To 64 or not to 64?

From: Hendrik van Hees on 15 Jul 2010 16:42 I'm running the 64 bit version on my Lenovo Laptop for over a year now, and there are no issues. The only problem, I ever had has been sun java in connection with jaxodraw (a gui for drawing Feynman diagrams in LaTeX with the axodraw style). There the 64-bit version had a bug, and the solution was to use openjdk instead. For 32-bit applications you can install 32-bit versions of the needed libraries. In my case, e.g., Mathematica 7.0 (home edition) needs some 32- bit libraries. Everything works smooth. I don't see much difference to the 32-bit version on my ASUS Eee-PC netbook (of course the Lenovo is pretty much faster than the Eee ;-)).

Seeing how I'm running 4 gigs of mem, I'll give it a shot and see how smoother things are at 64 bit.

An alternate view: 64 bit SMP on properly threaded applications - such as database servers - is noticeably faster even with <= 4GB. I run DB2 servers with both 32 and 64 bit dual or quad processors. Insert/delete and update operation metrics are substantially higher for 64-bit. I agree that the speed is not notably faster for desktop operations but there are a number of CPU-bound classes besides memory hogs that show noticeable speed advantages. -- Will Honea

Pete, If I want to run a 32-bits version of an application that is available both in 32-, and 64-bits, I put /usr/bin/linux32 before the command. Also /usr/bin/linux64 if I want to use the 64-bits version. So you have some control over what to run on a x86_64 installation. Kind regards, Jan Gerrit Kootstra |
