	       An Overview of Blue Gene/L Supercomputer
	     
 
			       
In this talk we present an overview of the hardware and software
architecture of the Blue Gene/L Supercomputer, a jointly funded
research partnership between IBM and the Lawrence Livermore National
Laboratory. This massively parallel system of 65,536 nodes is based on
new architecture that exploits system-on-a-chip technology to
deliver target peak processing power of 360 teraFLOPS (trillion
floating-point operations per second). The target value of 360
teraFLOPS peak is appropriate for applications that can utilize both
embedded PowerPC processors on a node. For applications that require
significant messaging protocol overhead, one of these processors may
be dedicated to messaging and is not available for computations. For
this later class of applications, the target peak performance is 180
teraFLOPS. The machine is scheduled to be operational in the 2004-2005
time frame, at price/performance and power consumption/performance
targets unobtainable with conventional architectures.
