Hello, I’m looking to be sure that a model will fit on a Loihi before I send it to the hardware. The Kapoho Bays we use either have 1 or 2 chips.
There are two limitations I am aware of that I could potentially check for:
number of neurons
number of synapses
number of neurons I can get from the nengo_loihi nengo.network.n_neurons
The limit is 131072 per chip
the number of synapses is d1 x d2 where d1 and d2 are the dimensions of each connection transform matrix. Sum those up for each connection in the network.
The limit is ~1,000,000 / 8 see (Trying to Understand Network Restrictions)
Any other thoughts or suggestions as to how to check a network will fit on 1 or 2 Loihi chips?
We found this which will print out the number of blocks
API reference — NengoLoihi 1.1.0.dev0 docs
But I’m not sure how to translate # blocks into # chips.
