AVS is a widely used package for scientific visualization which runs on platforms ranging from workstations to Cray Research parallel vector supercomputers. AVS employs a dataflow network architecture in which modules from several extensive libraries are interconnected to perform the desired visualization functions. This paper discusses the adaptation of AVS modules to the CRAY T3D for parallel execution. The implementation issues discussed in the paper are: (1) T3D I/O and control, (2) module generation and (3) parallel computational algorithms for the modules using MPI. Examples of AVS modules from the supported library as well as user-generated models which execute on the T3D are described.
