Description
Summary:Summary form only given. In 1984, the Unisys Corporation was awarded a government contract to design and develop a multilevel secure communications system. This system contains multilevel administrative hosts that manage the connectivity between users on a network. The connectivity was driven by mandatory and discretionary policies. An early decision was made to use GEMSOS (Gemini Standard Operating Systems) as the kernal for the operating system that would reside on these administrative hosts. The decision was made to use the same compiler for the operating system and applications that Gemini used in developing GEMSOS. Experience with the GEMSOS product has been positive. GEMSOS provided adequate features to allow it to be the basis of the required operating system. The performance in the area of task creation greatly improved from the initial versions.< >
