Hi Sage people, I installed Ubuntu 10.04 LTS desktop as a guest virtual machine under WIndows 7 as host on a 64-bit quad core with a Sandy Bridge i7 CPU. Like VMWare suggests I choose the number of processors as 4 when I set up the virtual machine ( it actually has 4 physical processors but they use hyper threading so it has 8 logical processors ) Everything has run fine so far but when I set up Sage 4.8 from a binary installation, I get errors like this: Error: object 'sage2' not found except the number after sage varies ( I believe it goes from 0 to 3 ) These errors seem to happen when I try to access R through Sage notebooks, I'm not positive they are limited to this context. I am new to Sage but as far as I can tell this means it is having trouble supporting the multiple cores. There should be objects sage0,sage1,sage2,sage3 that run on different cores? Am I right so far? If so, does anybody know why I am having issues like this? Is it possible I installed it wrong? Or is it more of an issue of Sage running under a VMWare Workstation VM? Any thoughts would help. Doug
