I'm doing research on system support for reliable parallel processing, and I would like to get my hands on source code for some open-source real-world applications or research programs that use ScaLAPACK. I'm looking for something that is not as simple as ScaLAPACK's example programs. For example, I've found that Socorro (http://dft.sandia.gov/Socorro/mainpage.html) uses ScaLAPACK.
Any pointers would be appreciated. Thank you.
