NCAR's fleet of supercomputers is led by BlueGene/L. This IBM machine, a densely-packed, massively parallel computer, requires a fraction of the power and space of most production systems. Joining BlueGene/L at NCAR are a variety of other machines by IBM and other manufacturers. Together, they provide valuable support for scientists at NCAR and those at collaborating universities, who can access the computers remotely for specific projects.
