It is not so much about parallel programming experience but about
scientific software development career path. Quite often parallel
skills are needed anyway. A former colleague and a good friend of mine
explains it quite nicely here:


Yes, we had a number of long debates about the topic. There is a
feeling that scientific software is much better funded in the US than
elsewhere and respectively software developers are a more valuable
asset there (hence the brain drain). But then again they spend a lot
more on the hardware too. The software spend is still insufficient if
you listen to Jack Dongarra and others.
