Hi , I have a multiple processes which are modifying hash of hash of array. For multiprocessing I am using Parallel::ForkManager
The requirement is I set Max processes to say 5. Each process is fired by the script and max 5 parallel process runs and it performs some actions on a complex datastructure like each process after performing a task based on success moves user entry from pending hash key to completed hash key. Now this task needs to be run on around 10K users and I need not run this more than 1 hr after which I need to store the state disc which I can revisit and start from point where I left. I am planning to use Storable module for storing and retrieve later. My question is do I need to implement locks on write operation as multiple Procs will be writing data to same complex datastructure ? or just using store() in each process will take care of simultaneous writes ? Any pointers to some code will be helpful. Thanks and Regards, Puneet
