I used the parallel computing package in my app, like "doParallel" and "parallel", everything worked well when I run on my local computer. However, when I tried to deploy the app on shiny.io, something was wrong. How can I run parallel computing code in shiny.io? Thanks

I don't think you'd have to do anything special.
