[Barrelfish-users] FW: How to write a self-replicating service

[Georgios Varisteas]

Hi again,

Let me make this question a bit more specific. I would like to know what is the best alternative to spawn() in usr/spawnd/service.c that allows a process to spawn a new process on any core other than it's own? Also I would very much appreciate any info on the "char *const envp[]" argument, as what is provided (in other source files) is not really informative. Is it safe in my context to inherit the environment by passing NULL?


Thanks in advance,
Georgios Varisteas

Hi,

I would like to ask for the appropriate methodology (API-wise) and structure to use for a service which, when run on a core, will automatically spawn other instances of itself on other cores (not necessarily all available)? A perfect, already implemented example is the monitor. However, by looking into its source code I couldn't get a generic methodology, so i though to ask here before basing my code on the wrong assumptions.

Also, what do the initials BSP [core] stand for?

Best regards,
Georgios Varisteas
