How to run tasks in parallel for a large output in argo?

Question

I have a large list-output and would like to run a separate task for each entry. For small outputs I can use below template. But If I increase output, e.g.

for run in {1..100000}; do

it crashes. How can I solve this problem? I tried to use artifacts, but for artifacts I cannot iterate elements of a list.
