HPC Visualization

This project was created for CICA's Fall '96 Open House to illustrate the effect of distributing a large computation over multiple processors using a different techniques (PVM, HPF) and numbers of processors.

Categories: Visualization, High-Performance Computing
Participants: * Don Berry, CICA - HPC programming
* Eric Wernert, CICA - visualization
Dates: October 1996
Resources: * Iris Explorer visualization environment on SGI workstations,
* custom Explorer modules for reading and synchronizing simulation trace files

Productions

The images below show four different runs of a heat diffusion simulation running on 1, 2, 4, and 8 processors. At a given elapsed time (150 seconds in this case), the progress of the computations can be visualized and compared. (The lower the "bump", the further the computation has progressed.) This simulation was coded in High-Performance Fortran and was run on IU's SP2 supercomputer.
