MarkTechPost inoshuma kuti Meta yakaunza MetaRoCE, itsva RDMA yekufambisa protocol yakagadzirirwa AI mitoro yebasa inomhanya pamaseti makuru eEthernet. Chirevo chinoti MetaRoCE inobata network sekurasikirwa kwete kuda kuburitsa pasina kurasikirwa kuburikidza nekutanga kuyerera kwekutonga, nepo programmable network interface makadhi anobata kurongeka kwepakeji, kusarudzwa kwenzira uye kudzoreredza kwakasarudzika.
MarkTechPost inoshuma kuti Meta yakaunza MetaRoCE seyakachena-sheet RDMA yekufambisa yeAI-scale Ethernet. Zvinoenderana nekubuda, iyo protocol yakagadzirirwa kutenderedza maitiro ekutaurirana emhando huru-yekudzidzira uye kushandira masumbu, uko kuungana mashandiro akadai sekuderedza zvese uye zvese-kune-zvese zvinoda akawanda accelerator kuchinjana data kakawanda. Chirevo chinoti Meta yakashanda masumbu anosvika mazana ezviuru zveGPU munzvimbo dzakawanda dzedata uye matunhu, kunyangwe zvichemo izvi zvinonzi neMarkTechPost uye hazvina kusimbiswa zvakazvimirira pano.
Iyo yakashumwa dhizaini inosiyana neyakajairwa RoCEv2 mumabatiro ainoita kusangana, kurongeka uye kurasikirwa. MarkTechPost inoti MetaRoCE inopfapfaidza mapaketi munzira dzakawanda uye inovabvumira kuti vasvike kunze kwehurongwa. Imwe neimwe pakiti inotakura ruzivo rwakakwana kuti iyo inogamuchira NIC iise data zvakananga munzvimbo yayo yekupedzisira yekurangarira, kudzivirira kurodha buffer uye kuderedza musoro-we-mutsara kuvharika. Chirevo ichi chinotiwo kubatana kwega kwega kunogona kuve neakawanda akarongedzerwa hova uye akawanda network nzira, zvichibvumira iyo yekupedzisira kudzoreredza traffic pasina kuvhura nhamba huru dzeakasiyana mitsara pairi.
Iyo yekubuda inoshuma kuti MetaRoCE inoshandisa ECN yekumaka uye ECMP nzira kubva paEthernet jira, uku ichifambisa hungwaru hwekufambisa muNIC. Zvinonzi inobvisa kudiwa kwekutanga kuyerera kwekudzora uye kumbomira mafuremu, ari pakati pekurasikirwa kweRoCE deployments. Iyo 256-bit yakasarudzika-yekubvuma chimiro inonzi inozivisa yakarasika mapaketi uye inokonzeresa kutapurirwa kwakanangwa. MarkTechPost inotsanangurawo sender-side ECN-based additive-increase, multiplicative-decrease control yakasanganiswa neanogamuchira-akapihwa fair-share rate hints.
MarkTechPost inoti Meta yakashandisa protocol pa AMD Pensando programmable NICs ndokuiedza pa64-node AMD GPU cluster inomhanya RCCL zvikwata. Chinyorwa chinoshuma yakakwira kuburitsa uye yakaderera kuyerera-kupedzisa nguva kupfuura RoCEv2 mune zvese-kuderedza uye zvese-kune-zvese kuenzanisa. Inoenderera mberi ichiti MetaRoCE yakachengeta inenge 86% kuburikidza ne1% packet kurasikirwa uye yakaramba ichipa inobatsira bandwidth pa10% kurasikirwa. Chinyorwa hachipi zvakaringana zvakazvimiririra zvinotariswa nzira, zviyero zvisina kujeka kana gadziriro yekutanga kusimbisa izvo zvawanikwa.
Hurongwa hwekuburitswa hwakataurwa hahuna kukwana. MarkTechPost inoti Meta inotarisira kuburitsa zvakatemwa kuburikidza neOpen Project, DPDK-yakagadziridzwa software referensi rekushandisa, yekuteerera suite uye libsoftmetaroce maitiro ehunhu. Iyo yekuburitsa inoisa izvo zvigadzirwa pa2026 OCP Global Summit muna Gumiguru, asi inoshandisa mutauro unokwanisa nezve nguva. Sosi yacho inotiwo mamwe mashandisirwo ehardware ari kuenderera mberi, pasina kudoma vatengesi kana kuzvipira kuwanikwa.

Nei zvichikosha
Yakakura AI kudzidziswa uye yekushandira mabasa zvinoenderana neakaungana mashandiro anofambisa data pakati peakawanda accelerator. Chifambiso chinoramba chichishanda panguva yekurasikirwa kwepaketi chinogona kuderedza zviteshi uye kuita kuti masumbu eEthernet-based AI awedzere kusimba, asi mhedzisiro yakataurwa haina kusimbiswa yakazvimiririra uye haigadziri kugadzirira kugadzira.
Chinhu chinoshanda ndechekushandisa. MuAI yakagoverwa, nhanho yekudzidzisa inogona kunonoka neinononoka nzira yekutaurirana, ichisiya anodhura accelerator akamirira. MarkTechPost's account inoratidza kuti MetaRoCE inotarisirwa kuchengetedza kutamiswa kana mamwe mapaketi kana ndege dzenetiweki dzatadza, pane kubvumidza chikanganiso chidiki kumisa boka rakakura. Kana ikagadzirwazve yakazvimirira, izvo zvinogona kuita kuti Ethernet ive nheyo inoshanduka-shanduka yemasumbu eAI uye kuderedza kutsamira pane yakanyatso kudzora kurasikirwa-mucheka masisitimu.
Iyo dhizaini inogona zvakare kukanganisa maitiro emasangano kuvaka nekushandisa network. Chirevo chinoti MetaRoCE inoda ECN uye ECMP, hunyanzvi hwakabatana zvakanyanya neEthernet switching, asi haidi kuchekesa packet, switch-side spraying, in-network telemetry kana credit-based flow control. Izvo zvinogona kuve nebasa kune vashandisi vanoshandisa yakasanganiswa-mutengesi michina kana makore nharaunda uko switch yekumisikidza inomanikidzwa. Nekudaro, kuenderana neyakajairwa Ethernet midziyo yaizoenderana neNIC, vatyairi, software stack uye masisitimu ekushanda, kwete pakuvapo kweECN neECMP.
Iyo yakashumwa nzira inoisa mutoro wakawanda pamagumo. Izvo zvinogona kurerutsa jira, asi rinogona kuwedzera kukosha kweNIC firmware, host software, yekurangarira kuisa uye kucherechedzwa. Kutadza kwaimboonekwa mukuchinja kunogona kuve maitiro ekufambisa anoda kuongororwa kutsva uye kuyedzwa kwekuteerera. Izvo zvakatsanangurwa zveOCP zvigadzirwa zvinogona kubatsira kumisikidza kudyidzana, asi kubatsira kwavo kuchaenderana nekuzara kwacho uye kuti vatengesi vanoyedza sei kuita.
Kuenzanisa neRoCEv2 kungangove kwakakosha nekuti inogadzirisa chaiyo yekuvakisa tradeoff: isingarasikike networking inogona kudzivirira kudzoreredza asi inogona kushandisa nzira dzekumbomira dzinoparadzira kusangana, nepo kurasikirwa-kushivirira dhizaini kunogona kuchengetedza nzira dzakasiyana pamutengo wekudzoreredza traffic uye endpoint kuoma. Iyo sosi inopa MetaRoCE's packet-kurasikirwa mhedzisiro sehumbowo hwekufarira nzira yekupedzisira. Mhedzisiro iyoyo inofanirwa kubatwa sekambani-yakabatana tekinoroji yakataurwa naMarkTechPost, kwete sehumbowo humbowo hwekuti kutakura-kushivirira kutakurwa kwakakwirira mune yese topology kana mutoro webasa.
Kukanganisa kweruzhinji hakuna kunanga asi kwakakura kana tekinoroji ichikura. Kuwedzera kusimba kwekubatanidza kunogona kukanganisa mutengo, kugoverwa kwenzvimbo uye musanganiswa wevatengesi weAI zvivakwa. Ivo vanogona zvakare kukanganisa mashandiro emasevhisi ekudzidzisa, kufambisa mafambiro uye sainzi mabasa anoshandisa akagoverwa accelerator. Parizvino, hapana humbowo mune kwakawanda kutumirwa, kutorwa kwevatengi, kuburitswa kwakazvimirira ongororo kana shanduko mukuwanikwa kweAI yakatarisana nevatengi.

Zvekutarisa zvinotevera
Matanho akakosha anotevera ndeekuti Meta inoburitsa zvakavimbiswa, kuita referensi uye kuteedzera suite kuburikidza neOpen Project, vangave vamwe vatengesi vachitsigira protocol, uye kana bvunzo dzakazvimirira dzichiburitsa zvakashumwa. Vatengi vanofanirwawo kutarisa humbowo kubva mukugadzirwa kwekugadzirwa kwete kuvimba chete nekutadza kufananidzwa kana chikuva chimwe chehardware.
Yekutanga verification point ndeyekuburitswa. Vaverengi vanofanirwa kutsvaga Meta's chaiyo MetaRoCE yakatarwa, referensi software uye zvekuteerera zvinhu kuburikidza neOpen Project. Iwo magwaro aizojekesa mafomu emapaketi, kudyidzana zvinodiwa, marezinesi, mamiriro ekuita, kufunga nezvekuchengetedza uye kuti nguva yaGumiguru yakasimba here kana kuti ingori chirevo chakataurwa naMarkTechPost.
Kuzvimiririra bhenji ndiyo bvunzo huru inotevera. Humbowo hunoshanda hungasanganisira mhedzisiro kubva kune anopfuura mumwechete NIC mutengesi, akasiyana switch mapuratifomu, akasiyana siyana masaizi uye mabasa anorema kupfuura maRCCL akaunganidzwa. Miedzo inofanirwa kuzivisa kubuda, muswe latency, kuyerera-kupedzisa nguva, retransmission pamusoro, CPU uye NIC mashandisirwo, maitiro ari pasi pekutadza kwakabatana uye kupora mushure mekunge ndege kana nzira isingawanikwe.
Hardware uye kuwanikwa kwesoftware kucharatidza kuti chirevo chinotsanangura tekinoroji inogona kuendesa kana purojekiti yekutanga yekuvaka. MarkTechPost inoti Meta yakaratidza MetaRoCE pa AMD Pensando programmable NICs uye kuti kumwe kuita kuri kuenderera mberi, asi hazviratidze chigadzirwa chekutengesa, chinotsigirwa mutyairi matrix kana kugadzirwa kwekugadzira. Vashandi vanofanirwa kumirira kushandiswa kwakanyorwa, zvinyorwa uye zvitsigiro zvekutsigira vasati vabata protocol sesarudzo yekutenga.
Nhamba dzakashumwa dzekurasikirwa dzinodawo kududzirwa kwakangwarira. Kuchengeta angangoita 86% kubuda pa1% kurasikirwa kwepaketi uye kuchengetedza inobatsira bandwidth pa10% kurasikirwa kunogona kuve nekureva, asi kwacho haaratidze kana kurasikirwa kwakangoitika kana kuputika, ingave yakakanganisa nzira imwe chete kana yakawanda, mafambisirwo akaitwa, kana kuti mari yekudzosera ichienzaniswa neRoCEv2 pasi pemamiriro akafanana. Kudzokorora kwakazvimiririra kunofanirwa kuyedza kusangana kwechokwadi uye maitiro ekutadza pane kungovimba chete nekudzora kuenzanisa.
Chekupedzisira, iyo indasitiri inofanirwa kuona kuti MetaRoCE inoenderana sei nemamwe maAI-networking zvirongwa, kusanganisira iyo Open Project's yakakura Ethernet basa uye inokwikwidza yekufambisa yekufambisa. Mubvunzo wakakosha hausi wekuti dhizaini yeMeta inoita zvakanaka musumbu rimwe chete, asi kana vatengesi vachigona kuishandisa nguva dzose, vashandisi vanogona kuigadzirisa, uye maapplication anogona kuishandisa pasina shanduko inodhura. Kusvika iyo mibvunzo yapindurwa, budiriro inonzwisiswa zvakanyanya sechikumbiro chezvivakwa nekuratidzira kwehardware, kwete kutsiva kunowanikwa kweRoCEv2.
