Cray, Inc., a subsidiary of Hewlett Packard Enterprise, is a manufacturer of supercomputers headquartered in Seattle, Washington.
Cray focuses on high performance computing solutions and products deployed throughout a variety of industries.
PHYTEC provided the L0 Controller Module that is used as a service processor in the Cray XT3, a third generation massively parallel processor (MPP) supercomputer. Building on the success of its predecessors, the Cray T3D™ and the Cray T3E™ systems, the Cray XT3 system brought astounding new levels of scalability and sustained application performance to high performance computing (HPC). Purpose-built to meet the special needs of capability class HPC applications, each feature and function was designed for larger problems, faster solutions, and a greater return on investment.
A custom subassembly derived from the phyCORE-SC520, the L0 initializes and boots the MPP system, generates routing tables, and monitors the health of the components on its host server blade. The L0 runs embedded Linux and interfaces through the GP bus to an FPGA on the host circuitry, which has additional devices to extend the functionality of the L0. In addition to this cabinet-level safety and control implementation, another Cray application uses the PCI bus and two additional network interfaces to turn the L0 into a network router.
