Method and system for providing discrete user cells in a UNIX-based environment

A method of providing multiple, discrete, secure work areas in a computer system having a disc storage facility, a CPU, a memory module and a set of IP addresses, comprising:

• designating plural autonomous resource units(ARUs) in the disc storage facility;
• providing a barrier to prevent inter-ARU communications;
• assigning a discrete identifier to each ARU;
• and
• connecting each ARU to a CPU and memory module associated with the disc storage facility.

A system of multiple work areas for operating within a computer system, wherein the computer system includes a CPU and a memory module, comprising:

• plural autonomous resource units(ARUs), for running user processes, wherein each ARU includes a discrete IP address, and wherein a process running in one ARU is inaccessible by another ARU;
• a discrete identifier assigned to each ARU;
• a process look-up table containing said discrete identifier therein;
• a perhost look-up table for restricting access by a process to said IP address;
• a disc storage facility including a common storage region, wherein parent processes are contained in said common storage region, and wherein a parent process spawns a child process which is tagged with said discrete identifier and loaded into an ARU;
• and
• a connector which extends to between each ARU and the computer system CPU and memory module.
