2025.1.0
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.
View new features for FlowTracer 2025.1.0.
An advanced mission critical dependency management platform for developing and executing flows.
Discover FlowTracer functionality with interactive tutorials.
FlowTracer is a complete system to create, manage, and execute design flows.
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.
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.
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.
FlowTracer documentation is available in HTML and PDF format.
When a project is created, a server working directory (.swd directory) is created to hold configuration and state information about the project.
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.
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.
A tasker is a VOV client that provides computing resources, specifically CPU cycles, to the vovserver.
FlowTracer can be used also as a front end to an existing batch processing system (BPS), for example, Accelerator, LSF, SGE, SGEEE, etc.
vovwxd is a daemon used for dynamically requesting taskers from another job scheduler, that is, a base queue. This process is referred to as elastic computing. This daemon is the key component of the Accelerator Plus product and is also used with FlowTracer when interfacing with an external job scheduler.
You can configure FlowTracer to allocate jobs on CPUs managed by LSF while avoiding the taxing per-job scheduling overhead imposed by LSF. You do this by adding the daemon program vovlsfd to the set of service programs that run in the background.
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.
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.
