Fair enough.

I just defer all of the actual blocking to native semaphores and rely on the
fact that the synchronization algorithm itself provides certain "guarantees"
when a thread returns from a semaphore wait. A thread that returns from a
native wait does not need to read any state because it already "knows" its
state.
Also, keep in mind that the wait operations will only be called one single
time per-slowpath because there is no looping. So, that "can" be more
"efficient" because if you have to loop around you may end up calling a
native wait operation more than one time.

Indeed! :^)

Yeah. The fairness is just sort of an inherent aspect of the algorithm.

PURPOSE / HISTORY:
CGVR'10 Conference is being held jointly (same location and dates)
with a number of other research conferences (WORLDCOMP).
WORLDCOMP is the largest annual gathering of researchers in
computer
science, computer engineering and applied computing. We anticipate
to have 2,000 or more attendees from over 85 countries
participating
at WORLDCOMP Congress. A number of individual research tracks of
the Congress have been held for many years; for example, PDPTA has
been held annually since 1995 (PDPTA'10 is the 16th annual
conference); ERSA has been held annually since 2001 (ERSA'10 is the
10th annual conference); ICAI has been held annually since 1999
(ICAI'10 is the 12th annual conference); CGVR has been held
annually since 1997 (CGVR'10 is the 14th annual conference;
originally it was offered as CISST). Other tracks of WORLDCOMP
Congress have similar records.
The motivation behind this federated congress is to assemble
a spectrum of affiliated research conferences into a coordinated
research meeting held in a common place at a common time. The
main goal is to provide a forum for exchange of ideas in a
number of research areas that interact. The model used to form
CGVR facilitates communication among researchers from all
over the world in different fields of computer science,
computer engineering, applied computing, and computational
biology. Both inward research (core areas) and outward research
(multi-disciplinary, inter-disciplinary, and applications) will
be covered during the conference. CGVR makes concerted effort
to reach out to participants affiliated with diverse entities
(such as: universities, institutions, corporations, government
agencies, and research centers/labs) from all over the world.
CGVR'10 will be composed of research presentations, keynote
lectures, invited presentations, tutorials, panel discussions,
and poster presentations. In recent past, keynote/tutorial/panel
speakers have included (as part of the federated event):
Prof. David A. Patterson (pioneer/computer architecture, U. of
California, Berkeley), Dr. K. Eric Drexler (known as Father of
Nanotechnology), Prof. John H. Holland (known as Father of
Genetic Algorithms; U. of Michigan), Prof. Ian Foster (known as
Father of Grid Computing; U. of Chicago & ANL), Prof. Ruzena
Bajcsy (pioneer/VR, U. of California, Berkeley), Prof. Barry
Vercoe (Founding member of MIT Media Lab, MIT), Dr. Jim Gettys
(known as X-man, developer of X Window System, xhost; OLPC),
Prof. John Koza (known as Father of Genetic Programming,
Stanford U.), Prof. Brian D. Athey (NIH Program Director, U. of
Michigan), Prof. Viktor K. Prasanna (pioneer, U. of Southern
California), Dr. Jose L. Munoz (NSF Program Director and
Consultant), Prof. Jun Liu (Broad Institute of MIT & Harvard U.),
Anousheh Ansari (CEO, Prodea Systems & first female private
space explorer), and many other distinguished speakers. To get

SUBMISSION OF PAPERS, PUBLICATION, INDEXING INFORMATION:
Prospective authors are invited to submit their papers by
uploading them to the evaluation web site at:
http://worldcomp.cviog.uga.edu/
Submissions must be uploaded by March 1, 2010 and they must
be in either MS doc (but not docx) or pdf formats (about 5
to 7 pages - single space, font size of 10 to 12). All
reasonable typesetting formats are acceptable (later, the
authors of accepted papers will be asked to follow a
particular typesetting format to prepare their final papers.)
The length of the Camera-Ready papers (if accepted) will be
limited to 7 (IEEE style) pages. Papers must not have been
previously published or currently submitted for publication
elsewhere. The first page of the draft paper should include:
title of the paper, name, affiliation, postal address, and
email address for each author. The first page should also
identify the name of the Contact Author and a maximum of 5
topical keywords that would best represent the content of
the paper. Finally, the name of the conference (ie. CGVR)
must be stated on the first page.
Full papers will be evaluated for originality, significance,
clarity, impact, and soundness. Each paper will be refereed
by two experts in the field who are independent of the
conference program committee. The referees' evaluations will
then be reviewed by one member of the program committee who
will recommend a decision to the chair of the track that
the paper has been submitted to. The chair will make the
final decision. Lastly, the final papers will be reviewed
by one member of the program committee.
All accepted papers will be published in the respective
conference proceedings (in both, printed book form as well as
online). The proceedings will be indexed in Inspec / IET /
The Institute for Engineering and Technology, DBLP / Computer
Science Bibliography, and others.) The printed proceedings
will be available for distribution on site at the conference.
In addition to the publication of the proceedings, selected
authors will be invited to submit extended versions of their
papers for publication in a number of research books being
proposed/contracted with various publishers (such as, Springer,
Elsevier, IOS, ...) - these books would be composed after the
conference. Also, many chairs of sessions and workshops will
be forming journal special issues to be published after the
conference.
IMPORTANT DATES:
March 1, 2010: Submission of papers (about 5 to 7 pages)
March 25, 2010: Notification of acceptance
April 22, 2010: Final papers + Copyright + Registration
July 12-15, 2010: The 2010 International Conference on Computer
Graphics and Virtual Reality (CGVR'10)
URL: http://www.world-academy-of-science.org
MEMBERS OF PROGRAM AND ORGANIZING COMMITTEES:
The Program Committee includes members of chapters of World
Academy of Science (chapters: supercomputing; scientific
computing; AI; imaging science; databases; simulation;
software eng.; embedded systems; internet & web technologies;
communications; computer security; & bioinformatics.) The
Program Committee for CGVR'10 conference is currently
being formed. Many who have already joined the committees
of individual tracks are renowned leaders, scholars,
researchers, scientists and practitioners of the highest
ranks; many are directors of research labs., fellows of
various societies, heads/chairs of departments, program
directors of research funding agencies, deans and provosts.
You can view the list of program committee of the last two
offerings of CGVR at:
http://www.worldacademyofscience.org/worldcomp08/ws/conferences/cgvr08/committee
http://www.worldacademyofscience.org/worldcomp09/ws/conferences/cgvr09/committee
Program Committee members are expected to have established
a strong and documented research track record. Those
interested in joining the Program Committee should email
H. R. Arabnia (hra@cs.uga.edu) the following information for
consideration/evaluation: Name, affiliation and position,
complete mailing address, email address, a one-page biography
that includes research expertise and the name of the conference
offering to help with (ie, CGVR).
LOCATION OF CONFERENCE:
CGVR'10 will be held at Monte Carlo Resort, Las Vegas,
Nevada, USA (with any overflows at other near-by hotels).
This is a mega hotel with excellent conference facilities and
over 3,000 rooms. It is minutes from the airport with 24-hour
shuttle service to and from the airport. This hotel has many
recreational attractions, including: waterfalls, spa, pools,
sunning decks, Easy River, wave pool, nightly shows, many
restaurants, ... The hotel is adjacent to CityCenter
( http://en.wikipedia.org/wiki/CityCenter ) which is the
largest private development in the United States' history
(costing over $11 Billion); this offers access to additional
recreational and entertainment attractions. The negotiated
room rate for conference attendees is very reasonable.
