I’ve py frontend that calls something like `julia -e "runmyapp()"` which exits upon completion. Is there way to reuse such sessions? My julia program takes minutes to compile which gets repeated. Thanks!

You can try: [GitHub - dmolina/DaemonMode.jl: Client-Daemon workflow to run faster scripts in Julia](https://github.com/dmolina/DaemonMode.jl)

Or make your script a package and have it precompiled.

Alternatively, use JuliaCall, to interface with Julia without running it externally.

Thanks we used PackagePrecompiler b4 but it’s a little buggy. DaemonMode looks interesting but criu seems even simpler. Related question, is there a way to keep alive `julia -e "f(args1)"`? I want to reuse that process to execute f(args2) because it already compiled f.

I guess DaemonMode kinda answers my question. will try using criu on DaemonMode
