TITLE:
The Impact of Thread Size and Selection on the Performance of
Thread-Level Speculation
ABSTRACT:
Thread Level Speculation gives the compiler the ability to parallelize
code aggressively: threads can be created with possible dependences between
them. This gives the TLS compiler a degree of freedom which previous parallelizing
compilers did not have, but the compiler still has to decide where to
apply TLS. In this talk I discuss the issues involved in deciding where
to apply TLS to existing programs, and present results from a study of
applying TLS to a large collection of loops.
BIO:
Chris Colohan is a sixth year PhD student in the CS program, attempting
to finish his degree. As far as his advisor is concerned, Chris spends
all of his waking hours chained to his desk writing compilers, crafting
simulators, preparing talks, studying benchmarks, and fine tuning his
mind. In case you were wondering, Chris would like to receive a thesis
for his birthday.
