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.
