The AVS/Express Distributed Data Renderer visualization product has been ported to HECToR to allow visualization of large datasets using parallel software rendering. A number of changes to the AVS code were required to run in the HECToR environment, the most significant being the ability to make MPI calls from the main AVS/Express user interface executable running on a login node, and the addition of an MPI-based image compositing scheme. Initially the MRBV project was only considering non-interactive batch execution of AVS/Express. However scalability improvements in the code allow interactive use with higher process counts than any other previous installation of the product.
