Load Balancer is a UNIX batch queueing and load sharing system. It ensures that jobs (ie: applications) submitted from any host in a network end up running on the best available host. It takes into account many performance factors and other real-world factors. Users can run, kill, and adjust the status of their jobs from any host, and can also get status information on jobs, queues, hosts, applications, and users from any host. No application or kernel modifications are necessary, since Load Balancer deals exclusively with whole applications, not application fragments.
The user does not have to specify which host the job should run on. Load Balancer makes this choice at run-time based on such factors as load average, ram/swap requirements, application-specific host speed differences, presence/absence of interactive users on a host, licensing information, host availability schedules, queue depths, user-specific host and application access permissions, queueing priorities, and so on.
Load Balancer is available on SGI, Sun, IBM, DEC, and HP UNIX computers.
