      Abstract
      This paper describes the background and development of PICSIL1 a visual language for specifying parallel algorithms using structured decomposition. PICSIL1 draws upon graphical and textual specification techniques; the first for high level structure of an algorithm, the second for more detailed functional specifications. The graphical specification techniques used in PICSIL1 are based on Data Flow Diagrams (DFDs) and are well suited to the assembly and interconnection of abstract modules. Minor modifications to DFDs have however had to be made to make them suitable for describing parallel algorithms. These include the ability to dynamically replicate sections of a diagram and change the structure of parts of a diagram dependent on data being processed. Work is proceeding on the development of an editor to allow the direct capture and editing of PICSIL1 descriptions. In the near future development of compiler and visual debugging tools are planned.
