# Interface ICompute

Defines Ignite functionality for executing tasks and closures over nodes in the IClusterGroup. Instance of ICompute is obtained from grid projection using GetCompute() method.

Note that if attempt is made to execute a computation over an empty projection (i.e. projection that does not have any alive nodes), `ClusterGroupEmptyException` will be thrown out of result task.

Ignite must select a node for a computation to be executed. The node will be selected based on the underlying `GridLoadBalancingSpi`, which by default sequentially picks next available node from grid projection. Other load balancing policies, such as `random` or `adaptive`, can be configured as well by selecting different load balancing SPI in Ignite configuration. If your logic requires some custom load balancing behavior, consider implementing `ComputeTask` in Java directly.

Ignite guarantees that as long as there is at least one Ignite node standing, every job will be executed. Jobs will automatically failover to another node if a remote node crashed or has rejected execution due to lack of resources. By default, in case of failover, next load balanced node will be picked for job execution. Also jobs will never be re-routed to the nodes they have failed on. This behavior can be changed by configuring any of the existing or a custom `FailoverSpi` in Ignite configuration.

All members are thread-safe and may be used concurrently from multiple threads.
