CCL: Linux performance using a VM appliance



 Sent to CCL by: "TJ O'Donnell" [tjo ~ acm.org]
 Although I have not run QM codes in a VM,  I've been using VMs
 for about 5 years now.  For computationally intense jobs (docking,
 clustering large databases, etc.) I get about 85-90% of the speed
 compared to the native machine.  VMs suffer when used for graphical
 tasks, although they are respectable.  Be sure to give the VM as much
 memory as you can and allow it to use all the processors.  I only
 have experience with VMWare on this front.
