      An approach to the implementation of virtual common memory shared by multiple processors in quasi-transputer systems is presented. The approach is based on the concept of free migration of pages to the places where they are more frequently used. This optimizes automatically the data distribution between processors during Hun-time. Besides, any single processor gains access to large amount of virtual memory. Basic principles of the experimental implementation for the transputer system with linear topology are described. Relative performance considerations of traditional message-passing discipline and the approach presented are briefly examined.
