* [9fans] Plan 9 demos for 4+ CPUs? @ 2006-07-27 22:32 Andrew Hudson 2006-07-27 22:34 ` geoff 0 siblings, 1 reply; 13+ messages in thread From: Andrew Hudson @ 2006-07-27 22:32 UTC (permalink / raw) To: 9fans Has anyone given any thought to using Plan 9 as an OS vehicle for a 4-CPU or 8-CPU dog and pony show? I ask because AMD and Intel are in a big race to show that multi-core CPU's are cool and that people should buy them. AMD and Intel need SMP-capable software to show that their new CPU's and server architectures are relevant. This in turn helps make Plan 9 more relevant. First of all has anyone done 2X, 4X, or 8X benchmarks against Linux, Windows, or any other OS's? Second of all, does anyone have any demos to show off Plan 9's SMP capabilities? Something with suitable flashing lights? 8-) Thanks, Andrew ^ permalink raw reply [flat|nested] 13+ messages in thread
