Number of spikes decrease in parallel run
Posted: Mon Jun 06, 2016 12:09 am
Hi,
I have tried to compare serial and parallel versions of my network code. In parallel run, as the number of processes increased, the total number of spikes decreased. Let's say, with np 1, total number of spikes observed is 58000 and with np 2, the number of spikes decreased to 38000. In the serial run, I get total number of spikes as 58000. With np 4, the number of spikes observed is 8000.
I have checked if the postsynaptic neuron is receiving same connections as in serial run and it's the same. But I couldn't figure out how the spikes are lost.
Is there a way to debug this kind of problem? Kindly let me know.
Thanks in anticipation.
