Jon “maddog” Hall during his Keynote address at the first annual Colorado Linux Info Quest, cited the University of Sao Paulo for developing a clustered Linux system to interpret mammograms within ten minutes of receipt (via FTP) from the hospital.
Maddog noted that this quick turnaround of mammogram results enabled patients needing immediate treatment to be notified before they sometimes even completed the visit paperwork. The sheer speed and power of the clustered Linux supercomputer made this feat possible, as no other technology available was able to come close (20 hours processing time was best time prior).
