Dear Bradley, I'm no IT expert but if a virtual machine exists composed of 4 CPU's, there should be 4 physical computers involved, or am I wrong and are you working with one of these QUAD-core cpu's? First thing I would check is the athena process in the task manager. right-click on the process line and increase the priority of the process (watch out since this might lead to system instabilities). If this does not help, maybe it is possible to run 4 instances of Athena and assign a separate cpu for every instance. Or maybe run Athena on the 4 separate computers making the VM (if they are available to you anyway...). This would cut your time in 4. Just a few suggestions, I hope they help, Alexander -- Alexander Riskin Universiteit Hasselt IMO - Inorganic and Physical Chemistry Agoralaan – Building D BE-3590 Diepenbeek / Belgium tel. +32.(0)11.26.83.94 fax. +32.(0)11.26.83.23 email:alexander.riskin@uhasselt.be On 21/03/2012 14:44, ifeffit-request@millenia.cars.aps.anl.gov wrote:
