# icetDestroyMPICommunicator(3)

## NAME

**icetDestroyMPICommunicator -- deletes a MPI communicator**

## Synopsis

\#include \<IceTMPI.h\>

| | | |
| --- | --- | --- |
| void **icetDestroyMPICommunicator**( | **IceTCommunicator** | *comm* ); |

## Description

Destroys an **IceTCommunicator**. *comm* becomes invalid and any memory or MPI resources held by *comm* are freed.

Communicators are copied when attached to an **IceT** context, so destroying an **IceTCommunicator** used to create a context still in use is safe.

## Errors

None.

## Warnings

None.

## Bugs

All MPI errors are ignored.
