Package: boinc-client
Version: 5.8.17-1+b1
Severity: wishlist
Tags: patch
I have attached a patch to the init script to make the boinc client
(and children) get scheduled with more advanced schedulers if available
and if the schedtool package is installed. It first tries idleprio,
then batch, and falls back to nice if neither of those is available.
It also tries to schedule the IO to batch using the ionice command if
that is installed.
I also added a print out of current scheduling to the status command.
The advance scheduling makes the boinc computations interfere as little
as possible with current operations, even less so than using nice does.
The while loop waiting for the pid file may seem like overkill but I've
had a couple times where it took a little while for the pid file to
show up.
