NLTSS is a group of server processes and a message system kernel which can reside on a CRAY-1 computer and provide the functionality of a local operating system, plus the capability for distributed computing. NLTSS can incorporate access to new network resources more easily than can LTSS. The external aspects of the NLTSS system will initially be constrained to resemble those of LTSS. NLTSS interactive terminal commands will be the same as LTSS commands, when possible, similar if sameness isn't possible, and in some instances omitted. The latter category is comprised of LTSS-specific inquiries. Libraries are being designed and implemented by USD to provide a BASELIB-like interface to the system. Generally, the system primitives need not be well understood by the application-level user. There are some differences; e.g., a process and a file are different kinds of objects. The method for accessing each is generally the same, however. This difference should be largely hidden from the high-level user. Another example, the dollar accounting control (the alpha codes; e.g., ACD) is more rigorously managed, and resource usage more completely reported.
