This paper presents conception of virtual shared files (VSF) as paradigm of parallel components interaction.metaphor of virtual shared files space ensures a compromise between flexibility of explicit message passing and transparency of shared memory model.VSF are based on ordinary I/O notion and look like matrixes and ordinary files fro application programmers.The most essental design issues are: all operations are applied to a file as a whole;operations remotely chanign the content of file are prohibited; memory is explicitly allocated by user what is essential for massively-parallel computers.
