From a press release at Sandia.gov: A computer program that enables a collection of
off-the-shelf desktop computers to rank among the world's fastest
supercomputers has been released to the public by Sandia National
Laboratories. The program, called Cplant system software, dramatically
extends the capability of researchers to modularly assemble large blocks of
off-the-shelf computer components.
The rationale behind this open-source release is to allow researchers free
access to the body of research and development that created the most
scalable, Linux-based, off-the-shelf computer available, says Sandia
manager Neil Pundit.
