APS DFD 2010 Talk Slides

As promised, sort of, here are the slides from my APS DFD 2010 talk:

A WENO-Based Code for Investigating RANS Model Closures for Multicomponent Hydrodynamic Instabilities

Go listen to The Mikie Show

An old acquaintance has been running an amazing radio show called The Mikie Show for some time now. If you get the chance, take a listen. Think Mister Rogers on the radio if Mister Rogers happened to be a sound designer/musician with a groanful sense of humor.

Recently my friend Billy, an arborist, was in episode 25. Billy's fun. When asked "Does hugging a tree really help it?" Billy didn't miss a beat and replied "It depends what you're going to do next."

Imminent (but probably dizzy) bundle o' joy

My wife amazes me most days. Today especially.

The bump's our son. He should be arriving in the next three to seven weeks.

GNU Parallel

I discovered GNU Parallel today.  Phenomenal.  Especially for simple post processing on multicore systems.  Watch the video-- it is quite good.  Here are three sample commands taken from a bash script where $1 is set to be a particular prefix...

parallel --eta -j +0 ./gnuplot.sh -g -F {} $1.r???? ::: `seq 1 8`

Runs a custom gnuplot-based shell script eight times against a file glob.  Each time provide a different argument in the  set {1,2,...,7,8}.  The results are stored as $1.f1.gif, $1.f2.gif, etc.

ls -1 $1.r???? | parallel --eta -j +0 'montage -geometry 1280x960 -tile 4x2 {}.f?.gif {}.miff'

Create a tiled montage of the eight output files mentioned above and store the result in $1.miff.

ls -1 $1.r???? | parallel --eta -j +0 'convert {}.miff {}.gif'

Convert the resulting MIFFs into GIFs.

I win.  On my system, 8 - 0.
