And what about all those machines without support for SSE and SSE2? There is more to SixTrack than simple processor architecture. The application is sensitive to small differences in arithmetic results - the sort of differences that can emerge between Intel and AMD processors, and between Windows and Linux, for example. CERN have spent a great deal of time resolving these issues - a substantial chunk of the Beta test phase was devoted to exactly this problem. As a result the compiler in use provides good cross-platform results. If it doesn't support SSE (or SSE is not used) then it's a worthwile price to pay for good engineering results. Changing compiler is not an option - the cross-platform compatibility has already proved this doesn't deliver. Gaspode the UnDressed http://www.littlevale.co.uk |

And what about all those machines without support for SSE and SSE2? Yeah, yeah. All apps. with SSE and other advanced instructions use them depending on the CPU, they are being run on. So they will run on all CPUs and use advanced functions only on ones, that support 'em. It's been a long time since sixtrack was developed and i hope CERN can put some more effort in developing SSE enabled builds. I read about all development problems, too. Anyway, i would like to see an official reply here, and discussion in other thread in another forum. Thanks. this game has no name |
