  LS-OPT is a standalone Design Optimization and Probabilistic Analysis package with an interface to LS-DYNA. - Homepage:

  Sets up environment for LS-OPT 5.2. A module for LS-DYNA will also be loaded for use with this module.  Use the lsopt command to start LS-OPT or the lsoptui command to start the LS-OPT GUI.  The manual is located at /software/tamusc/LS-OPT/5.2/LSOPT_EXE/lsopt_52_manual.pdf 

Usage on the Login Nodes

Please limit interactive processing to short, non-intensive usage. Use non-interactive batch jobs for resource-intensive and/or multiple-core processing. Users are requested to be responsible and courteous to other users when using software on the login nodes.

The most important processing limits here are:
* ONE HOUR of PROCESSING TIME per login session.

  • EIGHT CORES per login session on the same node or (cumulatively) across all login nodes.

Anyone found violating the processing limits will have their processes killed without warning. Repeated violation of these limits will result in account suspension.
Note: Your login session will disconnect after one hour of inactivity.

Usage on the VNC Nodes

The VNC nodes allow for usage of the a graphical user interface (GUI) without disrupting other users.

VNC jobs and GUI usage do come with restrictions. All VNC jobs are limited to a single node (Terra: 28 cores/64GB). There are fewer VNC nodes than comparable compute nodes.

For more information, including instructions, on using software on the VNC nodes, please visit our Terra Remote Visualization page.

NOTE: LS-OPT should be started with vglrun when used via VNC jobs .
