Altair Accelerator, previously known as NetworkComputer (NC), is a commercial job scheduler developed by Altair Engineering. The product was originally developed by Runtime Design Automation (RTDA) before Altair acquired the company.

Accelerator is used to manage a computer farm or computer cluster and is responsible for accepting, scheduling, dispatching, and managing the remote execution of standalone, parallel, or interactive user jobs. It also manages the allocation of resources such as processors, memory, disk space, software licenses, and custom objects to jobs that require them.

Accelerator uses a unique event-driven scheduler that results in very low overhead per job, usually in the millisecond range.
