Re: Using thread-safe source_var/target_var to replace POINTER variables

Thank you. Yes, you've correctly interpreted the need for aggregating dipole measurements across various points. In fact, I was able to use that scheme in this line of code : self.dpls.append(h.Vector().record(dpp._ref_Qtotal)) I'm not sure what the computational cost is at each time step of recordi...

Using thread-safe source_var/target_var to replace POINTER variables

I'm working on making a simplified HNN model threadsafe so that I can turn on cvode.cache_efficient(1) for about a 30% performance improvement. However, some of the mod files that implement dipole recording use POINTER variables for (1) aggregation and (2) connect to voltages as inputs. Instead of P...
