Conduction-Cooled 800 MHz 6U VME Multicomputer delivers 460 GFLOPS
Mercury Computer Systems, Inc. has announced the availability of its Conduction-Cooled 800 MHz 7447A 6U VME Multicomputer, which the company claims is the most powerful commercial off-the-shelf (COTS) multiprocessing system available today for deployment in extreme environments.
The Conduction-Cooled Multicomputer can scale up to 72 PowerPC 7447A compute nodes connected by the high-bandwidth Mercury RACE++ Series communications fabric, for a total of 460 GFLOPS in processing power. It is designed to meet the company's Level 3 environmental specifications, which are intended for harsh operating environments that include extreme heat or cold, humidity, shock and vibration, little or no airflow, and dirty or corrosive atmospheres.
Each conduction-cooled module consists of an MCJ6 motherboard with either one or two daughtercards. A processing daughtercard supports two compute nodes (CNs), each consisting of a PowerPC 7447A microprocessor with AltiVec technology, fast on-chip Level 2 (L2) cache, double data-rate (DDR) SDRAM, and a Mercury-designed CN interface chip. The 800 MHz CN daughtercards use high coefficient of thermal expansion (HCTE) PowerPCs, which greatly increase the tolerance to thermal expansion and contraction stress as a result of temperature cycling.
High-speed front panel data port (FPDP) I/O daughtercards may also be configured onto an MCJ6 motherboard with a processing daughtercard. Board-to-board communication takes place through RACE++ Series Interlink modules. These components form the backbone of a RACE++ switch fabric, supporting multiple high-speed data transfers simultaneously through multiple pathways.
The Conduction-Cooled 800 MHz 7447A Multicomputer is currently available for customer shipments with standard lead times.
