NAME

Parallel::WorkUnit::Procedural - Provide procedural paradigm forking with ability to pass back data

VERSION

version 2.202230

SYNOPSIS

#
# Procedural Interface
#
use Parallel::WorkUnit::Procedural qw(:all); # Export all symbols

async sub { ... }, \&callback;
waitall;


#
# Limiting Maximum Parallelization
#
WorkUnit->max_children(5);
queue sub { ... }, \&callback;
waitall;


#
# Ordered Responses
#
async sub { ... };

@results = waitall;

#
# Spawning off X number of workers
# (Ordered Response paradigm shown with 10 children)
#
asyncs( 10, sub { ... } );

@results = waitall;


#
# AnyEvent Interface
#
use AnyEvent;

WorkUnit->use_anyevent(1);
async sub { ... }, \&callback;
waitall;  # Not strictly necessary

#
# Just spawn something into another process, don't capture return
# values, don't allow waiting on process, etc.
#
start { ... };

DESCRIPTION

This provides a simple procedural instance to Parallel::WorkUnit where it is not important to modify attributes of the global Parallel::WorkUnit singleton used by this module.

While the underlying singleton is exposed (via the WorkUnit subroutine), it is highly recommended that users not use this directly, as unexpected interactions may occur (it is a global singleton, after all!).

Please read the documentation on Parallel::WorkUnit for detailed information about this module.

This module was added to the Parallel-WorkUnit distribution in 1.191810.

FUNCTIONS

WorkUnit

Returns the singleton Parallel::WorkUnit used by this module. This can be used to access attributes such as max_children and use_anyevent.

async { ... }, \&callback

async sub { return 1 } \&callback;

# To get back results in "ordered" return mode
async sub { return 1 };
@results = waitall;

This executes Parallel::WorkUnit-async()>

asyncs( $children, sub { ... }, \&callback )

Executes Parallel::WorkUnit-asyncs() }

waitall

Executes Parallel::WorkUnit-waitall()>

waitone

Executes Parallel::WorkUnit-waitone()>

proc_wait($pid)

Executes Parallel::WorkUnit-wait()>

proc_count()

Executes Parallel::WorkUnit-count()>

queue sub { ... }, \&callback

Executes Parallel::WorkUnit-queue()>

start { ... };

This executes Parallel::WorkUnit-start()>
