# 1.5. What Is Not Included In The Standard?

Up: Introduction to MPI Next: Organization of this Document Previous: What Is Included In The Standard?

The standard does not specify:

- Explicit shared-memory operations
- Operations that require more operating system support than is currently standard; for example, interrupt-driven receives, remote execution, or active messages
- Program construction tools
- Debugging facilities
- Explicit support for threads
- Support for task management
- I/O functions

There are many features that have been considered and not included in this standard. This happened for a number of reasons, one of which is the time constraint that was self-imposed in finishing the standard. Features that are not included can always be offered as extensions by specific implementations. Perhaps future versions of MPI will address some of these issues.
