Tutorial: VISION/HPC for Python-based Visual Parallel Computing
Category: Languages > Python      Posted: 22 Jun 09

The chief impediment to widespread usage of parallel computing is the difficulty in programming HPCs. Furthermore, most users work from a Windows PC so that learning UNIX as a prerequisite to parallel programming is a further obstruction. What is needed is a smooth workflow that simplifies both the p...
