SpiNNaker

SpiNNaker (spiking neural network architecture) is a massively parallel, manycore supercomputer architecture designed by the Advanced Processor Technologies Research Group (APT) at the Department of Computer Science, University of Manchester.[2] It is composed of 57,600 processing nodes, each with 18 ARM9 processors (specifically ARM968) and 128 MB of mobile DDR SDRAM, totalling 1,036,800 cores and over 7 TB of RAM.[3] The computing platform is based on spiking neural networks, useful in simulating the human brain (see Human Brain Project).[4][5][6][7][8][9][10][11][12]

The completed design is housed in 10 19-inch racks, with each rack holding over 100,000 cores.[13] The cards holding the chips are held in 5 blade enclosures, and each core emulates 1,000 neurons.[13] In total, the goal is to simulate the behaviour of aggregates of up to a billion neurons in real time.[14] This machine requires about 100 kW from a 240 V supply and an air-conditioned environment.[15]

SpiNNaker is being used as one component of the neuromorphic computing platform for the Human Brain Project.[16][17]

On 14 October 2018 the HBP announced that the million core milestone had been achieved.[18][19]

On 24 September 2019 HBP announced that an 8 million euro grant, that will fund construction of the second generation machine, (called SpiNNcloud) has been given to TU Dresden.[20]
