94d01414bb4813b29be3713a60b0b54b06001a30 cmd/coordinator, dashboard: remove some trybots, shard others wider
I'm aiming to have trybot runs finish in under 5 minutes.
This CL removes openbsd-386-gce58 and freebsd-386-gce101 from the trybot set.
openbsd-386-gce58 is the slowest builder. It has an average speed of
722 seconds (and 95 percentile of 923 seconds) over the past week, and
that's sharded over 4 machines. Too slow. It's not worth the resources
to keep it as a trybot. It hasn't caught any interesting bugs. This
builder will still run, but not as a pre-submit trybot.
freebsd-386-gce101 is not slow, but we're removing it to shift its
resources to shard other builders wider.
The coordinator now supports varying the build sharding width based on
whether a build is for a trybot or not. This CL defines separate
numbers for each, sharding builds wider as needed for some trybots.
freebsd-amd64-gce101 goes from 4 to 5 machines in try runs, and down
to 3 when not in try runs.
linux-amd64-race gets one more machine during try runs, and one fewer
in regular runs.
linux-arm goes from 7 machines always, to 3 or 8, depending on whether
it's a try run.
openbsd-amd64-58 goes from 4 to 3 or 6.
windows-amd64-gce goes from 4 to 2 or 6.
windows-amd64-race goes from 4 to 2 or 6.
darwin-amd64-10_11 goes from 3 to 3 or 4.
I'll see how these do over the next few days and readjust as needed.
Also in this CL: fix the constants for the expected duration of
make.bash, which impact when we schedule the creation of test sharding
helper buildlets. We were creating them too early before, wasting
resources.
