[...] In this simple mode,wheather the worker(logic unit)must only have one?

According to what I understand, the master can connect multiple slave and  each slave can be runn on a different computer.  But In single master mode ,whether it contains only one Slave unit(or running only one slave  thread of excute) on a single computer.

Hello,

I guess you are speaking about this part of the documentation: https://staging.validation.linaro.org/static/docs/v2/first-installation.html#single-master-instance-installation

In this case, all components are on the same server. So lava-server *and* lava-dispatcher are installed on the same server.

I don't understand the question. Do you speak about workers or about DUT (device under test).
