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.
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.
Subordinate Resources
The subordinate resources are the resources of a job that appear after the first '--' in the resource specification.

- 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.
  - Connect to a Third Party Batch Processing System
    FlowTracer provides default implementations of interfaces for some of the Batch Processing Systems. FlowTracer also provides Tcl APIs for easy, flexible and extensible implementation of interfaces to the Batch Processing System of your interest. This enables FlowTracer to fit into any existing Enterprise Grid.
  - Interface FlowTracer with Accelerator
    There are two ways to interface FlowTracer to Accelerator.
  - Interfaces to Other Batch Processing Systems
    You can find examples of interfaces in the directory $VOVDIR/etc/tasker_scripts. The file $VOVDIR/etc/tasker_scripts/taskerLSF.tcl implements the interface to LSF.
  - Subordinate Resources
    The subordinate resources are the resources of a job that appear after the first '--' in the resource specification.
  - Interface with LSF using taskerLSF.tcl
- 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.
- Advanced Information
- 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.

Subordinate Resources

The subordinate resources are the resources of a job that appear after the first '--' in the resource specification.

For example, in the resource specification:

JobType:compile -- ( alpaca OR sun7 )

The subordinate resources is the string (alpaca OR sun)

These subordinate resources are used by indirect taskers in the submission of the job to the remote BPS.

In the following example, the primary resource is NC, which is a simple way to route a job towards an indirect tasker connected to Accelerator, while License:drc1 OR License:drc2 is the subordinate resource which will be used when the job is transferred to Accelerator.

R "NC -- License:drc1 OR License:drc2"
J vw run_some_drc Chip.x

The field to access the subordinate resources is called "SUBRESOURCES".
