Abstract
BlueGene/L (BG/L), developed through a partnership between IBM and Lawrence Livermore
National Laboratory (LLNL), is currently the world's largest system both in terms of
scale with 131,072 processors and absolute performance with a peak rate of 367 TFlop/s.
BG/L has led the Top500 list the last four times with a Linpack rate of 280.6 TFlop/s for
the full machine installed at LLNL and is expected to remain the fastest computer in the
next few editions. This talk will detail how we overcame the challenges of scaling the
system architecture and software, as well as novel innovations for supporting tools at
this scale. More importantly, it will present performance and scientific results from real
applications that demonstrate the real value of a machine like BG/L.
