Subject: OO specification of BLAS

I am looking for information about attempts to define OO BLAS. I have found
a single technical report from 1994, where OO extensions were used with
BLAS to parallelize Neural Network computations. Please send info to me
directly and I will summarize the responses.

Subject: CFP: HybridNL at CPAIOR2011, Germany, May 2011

Call for Papers for the third workshop on
Hybrid Methods for Nonlinear Combinatorial Optimization Problems

To be held in conjunction with the International Conference CPAIOR 2011
Berlin, Germany, May 24, 2011.

This workshop aims at bringing together scholars and practitioners from the
Mixed Integer Nonlinear Programming (MINLP) and the Constraint Programming =
community to share their thoughts on the theory and implementation of solve=
for MINLP and CP problems. This is the third edition that follows two works=
held at CPAIOR 2009 in Pittsburgh, PA and at CPAIOR 2010 in Bologna, Italy.
This workshop is motivated by the recent development of new solvers and
exciting new results in MINLP and CP.

The organizing committee invites submissions of a short abstract (about
4000 characters) outlining original work, reporting preliminary results,
describing an open problem, or proposing ideas for bringing new
computational methods into the field. We emphasize that the scope of the
workshop is to describe new and pioneering work in MINLP and/or CP, which
therefore does not necessarily have to be completed work.

Important Dates
March 25, 2011: Abstract submission due
April 10, 2011: Notification of acceptance
May 24, 2011: Workshop date

Abstracts can be submitted by email to Pietro Belotti at pbelott@clemson.ed=
