Subject: SAWdoubler 1.0 released, counting self-avoiding walks

We are happy to announce the release of SAWdoubler version 1.0, a
software package for counting the total number of Self-Avoiding Walks
on a regular lattice by the length-doubling method.

The aim of the package is to enable counting self-avoiding walks on a
variety of lattices, and to stimulate research into this topic.
Please feel free to explore the possibilities of modifying this

The package includes an example lattice, the 3D cubic lattice for
which we recently reached the record length of 36 steps, computing
Z(36)= 2,941,370,856,334,701,726,560,670 on the Huygens supercompouter
at SARA in Amsterdam.

The software and the accompanying papers can be downloaded from

The package is written in C and is released under the GNU LGPL

Subject: Explicit parallel peer Fortran95 code for ODEs avaliable

EPPEER is a Fortran95/OpenMP implementation of explicit parallel
two-step peer methods for the solution of ODEs on current multicore
PCs. Features of the code are:
* choice between 7 methods with orders 3..9
* methods may use 2..8 parallel cores through OpenMP
* no parallelization of ODE callrequiredby user
* automatic stepsize control with absolute and relative tolerances
* continous output with full order of convergence

Peer methods are multi-stage two-step methods where all stages have
the same accuracy, introduced by the authors in SINUM 42 (2004).

The EPPEER code and documentation are available at and

Comments and suggestions are welcome.

Subject: Hilarious scientific programming vidoes

Hello NA Digest,

The NA community is too small for these humorous videos about
object-oriented scientific programming to go viral, so I thought I
would pass along the links:

Do not watch if you are upset by movies about Hitler! The videos may
remind you of some groups you've worked in. It has become a tradition
to subtitle over the famous rant scene by Bruno Ganz in Downfall (Der
Untergang). These videos evidently were made by someone in FEniCS.

Subject: Comp Sci Postdoc Fellow, Lawrence Berkeley NL

We’re Hiring a Computational Science Postdoctoral Fellow at Lawrence
Berkeley National Laboratory! Req. #75040

The Center for Computational Sciences and Engineering has openings for
two postdoctoral researchers to work at the interface between the
development of combustion methodology for exascale architectures and
computer science research aimed at developing the software stack
needed to support exascale computing.

More specifically, the postdoctoral researchers will work on the
development of a programming environment for fluid dynamics and
combustion simulation codes. These simulation codes will enable the
design of future advanced combustion devices such as diesel engines
and low-swirl combustion devices for efficient heating and energy
production. These positions would be affiliated with the Center for
Exascale Simulation of Combustion in Turbulence (ExaCT) and would
interact closely with computer science teams associated with the DOE
X-Stack program. The goal of ExaCT is to perform multi-disciplinary
research required to iteratively co-design all aspects of combustion
simulation including math algorithms for partial differential
equations, programming models, scientific data management and
analytics for *in situ* uncertainty quantification and topological
analysis, and architectural simulation to explore hardware tradeoffs
with proxy applications that represent the anticipated workload on
future exascale supercomputing systems. For more information about:
ExaCT see; the DOE X-stack program see; and, the Center for Computational Sciences and
