    7777
    78 A thread of parent process P, running in a cluster X,  executes the fork() system call to create a child process C on a remote cluster Y, that will  become both the owner and the reference cluster for the C process. A new process descriptor, and a new thread descriptor must be created and initialized in target cluster Y for the child process.
     78The fork() system call is the only method to create a new process. A thread of parent process P, running in a cluster X,  executes the fork() system call to create a child process C on a remote cluster Y, that will  become both the owner and the reference cluster for the C process. A new process descriptor, and a new thread descriptor must be created and initialized in target cluster Y for the child process.
    7979The calling thread  can run in any cluster. If the target cluster Y is different from the calling thread cluster X, the calling thread must use a RPC to ask the target cluster Y to do the work, because only the target cluster Y can allocate memory for the new process and thread descriptor.
