hi Patricia - links to a couple of articles that might spur your thinking.

As George mentioned, Qgis is brilliant for multithreaded rendering - particularly when installed on your multi core processing servers and accessed by Remote Desktop (RDP) which minimizes the amount of data that has to traverse your broadband link in order to visualize it.

But when it comes to the multi core geoprocessing itself, there's a wide range of tools equipped for the job. The code patterns I've shared above are on github and are PostGIS focussed - but they can be easily adapted to incorporate R, GRASS, GDAL commands and more into a single parallel pipeline job. Scripting skills are a must.

HTH
