Today we have a guest post by Ian Crossfield (UCLA) on parallel computing with python. When analyzing astronomical data, one often finds oneself repeating the same tasks over and over again (e.g. fitting a model to a PSF, measuring the width of a spectral feature, etc.). Sometimes the results of one computation influence the next, [...]
