Talk Title: Post-Link Technology and Its Significance to the Marketplace

Talk Abstract:
Post-link technology is usually known as the soft

ware
tooling for applying transformations directly on the binary
ex

ecutable files. These tools include feedback-directed
binary-level opt

imizers binary instrumentation or binary
probing for monitoring or sim

ulation purposes and binary-
level performance analyzers. This is a co

mplex and
important technology that relies on accurate and
comprehe

nsive disassembly of the given executable file.
Post-link technology h

as now become a key player in the
future success of the new emerging mu

lti-core platforms
as the research and experience gathered on post-lin

k code
is now needed in order to be able to applyhigh-performance
o

ptimizations directly on the image of the program at run-time.
Today

companies such as IBM use post-link tools in their daily
builds for per

formance analysis design verification and its
optimization processes.
In this talk I will go over some of the
existing post-link tools used
in IBM and their variety of usage
along with an overview of the key c

hallenges that this technology
is facing.

Speaker Bio:
Gad Ha

ber earned his PhD in Mathematics and Computer Science
at Haifa Univers

ity in Israel after completing his undergraduate
studies in Jerusalem a

t Hebrew University. Since 1993 he has
been a senior architect special

izing in post-link tools for performance
analysis optimizations and bi

nary instrumentation at IBM''s research
facility in Haifa. He also lec

tures on Java at Haifa University.
