Benchmarking SAC on Intel and AMD Processors

This blog entry presents tables of timings for running the SAC code on systems with different intel and AMD cpu's. Test code was provided by Viktor Fedun and is a SAC model of a flux tube. The work was undertaken in January 2011. The test problem was allowed to run  for the first 20 iterations and the totsl time recorded. Theproblem was also run on a diffrent number of processing cores.
