Okay,
I
mean
there's
a
little
bit
of
a
like
a
difference
because
we
had
a
North
America
first
and
so
there's
like
a
majority
of
topics
proposed
there
and
then,
like
you,
know,
EU
and
Asia
add
some
of
the
like
leftover
topics.
But
this
time
mrs.
Khan
Asia
gets
first
choice
at
all
the
good
topics
so
like
there
may
be,
some
people
are
holding
out
to
submit
there's
for
north
america
or
EU,
but
people
that
just
want
to
present.
Wherever
about
mrs.
topics,
you
know
we'll
get
a
good
chunk
of
them.
M
J
Think
we're
in
good
shape,
yeah
cuz
yeah
cuz,
like
yeah.
There
are
some
issues
in
in
Asia
because,
for
example,
the
website
there
are
in
English,
so
some
Sun
like
Chinese
speaker.
They
might
not,
they
might
understand
a
lot
on
technology
and
they
might
have
been
using
lasers
for
a
long
time,
but
they
cannot
like
write
up
a
proposal
in
a
very
good
way
in
English,
so
calamity
links
foundation
on
the
ascent
version.
Do
we
expect
them
to
present
in
English?
J
H
B
C
Okay,
can
you
guys
see
my
screen?
Yes,
yeah?
Okay,
great
so
I
want
to
talk
a
little
bit
about
hierarchical
roles,
which
is
a
feature
that
we're
building
in
maize
us
right
now
so
background.
What
our
role
is
amazed
us
people
should
be
pretty
familiar
with
this,
but
it's
one
of
the
basic
things
to
use
for
a
reason,
resource
allocation,
so
frameworks
redditor
enrolled.
C
But
we're
good,
okay,
so
mazes
uses
rules
as
part
of
how
it
allocates
resources.
So,
though,
frameworks
richer
in
a
role
and
we
offer
resources
to
individuals
in
a
fair
share,
akad
RF
minute
role
within
a
role
if
they're
multiple
frames
in
one
rule,
they
are
also
offer
resources
on
a
fair
amount,
and
then
you
can
set
weights
to
control,
basically,
a
fair
sharing
behavior
between
roles,
so
by
default
a
role
has
a
weight
of
one.
If
you
increase
its
late,
it
gets
a
larger
share
of
the
treasure.
C
C
So
right
so
partying
rules
it's
using
to
model
organizations.
So
within
you
know,
so
the
pen
organization
consists
of
several
teams.
Let's
say
engineering
and
accounting.
You
might
want
to
give
certain
amount
of
guaranteed
resources,
quota,
more
fair
shipping
weight
to
one
team
or
another
team.
So
you
want
to
control
how
accounting
and
engineering
use
the
resources
of
cluster
in
real-world
organizations.
C
They
often
consist
of
prior
cases,
multiple
levels
so,
rather
than
just
having
engineering
accounting,
you
might
have
engineering
consists
of
several
sub
teams
each
other
to
my
also
consist
of
more
sub
genes.
So
there's
no
they're
not
directly
support
for
this
inertial
cookie
involved
in
the
role
system,
so
one
minute
to
try
to
solve
this
problem
with
a
few
essentially
use
roles
to
represent
all
the
leaf
right
to
that
hierarchy.
So,
for
example,
supposed
to
mean
we
had
ends
which
consisted
of
a
front-end
team
and
analytics
team.
C
If
we
knew
somewhere
that
you
know,
we
want
in
general,
should
have
a
certain
weight
within
and
runners
at
provide
those
shoes
were
suffering
from
tended
analytics.
We
could
basically
take
all
those
leaf
roles,
so
in
this
case
and
front-end
and
Jenna,
lytic,
accounting
and
so
on,
basically
figure
out
okay,
given
how
we
want
those
organizations
to
compete,
resources.
How.
C
Resources
to
the
team's,
what
property
through
his
head
on
the
teams-
and
that
would
you
know
mostly
work
but
I.
You
know
as
two
main
problems:
the
first
that
it's
red
robin
so
anytime-
that
you
change
the
weight
on
any
one
of
those
teams.
You
might
need
to
change
the
weight
on
you
harkee
on
the
entire
set
of
lead
roles.
C
The
second
is,
it
doesn't
allow
about
delegating
so
we'd
like
to
support
the
notion
that
you
can
have
sort
of
a
sub
off
a
seven
min
serve
operator
that
is
granted
resources
by
the
cluster
operator
for
say
the
end
jority.
Let's
say
the
person
who
runs
our
engineering
they're,
given
a
bunch
of
resources
to
use
as
they
see
fit
within
the
intramural
organization,
and
they
should
then
be
able
to
dedicate
our
hand
out
those
resources
I'm
to
the
sub
teams
below
engineering.
So
maze
has
only
supported
this.
This
flat
list
of
rules.
C
It
wouldn't
be
possible
to
support
this
workflow,
so
instead,
what
we
want
to
do
is
add
a
note
returning
to
the
role
system.
So
it's
basically
the
idea
at
that
one
rule
can
be
a
child
role
of
another
role.
So,
let's
and
then
we
went
extend
weights
reservations,
quota,
an
authorization
to
support
this
hierarchical
relationship
between
roles.
So,
let's
see
how
that
would
work.
So,
let's
talk
about
how
we
do
in
the
basic
allocation
scheme,
which
is
to
say
that
a
rule
that
you
know
we
now
have
rules
that
can
have
sub
rolls.
C
To
engine
a
large
amount
of
resources
to
accounting,
then
within
front
end
with
an
end,
we've
done
a
much
higher
way
to
analytics
in
a
much
lower
weight
to
front
ethical.
But
the
important
point
is
that
that
weight
of
10
for
into
analytics
only
controls
within
n
JH
who
gets
those
ends
resources.
So
in
this
case,
counting
would
likely
actually
get
more
resources
than
ang
analytics.
Even
though
those
wait
on
androids
is
actually
higher
than
the
weight
on
account
over.
C
So,
roughly
speaking,
how
would
you
know
how
would
we
think
about
implementing
answer?
How's
it
going
to
work?
The
basic
idea:
is
you
build
the
through
a
hierarchy,
and
then
you
essentially
do
repeated
instances
of
the
DRF
scheme,
but
what
we're
basically
saying
is
we
walk
down
the
tree
from
top
to
bottom
and
suppose
you
want
to
decide
on
which
role
I
get
the
next
resource
allocation.
There's
Russians
want
to
give
them
to
one
of
the
roles
which
one
should
we
give
them
to
remove.
C
So
we
basically
do
the
same
scheme
that
we
do
right
now,
which
it
is
in
a
flat
list
of
roles.
We
give
the
next
evaluation
with
you
the
role
that
is
farthest
below
its
fair
share,
so
we
just
repeat
that
process
for
each
level
that
free
starting
from
the
routan
going
downwards.
So
the
idea
here
is
that
inch
has
a
weight
of
one
and
becoming
as
a
weight
of
four.
So
that
means
n.
C
Should
twenty
percent
should
be
offered
by
twenty
percent
of
the
region's
Alfred
slightly
less
than
twenty
percent,
so
we
would
get
the
next
are
the
next
offer
within
an
inch?
We
have
a
wave,
let's
say,
of
9
to
14
analytics,
so
in
this
case,
analytics
actually
has
slightly
slightly
less
than
its.
Then
its
fair
share
front
end
has
is
above
it's
airtran,
Alexis
below
answer
shortly.
C
The
next
offer
first
in
and
then
to
NJ
and
analytics,
and
we
do
read
that
process
as
we
walk
further
further
down
the
tree
and
then
once
we
actually
end
up
making
an
allocation
or
resource
offer,
we'd
walk
back
up
the
tree
and
say
ok
when
we
not
allocated
analytics.
That
also
cannot
stand
on
occasion
to
see
so,
basically,
by
setting
the
weight
on
you
know,
one
operating
come
along
and
and
in
this
diagram,
set
the
weight
on
the
inverse
accounting
and
that
controls
that
high-level
Rios
allocation
decision.
C
C
Okay,
so
that's
the
basic
idea
behind
hierarchical,
fair
share
out
there.
We
also
support
or
out
more
want
to
support
hug.
So
the
idea
behind
quota
is
it's
basically
gank
egg
and
resource
allocation.
That
right
now
is
made
to
a
single
roll.
So
we
want
to
send
that
to
the
hierarchical
case.
So
the
idea
behind
her
quota
is
that
when
you
set
the
quota
on
a
child,
node
you're,
basically
dead
quotas,
sort
of
taken
from
that
child's
parents
quota.
C
So
we
look
at
this
example
here
and
she's,
given
a
coat
of
twenty
CPUs
accounting
is
given
a
quota
for
TCP.
That
means
that
the
whole
internal
organization,
however,
they
want
to
divide
up
those
resources,
get
20
guaranteed
schools.
Then
let's
say
we
have
a
greater
at
the
end
organization.
They
might
decide
that
ok,
inch
front
end
gets
four
of
those
guarantees.
C
It
is
in
NJ
analytics
gets
16
of
those
CDs,
so
they
can
then
set
the
quota
correspondingly
on
those
two
sub
rolls
to
make
that
guaranteed
to
extend
those
guaranteed
resources
further
down
the
tree,
and
that
would
generalize
onward
if
there
were
multiple
multiple
sub
rolls
under.
Let's
say
in
front
end
or
under
under
engine
olympics.
C
C
So
a
natural
question
is
what
happens
if,
in
this
example,
let's
say
we
didn't
have
in
front
of
waiting
at
you
know.
We
said
the
N
genetics
only
got
a
quarter
of
12
CPUs.
Does
that
mean
that
there's
for
unused
going
to
use
that
we
know
to
do
end
somewhere,
but
they
aren't
being
consumed
by
any
of
those
child
rules
basically
went
on
for
those
two
that
sub
train,
but
the
exact
semantics
we're
going
to
use
for
from
making
on
making
that
resource
offer
are
still.
We
still
want
to
exactly
match
those
out.
C
H
D
C
C
Ok,
so
we
also
want
to
extend
reservations
to
work
with
hierarchies,
so
the
idea
is
that
now,
when
you
make
a
reservation,
so
if
let's
say
there's
a
river,
you
know,
ang
has
reserved
resources,
then
that
reservation
effectively
reserves
resources
for
that
entire
subtree.
That's
rendered
it
n.
So
in
the
if
we
have
again
and
front-end
and
ang
analytics
or
you
make
reservation
to
end,
those
resources
would
be
eligible
to
offered
any
framework.
C
That's
registered
underneath
the
end
sub
tree
and
kind
of
work
for
the
week
that
we
want
to
support
here
is
a
notion
of
actually
kind
of
making
reservations
in
a
way
that
specializes
razor
cool,
so
we're
thinking
about
a
scenario
where
some
operator,
let's
say,
makes
one
resource
reservation
for
em.
You
might
say
that
okay,
the
the
analytics
team,
gets
these
particular
resources.
You
know
particular
matter
get
cpu
on
these
particular
host.
C
C
Well,
so
once
the
reservations
made
in
any
framework
with
ang
will
get
with
eligibly
all
of
those
results
once
the
framework
is
offer
those
resources.
If
they
want
to
kind
of
stake,
a
claim
other
resources,
they
can
reserve
them
from
the
higher-level
role,
which
is
n
JH
down
to
a
more
specific,
several,
so,
let's
say
in
front
end
resource
gets
offers
and
reserve
and
resources.
They
can
then
reserve
those
resources
to
move
them
from
being
reserved
by
n
to
being
reserved
by
n
front
end.
C
Then,
when
they're
done
using
them,
they
can
move
them
back,
unreserve
them
which
effectively
going
to
return
them
back
to
the
end
and
tremble.
It's
an
important
thing
to
observe
is
that
frameworks
in
the
end
sub
tree
first
of
all,
can't
unreserve
in
trouble
resources,
so
they
can.
What
resources
back
in
a
state
example
from
in
front
heading
back
up
to
inch,
but
they
can't
move
some
front
hinge
back
up
to
be
on
reserve.
C
They
also
can't
reserve
additional
resources,
so
they
can't
take
an
underserved
resource
and
you
know
I'm
sure
there
to
serve
to
ang
and
they
can't
use
sibling
resources.
So
they
can't
take
if
it
is
there's
a
framework,
that's
in
inch
front
end.
He
can't
take
some
resource.
That's
been
reserved
by
inch
back
end
and
move
it
into
in
front
of.
C
We
can't
mandate
or
we
don't
want
to
mandate
that
a
role
as
either
a
leaf
roll
or
an
internal
roll
and
can't
change
from
one
to
the
other.
So
in
particular,
if
you
think
about
everything
right
suppose
that
not
an
organization
was
using
those
and
they
only
have
a
role,
a
file
list
of
roles
and
they
want
to
gradually
move
from
our
files
ervil's
to
a
hierarchical.
Let's
say
they
want
to
place
the
end,
which
has
multiple
frameworks
with
ang
front-end
an
inch
back
in,
but
that
involves
updating
many
frameworks,
restarting
services.
C
C
So
what
do
we
do
this?
So
what
we
decided
to
do
is
to
basically
support
it.
What
we're
calling
virtual
leaf
leaf
nodes
and
it's
the
idea
that,
when
a
node
gets
promoted
from
a
lymph,
node,
2
p.m.
in
eternal
know,
so
in
other
words
winner,
when
what
was
a
leaf
node
when
there's
a
framework
that
registers
in
a
child
of
that
of
that
node,
so
it
transfers
that
leaf
node
in
do
a
kernel
mode.
We
basically
create
an
extra
leaf
now
so
to
represent
what
was
previously
allocated
to
the
only
rule.
C
So
it
might
actually
be
helpful
to
look
at
this
look
at
the
diagram
here.
That's
it
we're
moving
from
accounting
an
end
just
to
leaf
roles,
and
let's
say
that,
then
we
have
a
new
framework,
the
rivers
and
a
different
end.
So
that's
going
to
take
ang
and
turn
it
from
being
off
role
to
engine
an
internal
moon.
C
So
we
always
continue.
Making
allocations
to
leave
rolls
pretty
much
already
shows
lead
roles,
just
listen
to
create
this
week,
roll
if
necessary,
when,
when
a
new
child
leadership
under
what
was
previously
hope-
and
the
idea,
then,
is
the
next.
When
you
said
wait
on
in
your
setting,
wait
on
the
internal
node,
not
on
the
leaf
role.
So
we
basically
control
and
canal
image
is
going
to
compete
with
its
twin,
siblings
you're,
not
controlling
how
that
virtual
leaf
node.
C
So
this
virtual
leaves
will
always
have
the
default
awake
and
Louis
for
Kota.
So
explain,
but
I
mean
the
basic
idea
is
to
teach.
Chinese
is
committed
to
enable
advice
for
evolution
from
a
flat
list
of
roles
to
a
hierarchy
or
from
from
one
level
hierarchy
to
ignore
deeply
nested
marquee,
and
it
kind
of
give
you
deep
reasonable
behavior
as
you
can.
C
N
M
C
I
mean
it's
not
ideal,
I
think
like
in
one
sense
what
you're
doing
is
removing
from
a
configuration
where
yet
multiple
frameworks
in
n
JH,
so
you
already
kind
of
making
a
reservation
to
multiple
entities.
All
right
like
that,
you
couldn't
guarantee
you.
That
reservation
went
to
a
particular
framework,
so
you're
going
from
that
to
another
configuration
where
you
can't
guarantee.
The
reservation
goes
to
what
with
Winona
t
so.
M
M
C
I
M
Reserves
it
specializes
yeah.
If
there's,
if
there's
some
so
right
now,
we
just
want
to
basically
say
that
those
entire
nodes
are
reserved
for
system
marathon
and
you
can't
really
run
anything
else
on
there
effectively.
But
what
we're
trying
to
do
is
enable
you
know
any
SDK
framework
to
run
on
the
public
agents,
specifically
this
edge
LD
and
maybe
any
instances
of
this
edge
lb.
M
While
also
allowing
marathon
to
put
some
things
on
this,
the
public
agents
as
well,
these
reservations
are
static
or
dynamic.
Right
now,
there
static
using
dash
dash
default
role
actually,
which
reserves
the
all
the
resources
for
that
node
for
that
role,
buggy
home,
oh,
wait!
So
we're
with
this
and
help
me
get
its
resources,
the
edge
lb.
He
would
also
would
register
in
the
slave
public
/
Shelby
role,
and
it
would
get
offered
reservation.
M
These
statically
reserved
slave
public
resources
right
and
then
it
would
specialize
those
and
reserve
them
down
a
level
to
its
role
so
that,
when
it
tasks
die,
can
automatically
relaunch
them
on
the
same
reserve
resources
without
marathon
interrupting
but
marathon
by
default.
Well,
I
guess
we
haven't
figured
out
exactly
how
we
want
a
hierarchal
marathon
to
work.
M
Yeah
so
right
now
yeah
we
can.
We
can
take
this
offline
I,
don't
want
to
derail
meals,
presentation
too
much.
This
is
a
bigger
problem
that
we
need
to
solve
as
a
company
for
110,
but
the
mesas
community
isn't
directly
impacted
by,
but
you
know,
other
mesas
distros
might
have
similar
issues.
Okay,
if
used
static
and
flat
roles
in
weird
ways
like
we
have
sorry
carry
on.
C
C
So
current
status,
we
have
a
bunch
of
patched
up
that
do
the
basic
corn,
fritter
changes,
furniture,
allocation,
update
agents
and
do
authorization,
and
those
aren't
review
right
now
should
make
it
remains.
1.3
then
we're
looking
at
making
the
reservation
apply
to
a
subtree
that
change
we're
just
figuring
out
how
to
do
that.
Right
now
should
be
shouldn't
be
too
complicated,
hopefully
get
that
for
1.3
as
well,
and
then
quota
that
this
notion
of
delegating
that
unused
quota
over
whole
tree
that
we
might
defer
for
now,
but
will
probably
come
at
some
point.
C
So
as
of
right,
the
current
status
is
that
you
have
em
GPUs
end.
You
have
a
rule,
a
framework
and
roll
and
front-end
framework
to
get
I
offered
any
quoted
resources
that
in
front
end,
rule
itself
needs
to
have
quota.
So
you
can't
just
rely
on
the
fact
that
there's
a
hundred
CPU
an
inch
and
because
you're
under
m's
you'll
get
off
at
some
of
it.
Maybe
you
should
say:
okay.
Well,
there's
a
hood
see
keith
an
inch
guaranteed,
let's
guarantee
whatever
20
of
them
in
front
end.
C
F
M
Long
as
no
sibling
like
siblings,
that
have
more
specialized
quota
would
get
that
first
right.
So
any
leftovers
quota
from
the
parent,
like
if
I'm
back
end
and
there's
no
quota
for
me,
but
there's
quota,
French
food,
end
obvious
and
front
end
gets
that.
But
if
there's
leftover
ohta
for
edge,
then
it
should
be
available
to
any
of
the
inch
whatever.
F
F
M
Have
any
of
access
to
specialized
quota
I?
Think
I
mean
it's
not
even
specializing
quote
it's
just
setting
quota
on
the
child
and
as
long
as
that's
less
than
what
the
parent
has
that's
allowed,
and
now
you
have
quota
if
you're
authorized
to
set
that
and
that
I
think
applies.
I.
Think
it's
just
like
the
leftover
quota
that
is
not
like
the
parent
has
quota,
that's
not
assigned
to
any
trend.
We
can
do
anything.

But
probably
want
to
be
a
look
at
mikes
like
CPU
says
it's.
I
Got
a
mic
yeah,
I
think
that's
what
I
think
that's
Twitter
guys
that
wants
to
have
my
god,
cpu
affinity
that
I
think
they're
just
kiss
my
god,
you
don't
want
JDM
to
go
auditory
wider.
You
want
to
restrict
the
course,
since
the
ecfs
I
wanna
make
sure
there's
no
swelling
going
on
the
Congress
for
the
cpu
sets.
They
propose
something
on
the
meanest.
Looking
for
feedback
I'm,
just
wondering
like
that
any
should
we
set
up
something
on
to
get
that
school
discussion
going,
follow.
F
Just
can't
let
if
no
one
commissioner,
so
if
you
want
to
call
them
up
for
hookah
next
week,
I'll
stay
or
group,
we
can
prevent
it
personally.
Okay,
any
other
way
to
do
this
depends
on
who
gets
icons
to
share
that
stuff.
Yeah.
I
F
F
Live
I
presume
yeah.
You
just
awesome
to
come
over
on
thursday
step.
I'm
gonna
call
the
design
in
person
with
some
of
us
potentially
he's
a
good
start.
Is
here
yeah,
okay,.
I
I
M
On
but
and
in
the
past,
we've
we've
allowed
the
PMC
to
have
you
know
some
special
like
promoted
talks
like
where
it
ends
up
being
think
in
the
past,
we've
done
things
where
it's
like
one-third
from
one
track:
one-third
from
another
track
one-third
like
pmc
recommendations.
Maybe
one
third
is
too
much
in
this
case
right.
It's
very.
F
I
guess
the
previous
times
when
I
was
involved,
the
reason
may
be
hard
to
do
that
was
made
their
own
balance.
Finger
across
max
I
can
repair
some
crack
that
I'd
like
too
many
worlds
and
great
other
tracks
like
ever
an
office
or
something
didn't
have
enough
booty.
We
might
want
not
to
pick
the
bishop
offer
work.
M
O
M
I
The
final
six
yeah-
I
think
the
immediate
action
item
is
when
I
send
out
this
when
we
send
out
this,
like
a
vote.
Emails
that
reach
out
to
your
connections
are
a
marathon
on
this
item
is
so
simple
system
to
make
sure
they
both
non.
Those
talks
go
ahead,
so
we
feel
like
very
enough
permissions
yeah.
We
have
enough
submissions,
okay,
yeah.
I
think
I
skim
the
talks.
I
think,
like
may
I
mean
most
of
the
iphone
users,
just
because
there's
only
one
vendor
pretty
much
iphone.
I
My
sister
sonia
one
vendor
perish,
but
there's
a
lot
of
users:
actual
users,
okay,
which
is
good
I'm
sponsorship
when
sponsorship,
if
you
can
reach
out
to
a
network,
that
would
be
great.
So
we
don't
have
a
lot
of
sponsorship,
but
I'm
many
playing
like
minutes
foundation,
not
doing
a
good
job.
I
got
between
the
world
in
China,
because
there
another
conference
right
before
meters
car,
which
is
likely
nice
container
comp
Kyle
open
Stalin,
don't
have
any
like
la,
don't
have
a
lot
of
sponsorship
as
well.
