The Teramac was an experimental massively parallel computer designed by HP in the 1990s.
The name reflected the project's vision to provide a programmable gate array system with capacity for a million gates running at a megahertz.
Even though the computer had 220,000 hardware defects, it was able to perform some tasks 100 times faster than a single-processor high-end workstation.
Although it contained conventional silicon integrated circuit technology, it paved the way for some of HP's work in nanoelectronics because it provided an architecture on which a chemically assembled computer could operate.
The experience from this program was used to design the Field Programmable Nanowire Interconnect circuit.
