1 i’m not sure about that but seems `RemoteException` type is for this purpose, maybe you can refer to julia manual here [Distributed Computing · The Julia Language](https://docs.julialang.org/en/v1/stdlib/Distributed/#Distributed.RemoteException)

2 you can use `Distributed.map_pid_wrkr` function to map the pid to a `Worker` type, then you can lookup the hostname, such as `Distributed.map_pid_wrkr[pid].config.host`. `config` field is a `WorkConfig` type, and all field name can be obtained by `using Distrbuted; fieldnames(WorkerConfig)`, that is `(:io, :host, :port, :count, :exename, :exeflags, :userdata, :tunnel, :multiplex, :forward, :bind_addr, :sshflags, :max_parallel, :connect_at, :process, :ospid, :environ, :ident, :connect_idents, :enable_threaded_blas)`.
