Description

This module enables parallelism in Dinfio. You can run multiple processes simultaneously. This is useful for intensive operations, like Networking, File IO, Computation, etc.

Constants

• process_arguments — This constant stores arguments that can be consumed by a child process

Functions

• clear_done_callback() — Clear callback when all processes are finished running
• pack() — Pack any value into a string. This is useful when you want to pass array or simple object to the parent/child process. This function is a wrapper of json.encode({packed: ...}). Warning: this function is now deprecated, and will be removed on the future release
• process() — Run .fio file in a separate process (child process)
• process_return() — Return a value to parent process and terminate the child process
• process_yield() — Yield a value to parent process
• set_done_callback() — Set callback when all processes are finished running
• total_cpu() — Get the number of logical CPUs in the system
• unpack() — Unpack a packed string from the parent/child process. This function is a wrapper of json.decode(...). Warning: this function is now deprecated, and will be removed on the future release
• void() — A void function. Use this function if you don't want to add callback to your process. Warning: this function is now deprecated, and will be removed on the future release. Please use nothing instead if you don't want to add callback to your process

Examples

import multiprocess
 
start
    process("child_1")
    process("child_2", [23], on_updated(), on_returned(), on_finished())
stop
 
function on_updated(data)
    writeln("Updated data from child #2: " & data)
stop
 
function on_returned(data)
    writeln("Returned data from child #2: " & data)
stop
 
function on_finished()
    writeln("Child #2 finished")
stop

' Child #1 - child_1.fio
 
import multiprocess
 
start
    writeln("Child #1 started")
    sleep(2000)
    writeln("Child #1 finished")
stop

' Child #2 - child_2.fio
 
import multiprocess
 
start
    n = process_arguments[0]
 
    process_yield(n * 2)
    process_return(n ^ 2)
stop

' Example output:
'
' Child #1 started
' Updated data from child #2: 46
' Returned data from child #2: 529
' Child #2 finished
' Child #1 finished
