    My guess is; you'd need to write a virtual device driver that makes the OS think you have a normal disk attached. The virtual driver would act like a bridge between the OS and a RAID layer. This RAID layer would handle all the low level disk access. Read and write. The low level code would have to spread your files (including parity) across a minimum of 3 disks. Hope this helps. I don't have any Linux experience so I don't know how drives get mounted. So if anyone knows please correct me. :)

    well i have some sort of question regarding implementation of some algorithm in linux related to parallel processing...kindly help me out..

    well i need the
    1.code of implementing one to all broadcast and all to one reduction for a ring..
    2.implementing ALL to All broadcast and reduction for mesh
    3.Implemenation of ALl reduction for hypercube..
    kindly if any one have the stuff related to my post kindly do paste the code if u have..
