Parallel Lua Virtual Machine

Synopsis

(p)lvm is the world only parallel multi-instance virtual machine supporting the original Communicating Sequential Processes model following the Hoare semantics supporting additional concurrency! (p)lvm supports multi-processing, multi-threading, and fibers. And the fully self-contained program lvm is about 1MB size only! Available for multiple operating systems.

Process Constructors

• Seq
• Par
• Fork
• Co
• Alt

Interprocess Communication Objects

• Mutex
• Semaphore
• Chanell
• Barrier
• Event
• Timer

The advantage of the Lua VM under the hood is the full support of process blocking and process switching in threads and fibers (co-routines).

Programming

To use the parallel processing features open the Csp module:

require 'Csp'
log('Creating Par..')
Par({
  function ()
    sync:await()
    log('1: Thinking')
    fork1:down()
    fork2:down()
    log('1: Eating')
    sleep(500)
    fork1:up()
    fork2:up()    
  end,
  function ()
    sync:await()
    log('2: Thinking')
    fork2:down()
    fork1:down()
    log('2: Eating')
    sleep(500)
    fork2:up()
    fork1:up()    
  end,
  function ()
    sync:await()
    log('3: Thinking')
    fork2:down()
    fork1:down()
    log('3: Eating')
    sleep(500)
    fork2:up()
    fork1:up()    
  end
},{
  sync=Barrier(3),
  fork1=Semaphore(1),
  fork2=Semaphore(1)
})
log('After Par ..')
