Parallelisation of the runs in the parameter study fails because the ensemble_results of the individual ranks are all sent at once due to an Overflow of the Int value bytes_size.
The maximum capacity is quickly reached if the flows are also to be saved. In my case, I use the Secir model with tmax = 250.
Just the flows have a size of 72mb per run (dim 400 [# Counties] * 250[# Days] * 15[# Flows] * 6 [# Age groups] * 8[size double])
Version
Linux
To reproduce
Save the flows + results in the results processing function and do 150 runs with tmax=250.
