A framework for parallel visualization at Pacific Northwest National Laboratory (PNNL) is being developed that utilizes the IBM Scaleable Graphics Engine (SGE) and IBM SP parallel computers. The SGE allows disjoint regions of pixel data to be transferred simultaneously from multiple compute nodes into a unified frame buffer. The joined graphics data is displayed on monitors attached to the SGE. Three parallel applications have been developed that write pixel data directly to local buffers and transfer the buffers to the SGE. A library is being developed to allow OpenGL applications to run in parallel and utilize the SGE. The library and SGE hardware will be an interactive framework for parallel visualization applications.
