[Buildbot-devel] custom scheduler for parallelism

[Greg MacDonald]

Hi Everyone,

I have a few jobs that are good parallelism candidates in that several console commands can be split up between machines. I've got some basic parallelism with the triggerable scheduler and multiple builders, but I have to make a builder for each machine, which means I have to divvy up the commands in advance. I would much prefer a more general solution where I dynamically start a multiple instances of a single builder with each instance having a different command to run. This way the nodes are kept general and the load can be spread around the cluster dynamically. Is there a way to do this that I'm not aware of? It doesn't seem like things are setup this way so I was thinking of extending the triggerable scheduler to do this, using the build properties to pass the command to run. Does this sound like a reasonable course of action? Thx.
