Abstract:
As
the
benefits
from
Moore’s
Law
are
approaching
an
end,
new
technologies
are
being
proposed
and
developed
to
satisfy
the
ever-growing
demand
for
performance.
One
of
these
technologies
is
persistent
memory,
such
as
Intel’s
recently-released
Optane
DC
Persistent
Memory.
It
is
a
unification
of
memory
and
storage,
satisfying
the
demand
for
better
performance
and
higher
memory
capacity.
However,
the
adaption
of
this
new
memory
technology
would
require
a
redesign
of
the
system
stack,
where
both
software
and
hardware
aspects
are
critical
to
the
adaption
of
persistent
memory.
In
this
talk,
I
will
focus
on
both
the
software
and
hardware
aspects
of
system
support
for
persistent
memory.
On
the
software
side,
I
will
present
how
my
work
ensures
the
correctness
of
software
systems
designed
for
this
new
memory
technology.
On
the
hardware
side,
I
will
present
my
work
on
an
efficient
and
secured
persistent
memory
hardware
system.
Finally,
I
will
describe
my
future
research
on
more
broad
applications
for
persistent
memory,
as
well
as
a
longer-term
research
plan
on
providing
system
support
for
other
emerging
technologies.
Biography:
Sihang
Liu
is
a
Ph.D.
candidate
in
the
Computer
Science
Department
at
the
University
of
Virginia.
His
research
interests
lie
in
computer
systems
and
architecture.
During
his
Ph.D.,
he
has
focused
on
building
system
support
for
a
new
memory
technology,
persistent
memory,
spanning
both
the
software
and
hardware
stack
for
this
memory
technology.
His
research
has
been
published
at
major
systems
conferences,
such
as
ASPLOS,
ISCA,
and
HPCA.
From
these
research
projects,
he
has
produced
five
open-sourced
artifacts.
His
work
has
been
recognized
by
the
2019
MICRO
Top
Picks--Honorable
Mention,
the
final
list
of
NVMW
2019
memorable
paper
award,
and
a
Google
Ph.D.
fellowship
award.
As
for
professional
service,
he
has
served
as
a
paper
reviewer
for
top
conferences
and
journals,
such
as
ISCA,
ASPLOS,
TACO,
ToS,
and
TPDS,
and
an
artifact
reviewer
for
multiple
systems
conferences,
such
as
OSDI,
ASPLOS,
and
EuroSys.
Additionally,
he
currently
serves
as
a
co-chair
of
a
Computer
Architecture
Long-term
Mentoring
program
(CALM)
and
a
board
member
of
the
Computer
Architecture
Student
Association
(CASA),
to
support
junior
researchers
and
those
from
underrepresented
backgrounds.
