Talk Title: Multiprocessor Architectures for Speculat

ive Multithreading

Talk Abstract:
One of the biggest challenges f

acing computer architecture
today is the design of parallel architecture

s that make it
easy for programmers to write parallel codes. One of the<

br>architectural technologies that is showing great versatility
and pote

ntial in this direction is Speculative Multithreading.
In this talk I w

ill discuss the many uses of this technology
in multiprocessors and its
remarkable potential for perform-
ance and programmability (Thread-Leve

l Speculation
Speculative Synchronization Transactional Memory and
BulkSC) hardware reliability (Paceline) and software
dependability (
