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 Slurm).

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?

Best,

Felipe
