2. APU:
ACCELERATED
PROCESSING
UNIT
! The
APU
has
arrived
and
it
is
a
great
advance
over
previous
plaKorms
! Combines
scalar
processing
on
CPU,
parallel
processing
on
GPU,
co-­‐processors
and
high
bandwidth
access
to
memory
! Higher

11. CPU
TIME
BASED
PROFILING
! Usage
‒ Is
used
for
finding
program
level/algorithmic/data
structure
related
performance
issues
! Profiling
Method
‒ The
user
defines
a
Vme
interval
(default
is
1
msec)
‒ On
every
Vme
interval,
for
each
thread,
the
profiler
logs
the
instrucVon
pointer
‒ Call-­‐stack
logging
is
opVonal
(very
useful)

EVENT
BASED
PROFILING
! Usage
‒ Is
used
for
locaVng
CPU
micro-­‐architectural
related
performance
issues
! Profiling
Method
‒ The
user
selects
an
event
(example:
cache
misses)
‒ The
user
defines
event
count
(example:
5000)
‒ A
counter
counts
the
event
occurrences
(cache
misses)
‒ When
the
counter
reaches
the
event
count,
the
profiler
logs
the
instrucVon
pointer
‒ Call-­‐stack
logging
is
opVonal
