NUMAlink желілік технологиясының даму тарихы

Computer network technology
NUMAlink is a system interconnect developed by Silicon Graphics (SGI) for use in its distributed shared memory ccNUMA computer systems. NUMAlink was originally developed by SGI for their Origin 2000 and Onyx2 systems. At the time of these systems' introduction, it was branded as "CrayLink" during SGI's brief ownership of Cray Research. Hewlett Packard Enterprise entered an original equipment manufacturer (OEM) arrangement with Silicon Graphics International (SGI) to use Numalink as the foundation in some mission critical servers. +GenerationIntroductionBandwidthname="both directions"SystemsStanford DASH~19900.12 GB/sDASH used separate request and reply mesh networks, so this bandwidth number is not directly comparable to NUMAlink.

Notes

There was no NUMAlink 1, as SGI's engineers deemed the system interconnect used in the Stanford DASH to be the first generation NUMAlink interconnect. NUMAlink 2 (branded as CrayLink) was announced in October 1996 for the Onyx2 visualization systems, the Origin 200 and the Origin 2000 servers and supercomputers.

NUMAlink 3 is the third generation of the interconnect, introduced in 2000 and used in the Origin 3000 and Altix 3000. NUMAlink 3 is capable of 3.2 GB/s of peak bandwidth through two 1.6 GB/s unidirectional links.

NUMAlink 4 is the fourth generation of the interconnect, introduced in 2004 and used in the Altix 4000. NUMAlink 4 is capable of 6.4 GB/s of peak bandwidth through two 3.2 GB/s unidirectional links.

NUMAlink 6 is the sixth generation of the interconnect, introduced in 2012 and used in the SGI UV 2000, SGI UV 3000, SGI UV 30. NUMAlink 6 is capable of 6.7 GB/s of bidirectional peak bandwidth for up to 256 socket system and 64TB of coherent shared memory.

NUMAlink 7 is the seventh generation of the interconnect, introduced in 2014 and used in the HPE Integrity MC990 X/SGI UV 300, SGI UV 30EX, SGI UV 300H, SGI UV 300RL. NUMAlink 7 is capable of 14.94 GB/s of bidirectional peak bandwidth for up to 64 socket system and 64TB of coherent shared memory.

NUMAlink 8 is the eighth generation of the interconnect, introduced in 2017 and used in the HPE Superdome Flex. NUMAlink 8 provides 13.3 GB/s of bandwidth per port and systems using it are capable of 853.33 GB/s of bisection peak bandwidth (64 links are cut) across a 32 socket system with up to 48 TB of coherent shared memory.
