4. `parsl.executors.taskvine.TaskVineExecutor`: This executor uses `TaskVine `_ as the execution backend. TaskVine scales up to tens of thousands of cores and actively uses local storage on compute nodes to offer a diverse array of performance-oriented features, including: smart caching and sharing common large files between tasks and compute nodes, reliable execution of tasks, dynamic resource sizing, automatic Python environment detection and sharing.
These executors cover a broad range of execution requirements. As with other Parsl components, there is a standard interface (ParslExecutor) that can be implemented to add support for other executors.
+5. `parsl.executors.globus_compute.GlobusComputeExecutor`: This executor uses `Globus Compute `_
+as the execution backend to run functions on remote systems.

.. note::
Refer to :ref:`configuration-section` for information on how to configure these executors.

+ As a remote execution system, Globus Compute relies on serialization to ship
