Altair FlowTracer Administrator Guide
This manual is aimed at the person who will be the administrator for FlowTracer. This person will be responsible for configuring the network resources, setting up the licensing, and establishing security and access rules for the system.
Multi-User Altair FlowTracer
FlowTracer now supports a "multi-user" mode of operation, as a Beta feature. In the multi-user mode, many different users can share the same project, in terms of modifying a flow as well as running different compoments of the flow.

- FlowTracer Roles
  When using FlowTracer in large deployments, three main roles emerge: Administrator, Developer and User. In smaller organizations, a given person may have multiple roles, but the duties of each role still exist.
- Enable CLI Access on UNIX
  This section explains how to set up a UNIX user's shell environment to have a proper context for the user to run installed Altair Accelerator programs from the command line. The programs that are run from the command line are called the CLI commands.
- Enable CLI Access on Windows
  This section explains how to set up a Window user's command prompt environment to have the proper context for the user to run installed Altair Accelerator programs from the command line. The programs that are run from the command line are called the CLI commands.
- User Interfaces
- Use FlowTracer Help
  FlowTracer documentation is available in HTML and PDF format.
- Projects
- Server Working Directory
  When a project is created, a server working directory (.swd directory) is created to hold configuration and state information about the project.
- Alerts
  VOV issues an "alert" when an event requires attention. An alert can range from information that does not require action to an urgent fault that requires immediate action.
- Manage the Server for a Project
- Security
  The VOV security model consists of assigning a Security Code to each client or client group (VovUser Group) and granting the permission to execute critical tasks only to clients with the appropriate security level.
- Taskers
  A tasker is a VOV client that provides computing resources, specifically CPU cycles, to the vovserver.
- Interfaces to Accelerator, SGE, LSF, and Others
  FlowTracer can be used also as a front end to an existing batch processing system (BPS), for example, Accelerator, LSF, SGE, SGEEE, etc.
- Configuration for Elastic Computing
- Configuration for Altair Accelerator
- Configure a Failover Server Replacement
  If a server crashes suddenly, VOV has the capability to start a replacement server on a pre-selected host. This capability requires that the pre-selected host is configured as a failover server.

Multi-User Mode Setup: Project Owner

All users who are expected to share the FlowTracer project must belong to a common UNIX group.

Note: The IT department should create a UNIX group, if one doesn't already exist, that includes all the users who need to work on this shared project. (For these instructions, let's use a group called "designers".)

The steps that follow should be completed by the project owner.

The project owner will create a new project, ensuring that he/she is using the designers UNIX group as the default group. This can be ensured by running the UNIX command newgrp:
```
% newgrp designers
% source <installation_directory>/<version>/<platform>/etc/vovrc.csh
% vovproject create <projectname>
% vovproject enable <projectname>
```
Create a vovusergroup called "designers" from the UNIX group "designers".
This will add all the users of the UNIX group "designers" as members of the vovusergroup "designers".
```
% vovusergroup populate designers -unix designers
```
Assign the LEADER role to the vovusergroup designers. For this, modify the security.tcl file to include the following line:
```
vtk_security -group designers LEADER +
```
Set the environment variable VOV_FT_MULTIUSER to tell vovlsfd that FlowTracer is running in multi-user mode.
In this mode, vovlsfd will only accept and submit jobs for the user who started this instance of vovlsfd.
Restart the project so all the new settings will take effect.
Start vovlsfd to enable taskers to submit jobs to LSF.
The project is now ready for use by other members of the designers group.
