Execute tasks from another task in parallel.

[ghost]

Hi all! I have a problem with migration from fabric1 to fabric2 (as described in title).
I know I can run pre-defined command in parallel using fabric.group.ThreadingGroup, but what about tasks?
In fabric1 we could do something like this:

from fabric.api import execute, parallel

hosts = ['host1', 'host2']

def task(...):
   ""Logic here""

result = execute(parallel(task), hosts=hosts, **kwargs)

Is it possible to reimplement similar logic in fabric2?
