Getting started

To use the HBP Neuromorphic Computing Platform you will need:

  1. an HBP Identity account (available on request)
  2. to sign the Platform User Agreement and return it to

Once you’ve received confirmation that access has been approved, head to the Platform home page and click on “Get started!”

This will create a new “collab” (a collaborative workspace) within the HBP Collaboratory, pre-loaded with the tools you will need to access the Platform. You can now:

  • Add team members to your Collab using the “Team” link in the navigation bar on the left. Only members of the team will be able to launch simulations. If this is a public collab, anyone with an HBP account will be able to view the results. If it is a private collab, only team members will be able to view results.
  • Read the Guidebook.
  • Request an allocation of compute time on the platform, using the “Resource Manager” link.
  • Run simulations, using the “Job Manager” link.

Request a compute time allocation

Using the Resource Manager form, request test access to the platform by entering a project title and a brief abstract explaining why you wish to use the platform. It is not necessary to fill in the “Project description” field.


After clicking on Submit proposal, your request should be approved within 48 hours. If you’ve received no response within this time, e-mail

For more information on compute time allocations, see Requesting access to the platform.

Run a simulation

Once your test allocation has been approved, click on “Job Manager”, then on “New Job. Select “SpiNNaker” in the Hardware Platform drop-down menu, then enter Python code in the “Code” text box, for example the following short script, which simulates a population of integrate-and-firing neurons with different input firing rates:

"""A population of integrate-and-firing neurons with different input firing rates"""

import numpy as np
import matplotlib.pyplot as plt
import pyNN.spiNNaker as sim

sim.setup(timestep=1.0, min_delay=1.0)

# create cells
cell_params = {
    'cm': 0.25, 'tau_m': 10.0, 'tau_refrac': 2.0,
    'tau_syn_E': 2.5, 'tau_syn_I': 2.5,
    'v_reset': -70.0, 'v_rest': -65.0, 'v_thresh': -55.0 }
neurons = sim.Population(100, sim.IF_cond_exp, cell_params)
inputs = sim.Population(100, sim.SpikeSourcePoisson, {"rate": 0.0})
# set input firing rates as a linear function of cell index
input_firing_rates = np.linspace(0.0, 1000.0, num=inputs.size)
inputs.tset("rate", input_firing_rates)

# create one-to-one connections
wiring =  sim.OneToOneConnector(weights=0.1, delays=2.0)
connections = sim.Projection(inputs, neurons, wiring)

# configure recording

# run simulation
sim_duration = 10.0 # seconds * 1000.0)

# retrieve recorded data
spike_counts = neurons.get_spike_counts()
output_firing_rates = np.array([value for (key, value) in sorted(spike_counts.items())])/sim_duration

# plot graph
plt.plot(input_firing_rates, output_firing_rates)
plt.xlabel("Input firing rate (spikes/second)")
plt.ylabel("Output firing rate (spikes/second)")

Leave the other text boxes empty, and click “Submit”. The job will be submitted to the queue, and will appear in the list of jobs with a “submitted” label. Unless the platform is very busy, this job should run within a few minutes on the large-scale SpiNNaker system in Manchester. Once the simulation is finished you will receive an e-mail, and on refreshing the job list the status will change to “finished”.

Once the job is completed, click on the magnifying glass icon to see the job results.


For more information on running simulations with the platform, see Submitting a simulation job.

Copy data to longer-term storage

The results of your simulation are now available on a file server attached to the SpiNNaker system. This storage is only temporary, however; after three months, your files may be deleted to free up space.

For this reason, therefore, we recommend either downloading the files to your local machine or copying them to longer-term storage within the Human Brain Project infrastructure.

For now we will copy the files to Collab Storage by clicking the button “Copy to Collab storage”.

If you now click on the link “Storage” in the left-hand menu, you will see the files produced by your simulation.
