Slow speed to save sim results
Posted: Sat Apr 21, 2018 10:32 am
Hi Salvador.
I'm saving the voltage traces of about 200 neurons, into a mat file, and the time to save them can be up to 3 time the total run time of the simulation. The file is saved at the same rate (about 2-3MB/s) on clusters and on workstations with SSD drives, and it is independent on the number of cores used to do the simulation. Is it normal?
I have seen on GitHub that you planned to implement a new parallel way to save the results. Is it something that will taken a lot of time to finish?
