Distributed homogeneous operating systems

Abstract

In his opening presentation. Gerald Kreissig (IBM Bobhngen Labora tory , W. Germany) described various degrees of ne twork t ransparency that are, in his opimon, required to achieve a homogeneous d~stributed system. He dtstingutshed between access fr,~r~.L~rerLQV, where a process has the same type of access mechanism for both ic~al and remote resources; L_-.cas~on trar, sF~renc~, where the location of a resource is ln~-isible to the access method: corarol tr._xr~ly~renQv, where all informatmn descr'_,bing a system has identical appearance to a user or application, and exe~.aion transpa~en-~, which allows load balancing, moving programs to the data, inter-process communica tmn between processes on different prc~zessors, etc. Each one is a superset of its predecessors" functions.
