RACES 2012

Title:       Relaxing Synchronization for Multicore and Manycore Scalability, SPLASH'12 Workshop
Deadline:    2012-08-06
Webpage:     http://soft.vub.ac.be/races/
Conference:  October 21, 2012
Contact:     [log in to unmask]
Location:    Tucson, Arizona, USA
Synopsis:

Massively-parallel systems are coming. Conventional wisdom has been to
utilize this parallelism by reducing synchronization to the minimum
required to preserve determinism - in particular, by eliminating data
races. However, Amdahl's law implies that on highly-parallel systems
even a small amount of synchronization that introduces serialization
will limit scaling. Thus, we are forced to confront the trade-off
between synchronization and the ability of an implementation to scale
performance with the number of processors: synchronization inherently
limits parallelism. This workshop focuses on harnessing parallelism by
limiting synchronization, even to the point where programs will
compute inconsistent or approximate rather than exact answers.

  Title:  THE 2012 EDSGER W. DIJKSTRA PRIZE IN DISTRIBUTED COMPUTING

  Summary:   The ACM-EATCS Edsger W. Dijkstra Prize in Distributed
Computing is awarded to outstanding papers on the principles of distributed
computing, whose significance and impact on the theory or practice of
distributed computing have been evident for at least ten years. The
prize is sponsored jointly by the ACM Symposium on Principles of
Distributed Computing (PODC) and the EATCS Symposium on Distributed
Computing (DISC).

The 2012 Prize Committee, composed of Marcos K. Aguilera (chair),
Dahlia Malkhi, Keith Marzullo, Alessandro Panconesi, Andrzej Pelc,
and Roger Wattenhofer has selected

  Maurice Herlihy, J. Eliot B. Moss, Nir Shavit, and Dan Touitou

to receive the 2012 Edsger W. Dijkstra Prize in Distributed Computing
for the following two outstanding papers:

  Maurice Herlihy and J. Eliot B. Moss.
  Transactional Memory: Architectural Support for Lock-Free Data Structures.
  20th Annual International Symposium on Computer Architecture,
  pages 289-300, May 1993.

  Nir Shavit and Dan Touitou.
  Software Transactional Memory.
  Distributed Computing 10(2):99-116, February 1997.
  (An earlier version appearing in the 14th ACM Symposium on
  Principles of Distributed Computing, pages 204-213, August 1995.)

These papers established the abstraction of Transactional Memory,
which has fundamentally changed parallel computing both in its
theoretical foundations and in its practice.

As with many influential papers, the work by Herlihy and Moss presents
a beguilingly simple idea: extend load-linked and store-conditional to
allow a processor to update a collection of locations atomically. This
idea arose from deep insights:

- By allowing the creator of a concurrent data structure to focus on
  what should be atomic rather than how it should be made atomic,
  transactional memory significantly raises the level of abstraction
  for parallel programs, thereby eliminating much of the complexity of
  lock-free programming.

- Because actual dynamic conflicts among operations are rare in
  well-written programs, a speculative implementation of atomicity can
  enjoy a significant performance advantage over more conservative
  approaches.

- Given that cache coherence protocols already track conflicts among
  processors, multi-location atomic update can be realized in hardware
  by introducing a small "transactional cache" and by making simple
  modifications to standard cache coherence protocols.

This last insight notwithstanding, Herlihy and Moss's proposal proved
too ambitious for the hardware of the day, and their work was largely
ignored within the architecture community for most of the following
decade. Within the theory community, however, it inspired multiple
explorations of the limits of software emulation, most notably the
Software Transactional Memory work of Shavit and Touitou.

Building on earlier universal non-blocking constructions, Shavit and
Touitou showed how to achieve lock freedom without the need for costly
recursive helping, and thus provide effective non-blocking multi-word
operations purely in software. It was the first work to demonstrate
that software transactions could, under the right circumstances,
outperform conservative locking.

In terms of fostering research, transactional memory has become a
truly transformative idea. For example, two years ago, the second
edition of the monograph by Harris, Larus, and Rajwar on Transactional
Memory listed over 350 papers in the field. Google Scholar reports
almost 1400 citations to Herlihy and Moss, and almost 1000 to Shavit
and Touitou. The annual TRANSACT workshop, sponsored by ACM SIGPLAN,
is now planning its eighth incarnation. In terms of practice, software
architects have developed dozens of runtime implementations, both
blocking and non-blocking, of dazzling algorithmic variety. At least
four major compilers, including gcc, now support transactional memory
in C++. Hardware implementations have been developed by Azul, Sun
(Oracle), AMD (on paper), IBM, and Intel.  The IBM and Intel
implementations, in particular, ensure that hardware support is here
to stay.

These two papers started the distributed computing research community
along the path towards the design of general multi-word transactions;
ones that in the future will most likely be based on a combination of
hardware, software, and language techniques. Transactional memory
serves as an outstanding example of how the distributed computing
community has influenced the world.
