 The process creation in a remote cluster implements the POSIX fork() / exec()  mechanism.
 When a parent process P executes the fork() system call, a new child process C is created.
-The new C process inherits (from the parent process P) the open files (FDT), and the memory image (VSL and GPT). These structures must be replicated in the new process descriptor. After a fork(), the C process can execute an exec() system call, that allocates a new memory image to the C process, but the new process can also continue to execute with the inherited memory image. For load balancing, ALMOS-MKH uses the DQDT to create the child process C on a different cluster from the parent cluster P, but the user application can also use the non-standard fork_place() system call to specify the target cluster.
