UNIX is the OS of choice for parallel computing, because you don't want your large application (which runs 2 weeks or more) be interrupted by messages like "Windows Error: User has modified a file. Please reboot to make changes permanent!" or "Memory Fault: User has referenced memory outside of my 64KByte address space!" ;-)) For Clusters of PCs, Linux is the top candidate. > Which components must we install on an UNIX OS to manage a parallel > computer OR is it the same UNIX OS ? Depends on your application: For message passing, MPI and its implementations (MPICH, LAM) are the way to go. For shared memory, PThreads are a standard tool. Have a look at a book about Parallel Computing. You should find enough references, where you can get more info.
