J–Machine
The J–Machine (Jellybean-Machine) was a parallel computer designed by the MIT Concurrent VLSI Architecture group in conjunction with the Intel Corporation. The machine used "jellybean" parts—cheap and multitudinous commodity parts, each with a processor, memory, and a fast communication interface—and a novel network interface to implement fine grained parallel programs.[1]
History
The J-machine project was started in 1988 based on work in Bill Dally's doctoral work at Caltech.[2]
The philosophy of the work was "processors are cheap and memory is expensive," the J in the project's title standing for jellybean which are small cheap candies. In order to make use of large numbers of processors, the machine featured a novel network interface using message passing.[3] This allowed a node to send a message to any other node within 2 microseconds.[4]
Three 1024-node J-machine systems have been built and are kept at MIT, Caltech and Argonne National Laboratory.[5]
