Batch direct impact calculation in process

Question

I have an eco invent dataset, about 18000 processes and I want to calculate direct impact IPCC 2013 GWP 100a (incl. CO2 uptake). I get all process descriptors and loop throught the list, for each process I run calculation. The problem is it takes too long time. If a calculation takes 3s to finish, in total it would take about 15 hours. Is there any strategies? For example running the openLCA IPC server on different ports?

Answer 1

we have a really nice script to do this, it takes about 10 minutes for the entire ecoinvent database and writes calculation results to a file, you can execute it in openLCA; it is not free but worth it I think:
