Editing HyperTransport (section)

=== Multiprocessor interconnect ===
Another use for HyperTransport is as an interconnect for [[Non-Uniform Memory Access|NUMA]] [[multiprocessor]] computers. AMD used HyperTransport with a proprietary [[cache coherency]] extension as part of their Direct Connect Architecture in their [[Opteron]] and [[Athlon 64 FX]] ([[AMD Quad FX platform|Dual Socket Direct Connect (DSDC) Architecture]]) line of processors. [[#Infinity Fabric|Infinity Fabric]] used with the [[EPYC]] server CPUs is a superset of HyperTransport. The [[HORUS interconnect]] from [[Newisys]] extends this concept to larger clusters. The Aqua device from 3Leaf Systems virtualizes and interconnects CPUs, memory, and I/O.
