PROGRAMMING MULTICORES:
DO APPLICATIONS PROGRAMMERS
NEED TO WRITE EXPLICITLY
PARALLEL PROGRAMS?

IN THIS PANEL DISCUSSION FROM THE 2009 WORKSHOP ON COMPUTER ARCHITECTURE
RESEARCH DIRECTIONS, DAVID AUGUST AND KESHAV PINGALI DEBATE WHETHER EXPLICITLY
PARALLEL PROGRAMMING IS A NECESSARY EVIL FOR APPLICATIONS PROGRAMMERS,
ASSESS THE CURRENT STATE OF PARALLEL PROGRAMMING MODELS, AND DISCUSS
POSSIBLE ROUTES TOWARD FINDING THE PROGRAMMING MODEL FOR THE MULTICORE ERA.
Moderator's introduction: Arvind
Do applications programmers need to write
explicitly parallel programs? Most people be-
lieve that the current method of parallel pro-
gramming is impeding the exploitation of
multicores. In other words, the number of
cores in a microprocessor is likely to track
Moore's law in the near future, but the pro-
gramming of multicores might remain the
