NetPyNE batch simulation problem: Unable to run whole params at one time.

[Da Som Choi]

Hi all,

I am practicing batch simulation with NetPyNE tutorial 8 and trying to implement batch simulation into my code. 

When I run the tutorial 8 with six cores, only six results come out even though the number of cases is 9 (3*3 = 9 from params['synMechTau2'] and params['connWeight']).

The remaining three results come out when I run a second time. Is this how batch simulation works? I expect that each core runs the main script (init.py) and keeps running with all combinations from params (nine results would come out at once).  

A similar problem happens to my code; The number of results is the same as the number of cores I set up, but in this case, even though I run a second time, they keep giving me the same results, not going to the next iteration. 

If someone has experienced the same issue, I'd appreciate your help!

Thank you.

Best,

Da Som

Hello,

Are you running with the "mpi_direct" method or the "mpi_bulletin" method? It seems that the latter is more prone to mpi dependent quirks (or how it executes varies between what version of mpi is installed).
