Simulator
How do we replicate the issue/how would it work?
Run on cerberus. Produces following output:
Done with simulation cycle, beginning growth update 312
Updating distance between frontiers...
computing areas of overlap
out of memory in ./Connections/ConnGrowth_d.cu at line 34

Nee to check whether the out-of-memory condition is occurring on the CPU or GPU side. Also need to check that it's not just caused by the fixed upper limit on number of synapses per neuron (needed to allocate memory on the GPU side). Assuming that it's really running out of GPU memory, the next step would be to use two GPUs, which of course gives twice as much memory.
