A researcher at Robert Morris University is trying to run <\/div>\n
LS-DYNA (ls-dyna_mpp_d_R12_1_0_x64_centos78_ifort160_avx2_intelmpi-2018) on our RHEL 8.8 cluster (bridges2.psc.edu<\/a>) 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<\/a>.  <\/div>\n
 <\/div>\n
We verified we can contact the license server from the Bridges2.psc.edu cluster  at PSC and can query it, e.g.:<\/div>\n
 <\/div>\n
$ \/opt\/packages\/ansys\/shared_files\/licensing\/linx64\/lmutil lmstat -c 27014@acadlms03.ad.rmu.edu<\/a> -a<\/p>\n<\/div>\n
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.<\/div>\n
 <\/div>\n
But, we are not getting LS-DYNA to talk to the license server. We tried setting (bash shell):<\/div>\n
   <\/div>\n
   export LSTC_LICENSE=network
   export LSTC_LICENSE_SERVER=27014@acadlms03.ad.rmu.edu<\/a><\/div>\n
 <\/div>\n
and running LS-DYna with:<\/div>\n
 
$  mpirun -np <\/span>1 .\/ls-dyna_mpp_d_R10_2_0_x64_centos65_ifort160_avx2_intelmpi-2018 i=Main_ALE_Boundary_Controls.k memory=500m<\/span><\/div>\n
 <\/div>\n
but we get the error message:<\/div>\n
 <\/div>\n
 License option : check network license only<\/div>\n
      Date: 01\/29\/2024      Time: 12:16:58  <\/div>\n
 *** License problem ***
 Network license:<\/div>\n
 *** Error License client cannot find any servers to talk to.<\/div>\n
               Servers may be down, not ready, or the wrong version.<\/div>\n
 <\/div>\n
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?<\/div>\n
 <\/div>\n
