Re: [Fab-user] Usage of parallel option in fabric

[Morgan Goose]

use execute for switching on the fly if the fab -P/--parallel flag
doesn't work for you:

def foo():
    pass

@task
def bar():
    execute(parallel(foo), hosts=host_list)
    execute(foo, hosts=other_host_list)


On the second question, what are you actually asking? Also we use
multiprocessing not gevent, to get parallel execution, over
concurrency.
