Ngonyaka odlule eSt. Petersburg kwakukhona , enikezelwe kumasistimu ahambisanayo nasatshalaliswayo. Abaphumelele izindondo benze izethulo и (, и ), abadali babadidiyeli nezilimi zokuhlela (C++, Go, Java, Kotlin), abathuthukisi bemininingwane esabalalisiwe (i-Cassandra, i-CosmosDB, i-Yandex Database), kanye nabadali nabacwaningi bama-algorithms nezakhiwo zedatha (CRDT, Paxos, linda -izakhiwo zedatha zamahhala) . Ngokuvamile, kuleli qophelo usungakwazi kakade ukuthatha iholidi, unciphise iwindi le-IDE, uvule uhlu lwadlalwayo ku-YouTube nge I-Hydra 2019 - futhi uvumele umhleli womsebenzi alinde kancane.
Ngokuvamile, ingqungquthela enjalo ayikaze yenzeke, futhi manje izophinde yenzeke. Futhi ngemibiko ngesiNgisi, ngoba alukho ulimi olungcono lokukhuluma nge- parallel and distributed computing. Futhi ehlobo, ngoJulayi 10 no-11, ngoba izikhulumi zinesikhathi sokucwaninga nokufundisa, isibonelo, emanyuvesi aseCambridge, eRochester naseSt.
Nokho, kulokhu Hydra izobanjelwa eMoscow, lapho iningi labahlanganyeli bengqungquthela lafika ngonyaka odlule ukuzolalela imibiko mayelana nokuvumelana esabalalisiwe kanye nenkumbulo yokuthengiselana. I-Hydra entsha inohlelo oluyinkimbinkimbi, izikhulumi ezintsha kanye namaqhawe angonyaka odlule, kanye nomuzwa osuvele ujwayelekile wesasasa lama-parallel hardcore asatshalaliswe kubahlanganyeli emahholo amathathu.
Masibeke ngokushesha idekhi yamakhadi etafuleni ojenene baseByzantine bebheke phezulu - sifuna uhlelo olusha lweHydra lunemininingwane eminingi futhi luhluke. Ngesikhathi sokugcina siklwebha ngozipho, manje ake simbe sijule futhi sijule. Nazi izindikimba ze-Hydra 2020 ezinezihlobo ezihlukile zonyaka odlule:
Parallel systems:
* Algorithms & data structures
* Memory models
* Compilers, runtime
* Memory reclamation
* Testing & verification
* Hardware issues
* Non-volatile memory
* Transactional memory
* Scheduling algorithms & implementations
* Heterogeneous computing: CPU, GPU, FPGA, etc.
* Performance analysis, debugging, & optimization
Distributed systems:
* Distributed computing
* Distributed machine learning/deep learning
* State machine replication & consensus
* Fault tolerance & resilience
* Testing & verification
* Hardware issues
* Blockchain & Byzantine fault tolerance
* Distributed databases, NewSQL
* Distributed stream processing
* Scheduling algorithms & implementations
* Cluster management systems
* Security
* Performance analysis, debugging, & optimization
* Peer-to-peer, gossip protocols
* Internet of things
Ungakhuluma kanjani ngakho konke lokhu ohlelweni lwenkomfa eyodwa? Impela akulula njengokuhlola umugqa wokusebenza esitolo esisha esisabalalisiwe esicwebezelayo sisebenzisa , kodwa sizozama.
Nangu osevele esohlelweni:
(Cindy Sridharan) - umthuthukisi wezinhlelo osabalalisiwe ovela eSan Francisco, umbhali wencwadi emfushane (thatha ) futhi idumile , lapho kunesihloko esisodwa kuphela “"ingakusindisa ezinsukwini ezimbalwa zokuphumula, kodwa ikushiye ujabule. KwaHydra 2020, uCindy uzokutshela ukuthi kanjani , noma begcina isimo.
UMichael Scott (UMichael Scott) - umcwaningi ovela , eyaziwa yibo bonke abathuthukisi be-Java njengomdali we kusuka ku-Java Standard Library. Yebo, ngomklomelo we-Dijkstra we-“"futhi umnikazi . Ngonyaka odlule, uMichael unikeze okuhle kakhulu (ngokusho kwakho) umbiko ngeHydra on , futhi manje uzokhuluma ngakho и , etholakala ezinqubweni ezifanayo.
(UHeidi Howard) - kusuka ku , eyaziwa ngokudala i-algorithm yokuvumelana esabalalisiwe , kanye nokusebenza ekwenzeni i-Flexible Paxos kanye . Ngonyaka odlule, uHeidi utshele ukuthi kusebenza kanjani futhi kusebenza kanjani (omunye wemibiko engcono kakhulu), futhi manje ngizozama ukuhamba eqhweni elincanyana phakathi - futhi wabelane ngombono wakhe ngokuthi iyiphi i-algorithm engcono.
(UMartin Kleppmann) mhlawumbe ungumcwaningi odume nakakhulu ovela eNyuvesi yaseCambridge, kanye nomthuthukisi wangaphambili wezinhlelo ezinkulu zedatha, owabhala incwadi ecacile ngokumangalisayo futhi eyingqayizivele yezinhlelo ezisabalalisiwe "" Ngonyaka odlule uMartin ocwaningweni lwabo lwe-CRDT, kanye nalokho esizokutshela khona manje .
(U-Nikita Koval) ungumthuthukisi we-coroutine eqenjini le-Kotlin, uthisha wesifundo sezinhlelo ezinezintambo eziningi e-ITMO, futhi uyilungu lekomidi lezinhlelo zenkomfa ye-Hydra (yebo, yona kanye le ndatshana ekhuluma ngayo). Ngonyaka odlule u-Nikita wakhuluma ngokuhlola izakhiwo zedatha ezinemicu eminingi endaweni ye-JVM esebenzisa , futhi eHydra 2020 yena mayelana ne-SegmentQueueSynchronizer - iqinisekiswe kusetshenziswa ngoba ukukhishwa kwezinto zokuqala zokuvumelanisa izinhlelo.
Landela izimemezelo zethu ezivumelanayo: isiyonke kuzoba nemibiko ecishe ibe ngamashumi amathathu engqungqutheleni, sizokutshela ngokunye maduzane. Futhi-ke, engqungqutheleni kuzoba nezindawo zezingxoxo lapho kudingekile ukuhlola izikhulumi ngemibuzo emculweni owodwa noma eminingana kuze kube yilapho kufinyelelwa ukuvumelana okujwayelekile.
Futhi uma unenhlanhla, uMartin Kleppmann uzosayina incwadi yakho.
Yebo, ngaphambi kwengqungquthela ye-Hydra 2020, okungukuthi ngoJulayi 6-9, izoba khona - Isikole sesithathu sasehlobo ngethiyori kanye nokusebenza kwekhompyutha esabalalisiwe. Izokunikeza imizwa okunzima ukuyithola engqungqutheleni, ngakho-ke sizokhuluma ngeSikole kokuthunyelwe okuhlukile.
Yini manje? Okokuqala, landela izindaba ku-Habré nasezinkundleni zokuxhumana (, , ).
Okwesibili, uma usuvele uzwa isifiso esingenakuvinjelwa sokuhambela ingqungquthela, hlola iwebhusayithi, usungakwazi kakade .
Okwesithathu, ungaphuthelwa yithuba lokuxoxa nekomidi lohlelo lwengqungquthela ye-Hydra 2020 kumazwana. Amalungu e-PC azokujabulela ukukhuluma nawe ngezihloko zengqungquthela zesikhathi esizayo.
Sanibona eHydra!
