CADO workshop on integer factorization
INRIA Nancy-Grand Est (INRIA Lorraine), Villers-lès-Nancy, France
October 7 – 9, 2008

http://cado.gforge.inria.fr/workshop/

The CADO workshop on integer factorization will take place at INRIA
Lorraine (LORIA), Villers-lès-Nancy, France, from October 7th to 9th,
2008.

The topic of the workshop is integer factorization and in particular the
Number Field Sieve algorithm and its implementations. The CADO workshop
takes place just before Sage Days 10, scheduled just in the same place
from Oct. 10th to 15th.

Confirmed speakers:

* Kazumaro Aoki, NTT ;
* Daniel J. Bernstein, University of Illinois at Chicago ;
* William B. Hart, University of Warwick ;
* Thorsten Kleinjung, EPFL-LACAL ;
* Reynald Lercier, CELAR & Université de Rennes 1 ;
* Peter L. Montgomery, Microsoft Research ;
* (list to be completed)

Besides invited talks, some contributed talks on the topics of the
workshop may be included depending on submissions. Participants willing
to present work on integer factorizations are kindly requested to contact
the organizers as soon as possible. Note that no proceedings are planned
for the workshop.

Registration

The registration is not open yet. A low registration fee will be asked in
order to cover for lunches and coffee breaks.

The CADO project is an initiative from the CACAO project-team at INRIA
Lorraine, the TANC project-team at INRIA Saclay, and the number theory
group at IECN. CADO and the CADO workshop are funded by ANR, the French
research agency.

I think that I've been insulted.

Why? Because the initial apologies apply to you, in that you've now seen several postings?

Otherwise, I see nothing untoward in the announcement.

There is nothing wrong in the announcement.....

I see a number of people who were invited to give talks who have
never implemented NFS, factored a number, or published a paper on
NFS.

Yet I was not invited........I feel slighted.

In that case, offer to give a talk. The announcment says:

I could give a talk. I have some (new) results on optimal selection of
the *size* of the sieve region for the lattice sieve. The results are
similar to those of my recent paper on line sieve. --> One always wants
to sieve in regions where the probability of success is highest, and for
the lattice sieve this means that the regions should decrease in size
as the special q increase. I am working on a more precise quantification
of this statement.

But I wasn't invited. And right or wrong I do feel slighted.

I'm curious as to a bound on the number in question. If I were
able to attend, I'd certainly be interested to hear whatever
Lercier has to say. I don't know anything about Hart, but I
presume that's my fault, rather than the organizers. Everyone
else has certainly factored one or more interesting numbers
(at the time, at least). I count four of six that have written
(parts) of nfs code, and perhaps Lercier as well on CADO-nfs?
Likewise, four of six (that I know of) on having published a paper
on nfs. You haven't mentioned interest in contributing to the
cado project, which would also seem to be a relevant consideration.
Sounds to me like one or two speakers not one-of-the-usual-suspects,
which isn't anything to be insulted about. Another point on speaker
selection, looks like two were part of the kilobit snfs project, a large
fraction of the people that have actually used the distributed parallel
Wiedermann. Bernstein has had more than anyone's fair share of
good thoughts on computation ("circuits", for example, as well as the
maspar nfs, before many other people had nfs's). I'm fairly sure that
you're not disputing Peter's inclusion, for many reasons, but especially
for current thoughts on 768-bit nfs. Seems mostly plausible to me
(not that I'd count, by your standards). Peace, Bruce

Bill is much more involved with SAGE than with factoring. Last I heard he was doing a lot of work on multithreaded (QS) factoring, or more generally multithreaded computational number theory

I'm tempted to go along, though it's seven hours each way by train and annoyingly mid-week. Presumably akruppa will be there; anyone else from the forum?

I'm thinking about it, but I just started a new job, leave is scarce, and I'm not sure what I could talk about, so probably not me.
