Blog: HPC examples with Python
AstroPython reader Moritz writes:
While looking for good way to define a banded matrix in Python I stumbled on the following tutorial:
HPC Techreport: A brief introduction to Python
After the standard introduction to basic Python concepts, I quite like the way different HPC solutions are built up in the end (numpy, scipy, weave, Cython) to lead to one example implemented with very different approaches.
In the end ...

Blog: Python in HPC
HPCWire's interview with Argonne National Lab's William Scullin, on the adoption of Python in high performance computing.
"While there has always been an emphasis on reducing the time it takes to perform a computation, Python has truly shined in improving scientific computing by taking the work out of programming and reducing the time to solution.".
