Actually, there's both: ARM scales to multiple cores per CPU (dual-core and quad-core are common, and very high core counts are on the horizon), and vendors are preparing many-CPU boxes (e.g., HP Redstone, with 288 quad core (+1 management core) systems in 4U). -Chris -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
