Thanks for the VIA warning.
Just to clarify the multicore issue, for parallelized codes, both for ab initio and molecular dynamics procedures, I have multisocket, multicore machines driven by OpenMPI. Certain procedures are not amenable to parallelization, or have not been parallelized yet, so that running multicore would expensive for nothing. As for googleearth I can't find time and interest.
