The Connection Machines CM-1 and CM-2



CM-1

 

 

MoMA acquires CM-2 for its permanent collection

In 2016 the Museum of Modern Art in New York acquired a CM-2 for its design collection.
Just in time for its 30th anniversary, the CM-2 will be on exhibit as part of the show:

MoMA NY, November 13, 2017 - April 8, 2018

 

How the Connection Machine Design inspired Steve Jobs

Joanna Hoffman was marketing manager on the first Macintosh, and Jobs' right hand at his
company NeXT Inc. (see Kate Winslet's excellent portrayal of her in the Danny Boyle
film "Steve Jobs.") In this interview Joanna talks about how Jobs asked her to get the
designer of the Connection Machine to create his NeXT computer .

 

30th anniversaries of the Connection Machines CM-1/CM-2:

CM-1 (1986-2016) - CM-2 (1987-2017) - Gordon Bell Prize for CM-2 (1989-2019)

The Connection Machine was the first commercial computer designed expressly for problems of Artificial Intelligence (AI). A massively parallel supercomputer with 65,536 processors, it was the brainchild of Danny Hillis, conceived in the early 1980s while he was a doctoral student with Marvin Minsky at the MIT Artificial Intelligence Lab, and built by his start-up Thinking Machines Corporation.

To celebrate the tri-decennial anniversaries of these machines I have started a project to investigate their legacy over the past 30 years. In the last five years, AI has suddenly become the buzzword for radical changes in our world, from self-driving cars to the end of both blue-collar and white-collar work as we know it. In the process I have uncovered overlooked backlinks to the concepts and developments that came out of Thinking Machines in the 1980s-1990s.

Exploratory interviews with my former TMC colleagues on the legacy of their work today:
The CM as the world's first full text English search engine, how work on the CM influenced
Google as an AI company, and how the Internet and Cloud Computing today realize
the "unrealistic" dreams that began at Thinking Machines over 30 years ago.

 

1986: First commercial supercomputer modelled after the human brain

Departing from conventional computer architecture of the time, it was modeled on the structure of a human brain: rather than relying on a single powerful processor to perform calculations one after another, the data was distributed over the tens of thousands of simple 1-bit processors, all of which could perform calculations simultaneously, a configuration known as "SIMD" - Single Instruction Multiple Data.

What enabled the processors to communicate faster than previous SIMD designs was the internal network, a 12-dimensional boolean n-cube structure suggested by Nobel Prize physicist Richard Feynman, who spent his summers with us. Within this hardwired physical structure, the software data structures for communication and transfer of data between processors could change as needed depending on the nature of the problem. This meant the mutability of the connections between processors were more important than the processors themselves, hence the name "Connection Machine".

In 1989 the CM-2 won the prestigious Gordon Bell Prize as the fastest machine on earth, winning both the "absolute" performance prize as well as the price-performance prize, and its successor CM-5 (with a very different architecture and package) won the Gordon Bell Prize in 1993.

 

Visual design of the CM-1/CM-2:

From 1983-1985 I directed the packaging and industrial design of the Connection Machine CM-1 at Thinking Machines Corporation, working with industrial design consultants Allen Hawthorne and Gordon Bruce, and mechanical engineer consultant Ted Bilodeau. The CM-2, released in 1987, was a more advanced successor (including floating point hardware) contained in the same physical package.

The form of the machine was to express both its function and the passions of its creators: the dream of producing a "Machina Sapiens," a new genus of living, thinking machines. For a description of the design history, theory and concepts behind the visual design, see my article:

Yale Professor David Gelernter wrote his impressions of the machine in 1998:

"There are, of course, first-rate designers at work today. There have even been heroes of computer design: The CM-1 and CM-2 parallel supercomputers of the 1980s, designed by a team headed by Tamiko Thiel, were elegant and fascinating. At Yale, visitors stopped by the machine room often to admire the thing just as sculpture." Gelernter, David. "Beyond the Grey Box," ID Magazine, Vol. 45 #2, March/April 1998, page 60.

 

Existing machines:

At its height, I have heard there were various Connection Machines (CM-1, CM-2, CM-2a, CM-200 and the successor CM-5 (in a completely different package design) at 70 installations around the world. The following machines have been preserved in museum collections:
