Isotach systems are distributed or parallel computer systems with special support for interprocess coordination. Isotach systems provide low cost ordered message delivery, a basic service useful or essential in applications in which processes must share data or otherwise coordinate their actions. These applications include distributed databases, cache coherence in multiprocessors, distributed shared memory, parallel production systems, and distributed control systems. Isotach systems also provide support for fault-detection and checkpointing.

Isotach systems provide these benefits by maintaining a logical time system that enables processes to predict and control the logical time at which its messages are received. This control is a powerful mechanism for interprocess coordination in a parallel or distributed computation.
