Subject: How fine is floating-point arithmetic?

How fine is the IEEE floating-point number system?
Here is one way to see the answer.

According to molecular physics, there are approximately
3e8 molecules per meter in a gas at atmospheric
conditions -- essentially the cube root of Avogadro's
number. The circumference of the earth is 4e7 meters,
so in a circle around the earth, there are around
10^16 molecules.

In IEEE double precision arithmetic, there are 2^52
numbers between 1 and 2, which is also about 10^16.

So if we put a giant circle around the earth with a
distance coordinate ranging from 1 to 2, the spacing
of the floating-point numbers along the circle will
be about the same as the spacing of the air molecules.

Subject: Matrices Speak in Friendly Tones

Halloween this week is followed rapidly by several other holidays between
now and year 2008.

In the spirit of Gene Golub's suggestion to cover topics of interest to
the readership that mix the strictly technical with the non-technical, a
holiday custom is expressed below in terms of the rules observed by your
friendly family matrix.

Here is an expression of good will through this season from one who is
submitting at this end to you who are out there reading at your end: For
you as for your matrix,


o Your friends and family be Associative

o Your work be Distributive

o And may you not Commute.

Subject: OpenMP 3.0 Draft Specification Released for Public Comment

OpenMP 3.0 Draft Specification Released for Public Comment

21 October 2007

The OpenMP ARB is pleased to announce the release of a draft of Version
3.0 of the OpenMP specification for public comment. This is the first
update to the OpenMP specification since 2005.

This release adds several new features to the OpenMP specification,

* Tasking: move beyond loops with generalized tasks and support
complex and dynamic control flows.

* Loop collapse: combine nested loops automatically to expose more

* Enhanced loop schedules: Support aggressive compiler
optimizations of loop schedules and give programmers better
runtime control over the kind of schedule used.

* Nested parallelism support: better definition of and control
over nested parallel regions, and new API routines to determine
nesting structure

Larry Meadows, CEO of the OpenMP organization, states: "The creation of
OpenMP 3.0 has taken very hard work by a number of people over more than
two years. The introduction of a unified tasking model, allowing
creation and execution of unstructured work, is a great step forward for
OpenMP. It should allow the use of OpenMP on whole new classes of
computing problems."

The draft specification is available in PDF format from the
Specifications section of the OpenMP ARB website:

(Direct link:

Mark Bull has led the effort to expand the applicability of OpenMP while
improving it for its current uses as the Chair of the OpenMP Language
Committee. He states: "The OpenMP language committee has done a fine job
in producing this latest version of OpenMP. It has been difficult to
resolve some tricky details and understand how tasks should propagate
across the language. But I think we have come up with solid solutions,
and the team should be proud of their accomplishment."

The ARB warmly welcomes any comments, corrections and suggestions you
have for Version 3.0. For Version 3.0, we are soliciting comments
through an on-line forum, located at The
forum is entitled Draft 3.0 Public Comment. You can also send email to if you would rather not use the forum. It is most
helpful if you can refer to the page number and line number where

Subject: KKTDirect 0.3: a direct solver for saddle-point matrices

I'm pleased to offer KKTDirect, a public domain package for the
direct solution of a large class of saddle-point or "KKT" matrices
(symmetric indefinite problems arising in many application areas).

It is based on a new ordering constraint that is sufficient to
guarantee existence of the LDL^T factorization, and allows the solver
to predict in advance the signs of D, allowing near-Cholesky-like

The package includes a prototype minimum degree algorithm
incorporating the constraint, a post-processing algorithm for
arbitrary orderings, pointwise up-looking and supernodal left-looking
factorization/solution codes that retain the efficiency of modern
Cholesky codes for SPD matrices, and a simple MATLAB MEX interface.

The code along with a report describing the underlying theory and
numerical experiments are available from

This release is only alpha quality - in particular, some routines
require further optimization, and out-of-memory errors are not
handled gracefully - so use at your own risk.

Subject: Revision 5.0.3 of Scotch is out

We announce the release, as libre/free software, of revision 5.0.3 of the
SCOTCH and PT-SCOTCH software package and library for graph and
mesh/hypergraph partitioning, static mapping, and sequential and parallel
sparse matrix block ordering.

Revision 5.0.3 provides a ParMeTiS compatibility library which allows users
who are using the parallel graph ordering capabilities of ParMeTiS to try
PT-Scotch without having to modify their source code. Since PT-Scotch can
run on numbers of processors which are not powers of two, there are slight
changes in the values returned by the PT-Scotch implementation of the
ParMETIS_V3_NodeND() routine over the original implementation.

SCOTCH is a project carried out at the Laboratoire Bordelais de Recherche en
Informatique (LaBRI) of the Universite Bordeaux I.
It is part of project ScAlApplix of INRIA Futurs. Its goal is to apply graph
theory, with a ``divide and conquer'' approach, to scientific computing
problems such as graph partitioning, static mapping, and sparse matrix

Scotch can be freely downloaded, under the terms of the CeCILL-C license.
To ease the development, diffusion, and circulation of information regarding
the SCOTCH project, most of its resources are now hosted on the InriaGforge
platform provided by INRIA. Please refer to the SCOTCH web page at :

for more information. People interested in the SCOTCH project are welcome to

Haiku is a form of non-rhyming Japanese poetry whose form in
English often consists of 3 lines of 5, 7, and 5 syllables, typically with a
pause in the middle to split a comparison or contrast. Classical Haiku
invokes Nature or one of the Seasons. So for this week's NA Digest,
