CXL™ Consortium & Gen‑Z Consortium Sign Letter of Intent to Advance Interconnect Technology

Novem­ber 10, 2021 — High per­for­mance com­pu­ting con­ti­nues to evolve—meeting the ever-incre­a­sing demand for high effi­ci­en­cy, low-laten­cy, rapid and seam­less pro­ces­sing. The Gen‑Z Con­sor­ti­um was foun­ded in 2016 to crea­te a next-genera­ti­on fab­ric capa­ble of brid­ging exis­ting solu­ti­ons while enab­ling new, unboun­ded inno­va­ti­on in an open, non-pro­prie­ta­ry stan­dards body.

In 2019, the CXL™ Con­sor­ti­um laun­ched to deli­ver Com­pu­te Express Link™ (CXL™), an indus­try-sup­por­ted cache-cohe­rent inter­con­nect desi­gned for pro­ces­sors, memo­ry expan­si­on, and acce­le­ra­tors. The CXL Con­sor­ti­um and the Gen‑Z Con­sor­ti­um estab­lis­hed a joint memo­ran­dum of under­stan­ding (MOU) pro­vi­ding an oppor­tu­ni­ty for col­la­bo­ra­ti­on to defi­ne brid­ging bet­ween the pro­to­cols. This took the form of a joint working group that encou­ra­ged crea­ti­vi­ty and inno­va­ti­on bet­ween the two orga­niz­a­ti­ons toward the bet­ter­ment of the indus­try as a whole. 

Loo­king to the future, the CXL Con­sor­ti­um and Gen‑Z Con­sor­ti­um have iden­ti­fied syn­er­gies bet­ween the two con­sor­tia that resul­ted in the signing of a Let­ter of Intent which, if pas­sed and agreed upon by all par­ties, would trans­fer the Gen‑Z Spe­ci­fi­ca­ti­ons and all Gen‑Z assets to the CXL Consortium.

The intent of both orga­niz­a­ti­ons is to focus indus­try efforts rela­ted to the deve­lo­p­ment of a memo­ry cohe­rent inter­face under the CXL Con­sor­ti­um with CXL as the sole indus­try stan­dard moving for­ward. This shift will help stream­li­ne the tech­no­lo­gy deve­lo­p­ment under a sin­gle, laser-focu­sed orga­niz­a­ti­on. Mem­ber com­pa­nies will be able to dedi­ca­te resour­ces to one indus­try orga­niz­a­ti­on and eli­mi­na­te the risk of dupli­ca­ted efforts. 

We’re exci­ted about the oppor­tu­ni­ty to focus the com­pu­ting indus­try on a sin­gle spe­ci­fi­ca­ti­on moving for­ward. We’ve been working tog­e­ther sin­ce the incep­ti­on of the CXL Con­sor­ti­um, and we belie­ve that this is the right step for­ward for our mem­bers and the indus­try ecosystem.
