Intro: Scheduling SIG – Da Ma, Huawei
In the past years, sig-scheduling incubated four projects to meet different scheduling scenario, e.g. batch workload, resource rebalance. We'd like to give an introduction for those incubator projects, so please join us for understanding of them. In this presentation, we'll give an introduction on its background, user case, tutorial and so on. We will also cover the feature interaction with kube-scheduler for better resource utilization. This session is most useful for cluster admins or those who want to start contributing to Kubernetes scheduler.

A
I'm
going
to
introduce
your
introduction
about
the
six
gardening
and
I'm
I'm
cows.
You
know
this
is
my
job
ID,
Twitter
ID
and
also
select
ID.
You
can
view
me
in
the
in
the
night-
and
this
is
my
email,
personal
email,
f
wrong
re
so
from
the
seek
scheduling.
I
think
this
is
our
chart
of
our
responsibilities
of
single
scheduling
and
highlighting
right
is
that
our
major
responsibility
is
to
is
a
pole
placement
decision,
so
a
user
caster.
A
We
are
going
to
have
our
opinion
poll
and
I
I,
don't
know
the
here
or
we
are
trying
to
find
some
way
to
have
a
better
decision
to
put
the
spending
proton
on
the
node.
You
know
there
is.
Another
topic
is
about
resource
a
plan
such
as
Dakota,
how
many
results
for
10
tester
should
be
used
and
whether
we
can
share
selves
between
different
tenants
for
such
a
for
this
topic
about
result
plan.
This
is
for
now.
This
is
a
note.
It's
a
lot
of
scope
of
six
scheduling.
A
It's
a
belong
to
the
API
machinery
there.
There
are
lots
of
history
over
about
this
part,
but
you
can
ping
us
in
the
night
and
we
would
like
to
also
have
some
involving
this
discussion
right
now.
Anime.
This
is
the
official
charter
for
sixth
gathering,
but
we
also
have
some
other
related
active
activity
in
the
community
part
yeah,
and
if
you
want
to
connect
us
I'll,
propose
some
idea
or
proposed
some
synergy
in
the
secret
six
scheduling
there.
A
There
is
some
way
to
to
ping
asked
now
the
first
one
is
all
we
have
a
weekly
meeting
here
when
this
meeting
as
a
one-by-one.
So
one
meeting
is
the
front,
is
really
Europe
and
the
u.s.
friendly
and
the
other
one
is
a
sure
friendly.
So
so
you
can
find
meeting,
you
have
fun
a
better
meeting
for
your
foil
time
zone.
A
Another
one
is
without
you,
leader
here,
young
Bobby
from
Google
and
the
other
one
is
catch
me
from
Huawei
right
now
and
we
also
house
like
and
mail
lists,
and
you
can
find
some
you
see
about
staccato.
This
is
the
major
commercial
waves
you
can
find
us
in
the
community
part
in
the
a
frantic
scheduling
at
the
at
the
beginning
of
the
single
scattering
we
focused
on
a
coop
scatter.
This
is
we
call
it
a
coop
scatter
or
default
scheduler
Oakham,
seeing
as
we
are
talking
about
it,
coop
scheduler.
A
This
is
an
our
major
sub
approach.
Out
of
this
see,
our
major
feature
I
implement
in
this
unit
is
per
sub
project
and,
as
this
subject
is
in
the
upstream
and
but
from
past
in
the
last
year
or
maybe
the
year
before
last
year,
we
find
more
and
more
workload.
Oh
cool,
a
growing
income
Linnaeus
now
the
first
one
we
a
single,
the
famous
one-
will
be
a
cool
flow.
There
are
lots
of
topic
in
in
comp
recently,
so
it's
a
motion,
leaning
motion
enumerated
workload.
Another
one
is
the
big
data
part
spark
right.
A
There
are
also
how
some
requirement
from
its
traditional
HPC
user.
This
logo
is
openmpi.
They
also
like
to
run
the
workload
the
incriminated,
so
we
need
to
support
such
candle
for
high
performance
or
close
up
actual
closure
brain
tails.
So
we
some
feature
is
a
static
head:
account,
scheduling,
fair
share
between
the
job
and
queue,
something
like
a
concept
we
incorporate
it,
but
because
of
contacts,
so
we
incubate
another
provider,
we
call
it
a
cool
back,
so
cool
patches,
the
batches
together,
are
focused
on
high
performance.
A
Workload,
belong
to
the
sick,
scheduling
power,
and
we
also
find
final
sum,
and
some
people
propose
another
program
Poseidon
because
of
they
we
have
some
paper.
They
have
some
way
to
get
a
better
throughput
to
place
the
boat
based
on
some
piece
on
the
graph
or
mean
cost
of
flow.
For
this
part,
so
there
is
a
another
project
on
another
way
to
place
the
protein
in
a
cluster.
A
There
is
also
another
sub
protractor
D
scatter,
because
the
when,
when
the
when
we,
when
the
window
PO
to
come
and
around
the
some
restrict
some
photo
find
here
or
and
he'll
find
a-
maybe
maybe
not
true,
so
we
knew
to
another
component
to
cry
to
that.
One.
So
I
will
introduce
the
one
by
one
of
this
of
those
project
Janna
to
see
how
they
work
together.
Yeah
now
the
first
one
is
a
coop
scheduler.
Now
cool
scatter
in
the
you
know
default.
A
This
is
the
default
scheduler
of
Reuben
Hayes
and
in
the
years
gatherer
be
it
how
work
you
and
it
will
handle
about
one
by
one.
Yes,
from
every
time
it
will
pop
up
one
pody
I
need
to
I
need
to
find
a
house
in
the
tester
when
it
find
it
code
in
the
cluster.
If
we
would
do
two
major
phase
now,
the
first
one
is,
we
call
it
predicts.
Predicts
means
some
node
cannot
feed
those
requirements,
such
as
we
want
to
run
some
ho-dong.
Some
special
note.
A
Yes,
that
has
no
letter,
no
defiantly,
something
like
that
so
for
in
this
part,
is,
will
only
identify.
Furthermore,
in
this
use
a
picture,
no
one
I
don't
know
Dan,
not
we
can
always
get
you
Paulo
to
denote
one
another
yeah
over
two
three
four
available
candidates
for
this
poet,
so
the
other.
The
second
phase
is
how
to
choose
a
one
for
for
the
note,
so
we
will
have
a
several
policy
to
get
one
skarphol
for
the
note.
So
for
the
notice
we
have
work.
I
do
missing.
A
A
Another
one
is
a
pullback
here,
cool
badge
focus
on
the
back
chest,
cavity
yeah
and
maybe
some
resolve
the
sharing
between
the
different
tenants
and
his
top
priority.
The
patches
together
result
sharing
between
10
and
so
there's
a
you're,
a
big
story
for
in
the
kubernetes.
So
as
soon
as
this
is
a
really
low
priority
it
for
for
now,.
A
Coops
granular
coop
acts
right
now
is
coops
caterer,
but
there
are
also
some
other
enhancement
cross.
Dr.
Brennan
is
no
such
as
a
data
management
such
as
a
data
locality
and
their
preload,
and
something
else
and
some
isolation
in
the
node,
and
we
are
going
to
have
some
new
content
around
time
for
for
them
before
for
them
hosting
right
here
for
HPC
yeah,
and
we
also
need
to
have
job
management
to
amendment.
A
It
means
for
them
or
multiple
pull
the
template
in
the
unit
role
for
motion
in
your
job,
for
example,
what
you
have
drop
they
have
our
pas.
They
have
workers,
they
have
a
different
the
power
template,
but
for
the
for
the
job
in
the
core
part
is
it's
only
support
of
one
for
the
templates.
I
just
mean
I
really
bought
is
a
it's
all.
The
power
use
the
same.
We
made
it
here
yeah
and
we
also
needed
to
support
to
some
accelerators
such
a
GPO
FPGA,
something
like
some
new
hardware.
A
A
This
is
overall
in
the
cool
back
edge,
so
we'll
dump
everything
or
are
we
polled
and
in
year
four
into
the
cool
back
so
is
here
is
a
so
you
can
see
everyone.
We
were
down
into
the
cash
and
there
will
do
several
action
here.
The
auction
is
predicts
a
lock,
well
locate
the
under
preemption,
maybe
some
back
filter
later
the
and
the
ocean
is
real
comfortable.
A
You
can
change
the
order,
you
can
disable
someone
for
them
or,
if
you
don't
need
to,
if
you
don't
need
to
prompt,
you
can
just
enable
predicts
and
a
lock
it.
It
will
make
sure
you
there.
You're,
no
boat
will
be
evicted
and
there
are
also
house
unpacking
here.
So
you
can,
you
can
choose
which
program
you
are
going
to
use.
A
We
already
have
equipment
in
the
upstream,
yes
such
as
cost
carrying
as
a
as
it's
a
similar
to
come
scheduling,
because,
oh,
we
have
some
renamed
early
of
this
year.
Yeah.
We
also
house
with
the
cost
scheduling
is
we
have
designed
ultimately
in
the
upstream,
and
we
are
going
to
migrate
to
this
feature
from
cool
packs,
choose
a
default
scatterer.
A
The
other
was
there
also
have
some
other
features
for
for
the
for
the
patch
yarnís.
The
second
one
is
the
fair
sharing
between
the
draw
beyond
between
the
queue
we
have
her
share.
I
mean
for
alumni
only
want
to
use,
have
have
class
her
results
in
this
culture
and
the
other
have.
This
also
will
share
to
z,
to
the
other
draw
in
the
unity
fall
schedule.
We
cannot
do
that
right.
A
So
if
the
first
char
immunity
can
share
the
results
between
the
different
between
a
different
job
in
the
pasture,
so
the
other
one
is
the
preemption
yeah.
This
is
the
same
work
together
with
a
fair
share
to
make
to
to
share
is
also
between
to
to
share
cluster
between
the
jobs,
and
there
are
also
some
a
task
about
Tesla
priority
which
isn't
wrong
because
of
some
some
tall,
some
tasks
convincing
job
dependencies
that
share
the
spot.
Where
were
an
ass
pocket
scooter?
We
need
to
make
sure
the
results
always
kill.
A
Trevor
in
studio
for
is
kilter
in
the
currently,
as
the
spark
and
the
sparking
an
uncommon
is
use,
it
will
started
drug
war
and
is
in
the
driver
to
start
a
skill
turn
to
the
so
such
kind
of
dependency
program.
I
think
it
can
be
has
with
in
the
schedule
/.
Yes,
it's
also
use.
The
pod
predicts
similar
to
the
default
scatter.
It's
just
a
import,
I
read
predicts
into
the
coop
at
right.
Now.
It's
also
support
you
backfill
and
a
dynamic
configuration.
A
All
this
feature
is
I
think
this
is
in
the
experimental
level.
So
you
can
try
this
one
and
give
us
feedback.
We
will
keep
enhancement
that
and
the
issue
is
that
we
I
didn't,
propose
the
detail
to
the
upstream,
so
the
API
may
be
change,
and
maybe
it'll
be
here
or
maybe
change.
So
you
can
try
this
one
and
we
I
will
summaries
as
the
feedback
and
propose
the
detail
to
the
upstream.
So
we
can
migrate
to
this
feature
one
day,
one
to
the
lab
scream,
yeah
I.
A
Also
often
another
issue
choose
in
the
upstream,
that's
mean
that
bring
back
have
ability
into
criminal.
Yes,
so
I
was
seeing
in
the
previous
page
includes
all
management
data
management
everything's
here,
who
you
call
this
included
this
issue.
I
will
do
this
one
by
one
and
and
and
a
1-1
to
contribute
you
can
you
can
check
this
one,
and
we
were
summary
most
things
here
over
here:
yeah,
the
other
sub
project,
as
is
a
Poseidon
Poseidon,
is.
A
It
tried
to
choose
a
scattering
in
a
different
way.
It
will
have
a
graph,
so
each
each
age
will
be
will
have
a
cost,
so
it
will
find
the
minimum
cost
of
flow
in
the
unit's
craft
of
the
overhaul.
Pastor
pizzette,
don't
give
a
adapter
from
from
the
urban
areas
to
the
firmament.
So
in
the
firmament,
Furman
is
another
another
community
you
can.
You
can
check
in
the
in
deny
that
in
the
in
tonight
yeah
you
know
for
the
firmament
and
for
the
posit
only
in
the
Google
Group
there
we
have.
A
A
Sometimes
we
hear
we
can
use
some
in
some
scenarios,
so
you
can
have
work,
try
to
find
if
can
walk
about
her
vanity
Falls
gatherer
yeah.
Another
one
is
a
default
Prasad
on
didn't
support
our
we
feature
in
the
compared
to
the
default
scatter
its
supporters.
Just
to
some
some
predicts
that
rather
know
the
level
of
NT
and
opposed
level
of
aunty
and
tan-tan
toleration
yogi
for
the
scatterer.
A
With
how
stable
scatter
here
and
always
some
people
always
ask
well
how
how
does
the
scheduler
work
together?
Yes,
we
have
coop
ash,
we
have
what,
if
all
scatter
and
we
helped
a
settle,
a
sink
master
is
a
I.
Don't
know
I,
don't
know
yes,
but
wait,
but
we
do
how
some
optional
proposed
here,
because
I
don't
know,
because
only
the
default
scheduler
is
a
production
ready,
the
other
three,
the
other
together
as
a
as
an
incubator
product,
not
the
first
one
who
bashes
the
other
is
a
potato.
A
So
we
don't,
so
we
don't
have
chance
to
consider
how
they
work
together.
Yes,
because
the
other
one
is
an
incubator
project,
our
focus
on
to
make
a
Kelly
now
feature
and
make
it
a
stable.
So
we
are
going
to
consider
hole
this
to
schedule.
All
this
together
will
going
to
work
together,
but
we
have
some
option
here.
The
first
one
is.
A
Differences
together
own
different
note,
so
you
for
them
were
a
few.
How
about
you
just
submit
opposed
to
the
scheduler
one
or
two
scheduled
to
so.
There
will
be
no
resource
conflict,
no
decision
conflict
here,
but
the
problem
is,
as
you
know,
one
another
to
is
the
idle.
The
just
gather
to
cannot
use
so
some
resource
will
be
the
resource
utilization.
Maybe
not
not.
Will
ya
not
good
enough.
The
second
one
is,
as
the
default
implement
implementation
of
mattes
together
how
we
resolve
the
registration
conflict?
A
A
There
were
me
how
conflict,
so
the
cube
later
will
reject
the
later
one
yeah
in
in
the
photo
long-running
surveys
or
the
photo
service.
Vocalizing.
That's
fine
because
the
photo
services
they
will
come
bTW
wrong,
really
a
long
time
for
one
day
or
two
days
so
reschedule
it
is
acceptable
right,
but
for
the
actual
clothes
that
root
beer,
there
will
be
a
challenge
with
two
theory
for
lumber
for
the
for
the
default
schedule
for
actual
hello.
They
can't
be
wrong
just
one
or
two
minutes.
Yeah
you
keep
rescheduled.
A
This
will
be
really
challenging
to
theory.
Another
big
issue
is
that
for
the
count
scheduling
they
need
to
offer
them
or
for
MPI
workload,
they
need
to
all
pose
to
start
together.
If
one
decision
will
reject
the
whole
company
to
reschedule
together,
this
will
be
reviewed.
Real
challenge
to
the
to
the
backscatter,
really
challenge
for
the
back
wall
load,
I,
think
yeah.
A
A
How
I
will
make
a
decision
which,
which
is
scatterer,
are
going
to
use
which
node
or
which
part
of
no
caster,
but
this
is
also
how
some
easy,
oh
here,
is
that
pole
house
they
were
requirement
to
the
to
the
note
for
them
or
noted,
although
finding
haste
gather
powder
find
a
something
all
these
things
so
to
the
Buddha's.
Travel
may
not
make
a
good
decision
choose
to
the
scatterer,
rather
so
otherwise,
I
need
to
know.
A
I
was
in
here,
so
I
think
the
options
three,
maybe
just
obviously
here
but
I-
don't
think
that
we
are
going
to.
We
are
going
to
do
this
to
option
the
other
option
to
also
plan
for
is
that
we
will
like
to
combine
everything
we
want
together.
Yes,
this
is
what
we
are
going,
a
single
s
it.
What
what
I'm
going
to
do
here
because
of
the
effort
again,
the
timeline
in
the
over
here
for
is
that
we
are
going
to
migrate
feature
one
by
one
to
the
defaults
together
right,
defaults.
A
Caterer
also
has
some
some
has
magnitude
for
the
black
ball.
For
the
more
we
have.
We
are
going
to
have
a
schedule
framework,
so
you
can
implement
some
something
or
some
probably
to
the
defaults
caterer
to
making
extendable
I.
Think
the
biggest
challenge
for
us
is
that
the
defaults
together,
I
didn't
have
drop
concept
right
now,
so
we
are
going
if
we
want
to
support
a
batch
workload,
support
a
job
of
scheduling
or
such
other
fair
share,
which
is
a
different
table.
We
are
going
to
introduce
the
central
concept
in
the
default
scatter
yeah.
A
No,
we
are
going
to
implement
some
some
cue
or
something
in
the
default
scheduler
to
suppose
that
they
are
coming
to
earth
or
challenger
for
us,
but
as
at
least
for
now,
we
are
going
to
use
this
direction
quite
firm
order
more.
This
feature
my
greatest
feature,
one
by
one
to
the
default
gatherer
yeah
and
actually
enhancing
the
scattering
of
umbrella
to
a
support,
a
different
kind
of
world
yeah.
A
Here
is
a
some
you
to
care
so
fruity
scheduler
and
also
for
someone
I
think
this
is
try
to
balance
the
workload
in
the
node
because
of
for
the
for
the
photos
together,
it
can
only
can
make
the
decision
when
the
polio,
depending
when
node,
are
running
a
student.
It's
just
an
even
ology
run
import
here
as
you
didn't
care
or
didn't
we
rescheduled
the
running
pod,
so
so
it
needs
another
separate
component
to
trigger
such
cannibal
rescheduling.
So
here
this
is
the
major
target
of
the
major
respond
bed
he'll,
the
disc,
a
dinner.
A
The
second
one
is
the
some
scheduling
decision,
maybe
not
true
anymore
I.
Think
the
one
example
is
that
profanity,
for
example,
poll
put
a
one
to
run
together
with
the
pot
be
so
this
title
polo
fennel
tea
and
these
getting
to
the
same
poll
right
now,
but
unfortunately,
the
Polybius,
the
keyword
person,
but
some
others,
but
should
the
Padre
I
didn't
know
that
and
the
default
scheduler
will
not
risk
a
tea
with
the
paw
day,
because
Polly
is
Ronnie.
I
just
think
everyone
is
it's
good.
A
Some
of
the
other
plan
is
no
they'll
sell
the
Anna's.
Something
is
the
mood
to
the
other.
No,
yes,
Capote
is
a
proton
one,
no
there's
a
killed,
so
the
poi
is
a
imaginary
schedule
to
the
other.
I
don't
know,
and
when
is
noted
by
defaults
together,
we
nod
to
that.
Moon
is
positive
to
the
Larry
Stoddard
couplet.
Let's
will
be
you
know
some
kids
village,
when
you
keep
keep
upgrading
the
node
I,
really
thought
we'll
move
to
some
small
or
to
some
to
the
no
being
a
small
group.
A
Yes,
let's
do
this,
this
part
of
group
who
are
really
high
workload
and
the
are
one
is
the
idol.
So
if
you,
after
several
time
after
upgrade,
you
run
a
schedule,
we
will
have
to
move
this
poll
to
the
to
the
Idaho
to
the
other.
Node
yeah
you.
So
this
is
some
some
policy
and
some
strategy
for
the
food
kiss
caterer
to
do
a
now.
Some
on
the
first
one
is
a
remove
duplicate
and
the
second
one
is
the
low
note
heat
euthanization
just
mean.
A
It
didn't
it
didn't
know
that
I
will
it's
harmful
for
ADA
to
reschedule
report,
so
just
gather
will
do
a
lot,
but
the
the
this
scheduler
will
knowledge
will
have
some
some
restriction
to
irrigate
suppose
now.
The
first
one
is
a
create.
A
polar
ice
will
not
care
about.
There
is
a
boat
I
think
that
this
restriction
will
be
remove
later
because
create
a
book
out
critical
critical
boat
will
be
replaced.
A
bad
and
preemption
I
think
that
this
would
be
a
great
approach
which
I
will
be
removing
one
hour
to
release
so
for
this.
A
For
this
part,
I
think
this
is
just
for
justa
2k
backward
compatibility
with
that.
The
other
one
is
is
a
pod
with
as
another
part
of
our
C's,
that's
mean
some
marrapodi
and
some
standalone
mode
because
of
for
disk
address
when
it
would
depend
on
the
controller
to
risk
to
recreate
the
poll
right
for
our
3
4
4
RS.
It
will,
if
polio,
create
killed.
The
controller
will
reschedule
it
recreate
it,
but
for
some
standalone
or
static
or
marrow
pod,
no
one
can
create
that
one.
So
a
food
discarded
work
you
ready
to
kill.
A
Oh
I,
don't
think
this.
We
need
to
call
the
coil
should
be
deleted.
We
don't
how,
in
the
you
know,
criminals
right
now
for
the
deleted.
The
ponies
come
right.
No
one
can
recreate
the
bone
so
for
this
category,
I
only
care
about
how
our
owner
here
some
controller
here,
yeah
yeah,
the
other
one,
is
a
demon
site,
demonstrate
we'll
start
the
pod
on
each
node
right.
So
this
scatter
will
not
to
try
to
evict
him
aside
pause,
because
actually
it
will
reschedule
the
foundation
on
this
node.
A
This
nothing
would
change,
so
it
didn't
linear
to
two
V's
design.
The
other
one
is
local
storage,
because
the
it's
need
to
use
the
local
storage
here.
So,
as
we
I
think,
the
controller
will
also
reschedule
the
polar
to
this
node
to
this
node.
When
it's
a
startup,
the
other
one
is
some
pest
I
propose
it
will
be
kill
first
rate
because,
as
its
didn't
buy,
the
voice
is
a
really
low
priority.
Fearsome
yeah
yeah,
it's
real!
A
Never
you
very
emotive,
it
afraid
to
break
a
peep
pdb
code,
disruptive
baggage-
yes,
because
it
making
sure
the
the
service
will
be
stable
here.
Yeah
I
think
this
is
oral
through
of
my
introduced
about
scheduling,
control,
go
through
the
each
sub
approach
out
here
and
we
are
going
to
have
a
gift
I'll
about
our
schedule
and
sick
I.
Think
tomorrow,
yeah,
so
Bobby
will
give
a
deep
dive
about
our
sick
and
you
can.
You
can
join
this
decision
for
this
one
for
more
details
about
default,
scatter,
yeah,
okay,
some
case,
so
this
offer.
A
B
A
For
this
thing,
I
think
I'd
like
to
maybe
you
I
think.
Oh
you
can
openly
this.
You
here
describes
the
kick
to
user
scenario
and
what's
the
problem
we
are
going
to
resolve
and
we
are
going
to
how
whether
this
is
should
be
a
a
protractor
foldable
to
the
default
schedules
to
some
other
product
or
whether
we
should
start
or
another
sub
project
to
for
this.
For
this
in
our
oh
yeah.
D
A
A
A
A
Yeah
yeah
I
think
that
you
can,
if
there
I
know,
I
know
I
know,
djinji
TOCOM
have
something
more
about
this
report,
because
I
can
say
briefly
back
about
this.
One
I
think
if
we
can
have
if
you
can
share
some
logs,
some
were
compelling
here.
This
will
be
how
Bobby
Oh
have
helped
us
to
identify
the
various.
A
key
point
of
right
now
for
for
currently
awful
for
our
work
right
now
is
as
a
tried
to
define
identified
with
it
very
important
ID
to
the
default
scatterer.
This
need.
A
A
B
B
A
button
that's
generating
pods
to
do
it,
work,
no
I,
don't
want
the
first
thing
that
I
said
to
the
cluster
to
know
we're
at
the
clusters
out
of
capacities.
The
first
thing
doesn't
run
and
later
there's
a
pasty,
but
it's
other
things
that
are.
You
know
there
are
other
things
that
come
in
behind
it
fill
up
the
space.
A
A
We
don't
help
offensive
right
now
asserted
can
on
the
operator
to
told
us
and
as
far
as
I
know,
some
hookah
flow
operator
to
simracing
is
that
when
one
pole
is
finish,
they
start
the
at
the
other
one.
Yes,
they
suppose
I'm
not
sure
yo
case
is
a
4/4
workflow
or
justice.
Some
someone
have
a
higher
priority
to
use
it
as
the
results.
