multiple processors
Reading this article carefully, which I quote below http://msdn.microsoft.com/en-us/libr... Improvements "Most workbooks show a significant improvement in calculation speed on a system with multiple cores. The degree of improvement depends on how many independent calculation trees the workbook contains. If you make a workbook that contains one continuous chain of formulas, it will not show any multithreaded calculation (MTC) performance gain, whereas a workbook that contains several independent chains of formulas will show gains close to the number of processors available." I get the impression that a spreadsheet which looked like this Cell_1 = 2 + 3 Cell_2 = 4 + 5 Cell_3 = Cell_1 + Cell_2 would all be done in one thread whilst most of it could be spread over two. Anyone know if this is the case? many thanks Rod |

multiple processors
Cell_1 = 2 + 3 Cell_2 = 4 + 5 Cell_3 = Cell_1 + Cell_2 I would think that Cell_1 and Cell_2 are two independant threads and can be performed in parallel. Cell_3 isn't independant since it relies on two seperate calcualtion threads and has to wait for both threads to finish before it can be calculated. -- joel ------------------------------------------------------------------------ joel's Profile: 229 View this thread: http://www.thecodecage.com/forumz/sh...d.php?t=193401 http://www.thecodecage.com/forumz |
