It ensures that the workload is properly distributed across processors such that there no resources are idle if an application can use it and it can constrain the access to resources to ensure the application is well behaved when contending for resource. It can easily be combined with the ASPEED Application Manager to provide even more fine grained application specific resource utilization dynamics.

The Workload Balancer dispatching daemon uses a dynamic allocation algorithm to allocate runs to CPUs so as to minimize the overall time of execution. It is designed for organizations that want to maximize the utilization of their multi-system configurations e.g., workgroup or cluster if no grid fabric is present.

The ASPEED Workload Balancer software includes:

• A dispatch daemon which reads in the list of computers and their number of CPUs, and allocates (“dispatches”) jobs/applications and its steps. This daemon runs on one machine in the workgroup/cluster. It accepts submissions, spawns (runs) jobs, schedules jobs and accepts/processes commands.

• An application/job submitting executable can submit or “dispatch” any number of jobs with options like estimated time of execution and maximum number of CPUs the user wants the for the ASPEED accelerated  job.

• A remote command line interface to the daemon which enables the administrator to issue commands and see the status.

The SIMtone ASPEED Workload Balancer with the ASPEED Application Manager and ASPEED accelerated application is an excellent entry vehicle for efficiently sharing a cluster prior to  grid infrastructure roll-out or to demonstrate the significant performance improvements that can be achieved while actually benefiting from it.

The SIMtone ASPEED Workload Balancer supports Windows and Linux environments and includes an interface to the Tivoli Workload Scheduler.
