstat -c 27014@acadlms03.ad.rmu.edu -a

and it reports 0 licenses in use for many features including dyna.  We can access the license server from the compute nodes in the cluster.

 

But, we are not getting LS-DYNA to talk to the license server. We tried setting (bash shell):

   

   export LSTC_LICENSE=network
   export LSTC_LICENSE_SERVER=27014@acadlms03.ad.rmu.edu

 

and running LS-DYna with:

 
$  mpirun -np 1 ./ls-dyna_mpp_d_R10_2_0_x64_centos65_ifort160_avx2_intelmpi-2018 i=Main_ALE_Boundary_Controls.k memory=500m

 

but we get the error message:

 

 License option : check network license only

      Date: 01/29/2024      Time: 12:16:58  

 *** License problem ***
 Network license:

 *** Error License client cannot find any servers to talk to.

               Servers may be down, not ready, or the wrong version.

 

Is there a set of ports beyond obvious one (27014) that must be opened in the RMU firewall that would no be obviously open as per the "lmutil lmstat -c ... -a" test above?

 

Thanks, -Roberto Gomez, gomez@psc.edu. (412) 855-0020

Hello Roberto,

Are you using the Ansys license and the Ansys license manager to run LS-DYNA? If so, you need to set the following environment variables on the client machine (cluster):

export LSTC_LICENSE=ansys
export ANSYSLMD_LICENSE_FILE=1055@acadlms03.ad.rmu.edu

The default port for the Ansys license is 1055.

 

Let me know if this helps or not.

 

Reno.

Hi Reno,

I think the answer is yes, they are using the Ansys license manager, they provided me with their Entitlement ID if you need it to verify.

This is what I get (first few lines) when querying their server:

[gomez@r002 temp]$  /opt/packages/ansys/shared_files/licensing/linx64/lmutil lmstat -c 27014@acadlms03.ad.rmu.edu -a | more
lmutil - Copyright (c) 1989-2015 Flexera Software LLC. All Rights Reserved.
Flexible License Manager status on Wed 1/31/2024 13:29

License server status: 27014@ACADLMS03.ad.rmu.edu
    License file(s) on ACADLMS03.ad.rmu.edu: C:\Program Files\ANSYS Inc\Shared Files\Licensing\license_files\ansyslmd.lic:

ACADLMS03.ad.rmu.edu: license server UP (MASTER) v11.19.0

Vendor daemon status (on ACADLMS03.ad.rmu.edu):

  ansyslmd: UP v11.19.0

Setting just those two environment variables and retrying, I end up with:

[gomez@r002 temp]$ mpirun -np 1 ./ls-dyna_mpp_d_R10_2_0_x64_centos65_ifort160_avx2_intelmpi-2018 i=Main_ALE_Boundary_Controls.k memory=500m
 License option : check ansys licenses only

 Please contact your ANSYS Sales Representative or ANSYS, Inc.

I don't know if this helps, but I thought of checking if those ports are open on their firewall:

[gomez@r002 temp]$ telnet acadlms03.ad.rmu.edu 2325
Trying 192.203.233.236...
^C
[gomez@r002 temp]$ telnet acadlms03.ad.rmu.edu 1055
Trying 192.203.233.236...
^C

I think they are not open, while the port that I was told the license server is setup on (27014) is open:

[gomez@r002 temp]$ telnet acadlms03.ad.rmu.edu 27014
Trying 192.203.233.236...
Connected to acadlms03.ad.rmu.edu.
Escape character is '^]'.
^CConnection closed by foreign host.

Your help is much appreciated.

Best, -Roberto

[Reno Genest]

Hello Roberto,

Please make sure port 1055 and 2325 are open. I don't know what port 27014 is.

 

Let me know how it goes.

 

Reno.

As a new user of ansys, I may have encountered an "Unauthorized use infringes LSTC copyrights" issue. When I modified an environment variable, the issue was not resolved. I don't know what other problem is causing me to not be able to do the calculations properly. Thank you for your help.

Thank you.
