Abstract

A method for creating a process in a multicomputer system that includes interconnected multiple sites. Each site includes a local processor, local memory, and a local operating system including a local process manager server that is addressable through an associated process port identifier. The operating system includes a messaging facility for controlling the transfer of messages between different processes on different sites. A process directory structure is distributed across multiple sites. The fragmented process directory structure includes a multiplicity of slots for referencing a multiplicity of process port identifiers. A process directory port group structure is provided in the site memory of at least one of the sites, and references respective port identifiers associated with respective process managers on respective sites. A process directory port group manager is provided that is operative on at least one of the sites. A call is issued to a respective process manager server to request the creation of a new process operation. A first message is transferred from the respective process manager receiving the call to the process directory port group manager to request allocation of a slot. A second message is transferred from the process directory port group manager to a process manager associated with one of the port identifiers. The second message is a request to allocate a slot in the process directory fragment of the process manager receiving the second message. The new process creation operation is completed on the site that contains the process manager receiving the call.
