[Haskell-cafe] Distributing Haskell on a cluster

Hi all,
I have posted the following question on stackoverflow, but so far I have
not received an answer.

I have a piece of code that process files,

processFiles ::  [FilePath] -> (FilePath -> IO ()) -> IO ()

This function spawns an async process that execute an IO action. This IO
action must be submitted to a cluster through a job scheduling system (e.g

Because I must use the job scheduling system, it's not possible to use
cloudHaskell to distribute the closure. Instead the program writes a new
*Main.hs* containing the desired computations, that is copy to the cluster
node together with all the modules that main depends on and then it is
executed remotely with "runhaskell Main.hs [opts]". Then the async process
should ask periodically to the job scheduling system (using *threadDelay*)
if the job is done.

Is there a way to avoid creating a new Main? Can I serialize the IO action
and execute it somehow in the node?
