Abstract:
A fork system call by a first process is detected. A second process is created as a replication of the first process with a second affinity. If a replication of the replicated shared library is present in the second affinity domain, effective addresses of the replication of the replicated shared library are mapped using a mapping mechanism of the present invention to physical addresses in the second affinity domain.
